2Contrast-enhanced ultrasound of histologically proven hepatic epithelioid hemangioendothelioma显示文摘AIM: To analyze contrast-enhanced ultrasound(CEUS) features of histologically proven hepatic epithelioid hemangioendothelioma(HEHE) in comparison to other multilocular benign focal liver lesions(FLL).METHODS: Twenty-five patients with histologically proven HEHE and 45 patients with histologically proven multilocular benign FLL were retrospectively reviewed. Four radiologists assessed the CEUS enhancement pattern in consensus.RESULTS: HEHE manifested as a single(n = 3) or multinodular(n = 22) FLL. On CEUS, HEHE showed rim-like(18/25, 72%) or heterogeneous hyperenhancement(7/25, 28%) in the arterial phase and hypoenhancement(25/25, 100%) in the portal venous and late phases(PVLP), a sign of malignancy. Eighteen patients showed central unenhanced areas(18/25, 72%); in seven patients(7/25, 28%), more lesions were detected in the PVLP. In contrast, all patients with hemangioma and focal nodular hyperplasia showed hyperenhancement as the most distinctive feature(P < 0.01).CONCLUSION: CEUS allows for characterization of unequivocal FLL. By analyzing the hypoenhancement in the PVLP, CEUS can determine the malignant nature of HEHE.Yi Dong Wen-Ping Wang Vito Cantisani Mirko D'Onofrio Andre Ignee Lorenzo Mulazzani Adrian Saftoiu Zeno Sparchez Ioan Sporea Christoph F Dietrich 2016World Journal of Gastroenterology2016,22,19:21
3Autoimmune pancreatitis:Multimodality non-invasive imaging diagnosis显示文摘Autoimmune pancreatitis(AIP)is characterized by obstructive jaundice,a dramatic clinical response to steroids and pathologically by a lymphoplasmacytic infiltrate,with or without a pancreatic mass.Type 1AIP is the pancreatic manifestation of an Ig G4-related systemic disease and is characterized by elevated Ig G4serum levels,infiltration of Ig G4-positive plasma cells and extrapancreatic lesions.Type 2 AIP usually has none or very few Ig G4-positive plasma cells,no serum Ig G4 elevation and appears to be a pancreas-specific disorder without extrapancreatic involvement.AIP is diagnosed in approximately 2%-6%of patients that undergo pancreatic resection for suspected pancreatic cancer.There are three patterns of autoimmune pancreatitis:diffuse disease is the most common type,with a diffuse,'sausage-like'pancreatic enlargement with sharp margins and loss of the lobular contours;focal disease is less common and manifests as a focal mass,often within the pancreatic head,mimicking a pancreatic malignancy.Multifocal involvement can also occur.In this paper we describe the features of AIP at ultrasonography,computed tomography,magnetic resonanceand positron emission tomography/computed tomography imaging,focusing on diagnosis and differential diagnosis with pancreatic ductal adenocarcinoma.It is of utmost importance to make an early correct differential diagnosis between these two diseases in order to identify the optimal therapeutic strategy and to avoid unnecessary laparotomy or pancreatic resection in AIP patients.Non-invasive imaging plays also an important role in therapy monitoring,in follow-up and in early identification of disease recurrence.Stefano Crosara Mirko D'Onofrio Riccardo De Robertis Emanuele Demozzi Stefano Canestrini Giulia Zamboni Roberto Pozzi Mucelli 2014World Journal of Gastroenterology2014,20,45:16
4Pancreatic neuroendocrine neoplasms: Magnetic resonance imaging features according to grade and stage显示文摘AIM To describe magnetic resonance(MR) imaging features of pancreatic neuroendocrine neoplasms(Pan NENs) according to their grade and tumor-nodes-metastases stage by comparing them to histopathology and todetermine the accuracy of MR imaging features in predicting their biological behavior.METHODS This study was approved by our institutional review board; requirement for informed patient consent was waived due to the retrospective nature of the study. Preoperative MR examinations of 55 Pan NEN patients(29 men, 26 women; mean age of 57.6 years, range 21-83 years) performed between June 2013 and December 2015 were reviewed. Qualitative and quantitative features were compared between tumor grades and stages determined by histopathological analysis.RESULTS Ill defined margins were more common in G2-3 and stage Ⅲ-Ⅳ PanN ENs than in G1 and low-stage tumors(P < 0.001); this feature had high specificity in the identification of G2-3 and stage Ⅲ-Ⅳ tumors(90.3% and 96%, 95%CI: 73.1-97.5 and 77.7-99.8). The mean apparent diffusion coefficient value was significantly lower in G2-3 and stage Ⅲ-Ⅳ lesions compared to well differentiated and low-stage tumors(1.09 × 10-3 mm2/s vs 1.45 × 10-3 mm2/s and 1.10 × 10-3 mm2/s vs 1.53 × 10-3 mm2/s, P = 0.003 and 0.001). Receiving operator characteristic analysis determined optimal cutoffs of 1.21 and 1.28 × 10-3 mm2/s for the identification of G2-3 and stage Ⅲ-Ⅳ tumors, with sensitivity and specificity values of 70.8/80.7% and 64.5/64%(95%CI: 48.7-86.6/60-92.7 and 45.4-80.2/42.6-81.3).CONCLUSION MR features of PanN ENs vary according to their grade of differentiation and their stage at diagnosis and could predict the biological behavior of these tumors.Riccardo De Robertis Sara Cingarlini Paolo Tinazzi Martini Silvia Ortolani Giovanni Butturini Luca Landoni Paolo Regi Roberto Girelli Paola Capelli Stefano Gobbo Giampaolo Tortora Aldo Scarpa Paolo Pederzoli Mirko D'Onofrio 2017World Journal of Gastroenterology2017,23,2:16
5Diffusion-weighted imaging of pancreatic cancer显示文摘Magnetic resonance imaging(MRI) is a reliable and accurate imaging method for the evaluation of patients with pancreatic ductal adenocarcinoma(PDAC). Diffusion-weighted imaging(DWI) is a relatively recent technological improvement that expanded MRI capabilities, having brought functional aspects into conventional morphologic MRI evaluation. DWI can depict the random diffusion of water molecules within tissues(the so-called Brownian motions). Modifications of water diffusion induced by different factors acting on the extracellular and intracellular spaces, as increased cell density, edema, fibrosis, or altered functionality of cell membranes, can be detected using this MR sequence. The intravoxel incoherent motion(IVIM) model is an advanced DWI technique that consent a separate quantitative evaluation of all the microscopic random motions that contribute to DWI, which are essentially represented by molecular diffusion and blood microcirculation(perfusion). Technological improvements have made possible the routine use of DWI during abdominal MRI study. Several authors have reported that the addition of DWI sequence can be of value for the evaluation of patients with PDAC, especially improving the staging; nevertheless, it is still unclear whether and how DWI could be helpful for identification, characterization, prognostic stratification and follow-up during treatment. The aim of this paper is to review up-to-date literature data regarding the applications of DWI and IVIM to PDACs.Riccardo De Robertis Paolo Tinazzi Martini Emanuele Demozzi Flavia Dal Corso Claudio Bassi Paolo Pederzoli Mirko D'Onofrio 2015World Journal of Radiology2015,7,10:14
6Noninvasive diagnosis of cirrhosis:A review of different imaging modalities显示文摘Progressive hepatic fibrosis can lead to cirrhosis,so its early detection is fundamental.Staging fibrosis is also critical for prognosis and management.The gold standard for these aims is liver biopsy,but it has several drawbacks,as it is invasive,expensive,has poor acceptance,is prone to inter observer variability and sampling errors,has poor repeatability,and has a risk of complications and mortality.Therefore,non-invasive imaging tests have been developed.This review mainly focuses on the role of transient elastography,acoustic radiation force impulse imaging,and magnetic resonance-based methods for the noninvasive diagnosis of cirrhosis.Riccardo De Robertis Mirko D'Onofrio Emanuele Demozzi Stefano Crosara Stefano Canestrini Roberto Pozzi Mucelli 2014World Journal of Gastroenterology2014,20,23:12
7Liver volumetry:Is imaging reliable?Personal experience and review of the literature显示文摘The amount of the future liver remnant volume is fun-damental for hepato-biliary surgery, representing animportant potential risk-factor for the development ofpost-hepatectomy liver failure. Despite this, there isno uniform consensus about the amount of hepaticparenchyma that can be safely resected, nor about themodality that should be chosen for this evaluation. Thepre-operative evaluation of hepatic volume, along witha precise identification of vascular and biliar anatomyand variants, are therefore necessary to reduce surgi-cal complications, especially for extensive resections.Some studies have tried to validate imaging methods[ultrasound, computed tomography(CT), magneticresonance imaging] for the assessment of liver volume,but there is no clear evidence about the most accuratemethod for this evaluation. Furthermore, this volumet-ric evaluation seems to have a certain degree of error,tending to overestimate the actual hepatic volume,therefore some conversion factors, which should givea more reliable evaluation of liver volume, have been proposed. It is widespread among non-radiologists the use of independent software for an off-site volumetric analysis, performed on digital imaging and communica-tions in medicine images with their own personal com-puter, but very few studies have provided a validation of these methods. Moreover, while the pre-transplanta-tion volumetric assessment is fundamental, it remains unclear whether it should be routinely performed in all patients undergoing liver resection. In this editorial the role of imaging in the estimation of liver volume is dis-cussed, providing a review of the most recent literature and a brief personal series of correlations between liver volumes and resection specimens' weight, in order to assess the precision of the volumetric CT evaluation.Mirko D'Onofrio Riccardo De Robertis Emanuele Demozzi Stefano Crosara Stefano Canestrini Roberto Pozzi Mucelli 2014World Journal of Radiology2014,6,4:11
8Prognostication and response assessment in liver and pancreatic tumors:The new imaging显示文摘Diffusion-weighted imaging(DWI), dynamic contrastenhanced magnetic resonance imaging(DCE-MRI) and perfusion computed tomography(CT) are technical improvements of morphologic imaging that can evaluate functional properties of hepato-bilio-pancreatic tumors during conventional MRI or CT examinations.Nevertheless, the term 'functional imaging' is commonly used to describe molecular imaging techniques, as positron emission tomography(PET)CT/MRI, which still represent the most widely used methods for the evaluation of functional properties of solid neoplasms; unlike PET or single photon emission computed tomography, functional imaging techniques applied to conventional MRI/CT examinations do not require the administration of radiolabeled drugs or specific equipments. Moreover, DWI and DCE-MRI can be performed during the same session, thus providing a comprehensive 'one-step' morphological and functional evaluation of hepato-bilio-pancreatic tumors. Literature data reveal that functional imaging techniques could be proposed for the evaluation of these tumors before treatment, given that they may improve staging and predict prognosis or clinical outcome. Microscopic changes within neoplastic tissues induced by treatments can be detected and quantified with functional imaging,therefore these techniques could be used also for posttreatment assessment, even at an early stage. The aim of this editorial is to describe possible applications of new functional imaging techniques apart frommolecular imaging to hepatic and pancreatic tumors through a review of up-to-date literature data, with a particular emphasis on pathological correlations,prognostic stratification and post-treatment monitoring.Riccardo De Robertis Paolo Tinazzi Martini Emanuele Demozzi Gino Puntel Silvia Ortolani Sara Cingarlini Andrea Ruzzenente Alfredo Guglielmi Giampaolo Tortora Claudio Bassi Paolo Pederzoli Mirko D'Onofrio 2015World Journal of Gastroenterology2015,21,22:10
9Copper Delivery by the Copper Chaperone for Chloroplast and Cytosolic Copper/Zinc- Superoxide Dismutases: Regulation and Unexpected Phenotypes in an Arabidopsis Mutant显示文摘铜(Cu ) 是作为与 plastocyanin 和 Cu/Zn superoxide dismutase (Cu/ZnSOD ) 联系的一个余因子在叶绿体发现的重要矿物质营养素。Superoxide dismutases 是在减少氧化应力与建议角色在很氧的有机体发现的 metallo 酶。在 Arabidopsis 的几最近的研究显示出那 microRNAs 和一个 SQUAMOSA 倡导者绑定 protein-like7 (SPL7 ) 抄写因素函数到下面调整许多 Cu 蛋白质的表达式包括在质体和 cytosol 的 Cu/ZnSOD,在低 Cu 上的生长期间。植物为把 Cu 送到 Cu/ZnSODs 的草皮(CCS ) 包含 Cu 女伴,并且,在 Arabidopsis, cytosolic 和 plastidic CCS 版本被一基因编码。在这研究,我们证明 Arabidopsis CCS 抄本层次被 Cu 调整,由 microRNA 调停了 398 那以前没被预言指向 CCS。microRNA 目标地点在 Oryza sativa 的 CCS 被保存。数据建议那调整 Cu 的 microRNAs 可以有更多的 mRNA 目标比以前被预言。CCS 空异种不在叶绿体和 cytosol 举办可测量的草皮活动,显示为 CCS 的一个绝对要求。当 CCS 空异种在高 Cu 媒介上是成年的时,它缺乏两 Fe superoxide dismutase (FeSOD ) 和 Cu/ZnSOD 活动。然而,这没导致视觉显型,没有光合的缺乏被检测,甚至在高轻的应力以后。这些结果显示 Cu/ZnSOD 不在处于实验室条件的生长期间是光合的抗氧化剂系统的一个枢轴的部件。Christopher M.

10Acoustic radiation force impulse of the liver显示文摘Acoustic radiation force impulse(ARFI)imaging is a new and promising ultrasound-based diagnostic technique that,evaluating the wave propagation speed,allows the assessment of the tissue stiffness.ARFI is implemented in the ultrasound scanner.By short-duration acoustic radiation forces(less than 1 ms),localized displacements are generated in a selected region of interest not requiring any external compression so reducing the operator dependency.The generated wave scan provides qualitative or quantitative(wave velocity values)responses.Several non-invasive methods for assessing the staging of fibrosis are used,in order to avoid liver biopsy.Liver function tests and transient elastography are non-invasive,sensitive and accurate tools for the assessment of liver fibrosis and for the discrimination between cirrhotic and non-cirrhotic liver.Many published studies analyse ARFI performance and feasibility in studying diffuse liver diseases and compare them to other diagnostic imaging modalities such as conventional ultrasonography and transient elastography.Solid focal liver lesions,both benign and malignant,are common findings during abdominal examinations.The accurate characterization and differential diagnosis are important aims of all the imaging modalities available today.Only few papers describe the application of ARFI technology in the study of solid focal liver lesions,with different results.In the present study,the existing literature,to the best of our knowledge,about ARFI application on diffuse and focal liver pathology has been evaluated and results and statistical analyses have been compared,bringing to the conclusion that ARFI can be used in the study of the liver with similar accuracy as transient elastography in diagnosing significant fibrosis or cirrhosis and has got some advantages in respect to transient elastography since it does not require separate equipment,better displays anatomical structures and measurements can be successfully carried out almost in every patient.Mirko D'Onofrio Stefano Crosara Riccardo De Robertis Stefano Canestrini Emanuele Demozzi Anna Gallotti Roberto Pozzi Mucelli 2013World Journal of Gastroenterology2013,19,30:9
11Contrast-enhanced ultrasound of the pancreas显示文摘The introduction of contrast-enhanced ultrasonography(CEUS) has led to major improvements in the diagnostic capabilities of ultrasound(US).The innovative use of CEUS for study of the pancreas has created the need for a definition of the most frequent dynamic features of solid and cystic masses.CEUS is less expensive compared to computed tomography and magnetic resonance imaging and is able to significantly improve the accuracy of US,allowing better characterization and staging of pancreatic pathologies.Mirko D'Onofrio Anna Gallotti Francesco Principe Roberto Pozzi Mucelli 2010World Journal of Radiology2010,2,3:8
12Percutaneous ablation of pancreatic cancer显示文摘Pancreatic ductal adenocarcinoma is a highly aggressive tumor with an overall 5-year survival rate of less than 5%. Prognosis and treatment depend on whether the tumor is resectable or not, which mostly depends on how quickly the diagnosis is made. Chemotherapy and radiotherapy can be both used in cases of nonresectable pancreatic cancer. In cases of pancreatic neoplasm that is locally advanced, non-resectable, but non-metastatic, it is possible to apply percutaneous treatments that are able to induce tumor cytoreduction. The aim of this article will be to describe the multiple currently available treatment techniques(radiofrequency ablation, microwave ablation, cryoablation, and irreversible electroporation), their results, and their possible complications, with the aid of a literature review.Mirko D'Onofrio Valentina Ciaravino Riccardo De Robertis Emilio Barbi Roberto Salvia Roberto Girelli Salvatore Paiella Camilla Gasparini Nicolò Cardobi Claudio Bassi 2016World Journal of Gastroenterology2016,22,44:7
13Radiofrequency ablation of locally advanced pancreatic adenocarcinoma:An overview显示文摘Radiofrequency ablation(RFA)of pancreatic neoplasms is restricted to locally advanced,non-resectable but nonmetastatic tumors.RFA of pancreatic tumors is nowadays an ultrasound-guided procedure performed during laparotomy in open surgery.Intraoperative ultrasound covers the mandatory role of staging,evaluation of feasibility,guidance and monitoring of the procedure.Different types of needle can be used.The first aim in the evaluation of RFA as a treatment for locally advanced pancreatic ductal adenocarcinoma,in order of evaluation but not of importance,is to determine the feasibility of the procedure.The second aim is to establish the effect of RFA on tumoral mass in terms of necrosis andcytoreduction.The most important aim,third in order of evaluation,is the potential improvement of quality of life and survival rate.Nowadays,only a few studies assess the feasibility of the procedure.The present paper is an overview of RFA for pancreatic adenocarcinoma.Mirko D’Onofrio Emilio Barbi Roberto Girelli Enrico Martone Anna Gallotti Roberto Salvia Paolo Tinazzi Martini Claudio Bassi Paolo Pederzoli Roberto Pozzi Mucelli 2010World Journal of Gastroenterology2010,16,28:6
14Comparison of imaging-based and pathological dimensions in pancreatic neuroendocrine tumors显示文摘AIM To establish the ability of magnetic resonance(MR) and computer tomography(CT) to predict pathologic dimensions of pancreatic neuroendocrine tumors(Pan NET) in a caseload of a tertiary referral center.METHODS Patients submitted to surgery for Pan NET at the Surgical Unit of the Pancreas Institute with at least 1 preoperative imaging examination(MR or CT scan) from January 2005 to December 2015 were included and data retrospectively collected. Exclusion criteria were: multifocal lesions, genetic syndromes, microadenomas or mixed tumors, metastatic disease and neoadjuvant therapy. Bland-Altman(BA) and Mountain-Plot(MP) statistics were used to compare size measured by each modality with the pathology size. Passing-Bablok(PB) regression analysis was used to check the agreement between MR and CT.RESULTS Our study population consisted of 292 patients. Seventy-nine(27.1%) were functioning Pan NET. The mean biases were 0.17 ± 7.99 mm, 1 ± 8.51 mm and 0.23 ± 9 mm, 1.2 ± 9.8 mm for MR and CT, considering the overall population and the subgroup of non-functioning-Pan NET, respectively. Limits of agreement(LOA) included the vast majority of observations, indicating a good agreement between imaging and pathology. The MP further confirmed this finding and showed that the two methods are unbiased with respect to each other. Considering ≤ 2 cm non-functioning-Pan NET, no statistical significance was found in the size estimation rate of MR and CT(P = 0.433). PBR analysis did not reveal significant differences between MR, CT and pathology.CONCLUSION MR and CT scan are accurate and interchangeable imaging techniques in predicting pathologic dimensions of Pan NET.Salvatore Paiella Harmony Impellizzeri Elisabetta Zanolin Giovanni Marchegiani Marco Miotto Anna Malpaga Riccardo De Robertis Mirko D'Onofrio Borislav Rusev Paola Capelli Sara Cingarlini Giovanni Butturini Maria Vittoria Davì Antonio Amodio Claudio BassiAldo Scarpa Roberto Salvia Luca Landoni 2017World Journal of Gastroenterology2017,23,17:4

20Serous pancreatic neoplasia, data and review显示文摘AIM To describe the imaging features of serous neoplasms of the pancreas using ultrasound, endoscopic ultrasound, computed tomography and magnetic resonance imaging.METHODS This multicenter international collaboration enhances a literature review to date, reporting features of 287 histologically confirmed cases of serous pancreatic cystic neoplasms(SPN). RESULTS Female predominance is seen with most SPN presenting asymptomatically in the 5th through 7th decade. Mean lesion size was 38.7 mm, 98% were single, 44.2% cystic, 46% mixed cystic and solid, and 94% hypoechoic on B-mode ultrasound. Vascular patterns and contrast-enhancement profiles are described as hypervascular and hyperenhancing.CONCLUSION The described ultrasound features can aid differentiation of SPN from other neoplastic lesions under most circumstances.Christoph F Dietrich Yi Dong Christian Jenssen Valentina Ciaravino Michael Hocke Wen-Ping Wang Eike Burmester Kathleen Moeller Nathan SS Atkinson Paola Capelli Mirko D’Onofrio 2017World Journal of Gastroenterology2017,23,30:3
