1New ultrasound techniques for lymph node evaluation显示文摘Conventional ultrasound(US)is the recommended imaging method for lymph node(LN)diseases with the advantages of high resolution,real time evaluation and relative low costs.Current indications of transcutaneous ultrasound and endoscopic ultrasound include the detection and characterization of lymph nodes and the guidance for LN biopsy.Recent advances in US technology,such as contrast enhanced ultrasound(CEUS),contrast enhanced endoscopic ultrasound(CE-EUS),and real time elastography show potential to improve the accuracy of US for the differential diagnosis of benign and malignant lymph nodes.In addition,CEUS and CE-EUS have been also used for the guidance of fine needle aspiration and assessment of treatment response.Complementary to size criteria,CEUS could also be used to evaluate response of tumor angiogenesis to anti-angiogenic therapies.In this paper we review current literature regarding evaluation of lymphadenopathy by new and innovative US techniques.Xin-Wu Cui Christian Jenssen Adrian Saftoiu Andre Ignee Christoph F Dietrich 2013World Journal of Gastroenterology2013,19,30:25
2Artificial intelligence in medical imaging of the liver显示文摘Artificial intelligence(AI), particularly deep learning algorithms, is gaining extensive attention for its excellent performance in image-recognition tasks. They can automatically make a quantitative assessment of complex medical image characteristics and achieve an increased accuracy for diagnosis with higher efficiency. AI is widely used and getting increasingly popular in the medical imaging of the liver, including radiology, ultrasound, and nuclear medicine. AI can assist physicians to make more accurate and reproductive imaging diagnosis and also reduce the physicians' workload. This article illustrates basic technical knowledge about AI, including traditional machine learning and deep learning algorithms, especially convolutional neural networks, and their clinical application in the medical imaging of liver diseases, such as detecting and evaluating focal liver lesions, facilitating treatment, and predicting liver treatment response. We conclude that machine-assisted medical services will be a promising solution for future liver medical care. Lastly, we discuss the challenges and future directions of clinical application of deep learning techniques.Li-Qiang Zhou Jia-Yu Wang Song-Yuan Yu Ge-Ge Wu Qi Wei You-Bin Deng Xing-Long Wu Xin-Wu Cui Christoph F Dietrich 2019World Journal of Gastroenterology2019,25,6:21
3Benign liver tumors in pediatric patients-Review with emphasis on imaging features显示文摘Benign hepatic tumors are commonly observed in adults,but rarely reported in children.The reasons for this remain speculative and the exact data concerning the incidence of these lesions are lacking.Benign hepatic tumors represent a diverse group of epithelial and mesenchymal tumors.In pediatric patients,most benign focal liver lesions are inborn and may grow like the rest of the body.Knowledge of pediatric liver diseases and their imaging appearances is essential in order to make an appropriate differential diagnosis.Selection of the appropriate imaging test is challenging,since it depends on a number of age-related factors.This paper will discuss the most frequently encountered benign liver tumors in children(infantile hepatic hemangioendothelioma,mesenchymal hamartoma,focal nodular hyperplasia,nodular regenerative hyperplasia,and hepatocellular adenoma),as well as a comparison to the current knowledge regarding such tumors in adult patients.The current emphasis is on imaging features,which are helpful not only for the initial diagnosis,but also for pre- and posttreatment evaluation and follow-up.In addition,future perspectives of contrast-enhanced ultrasound(CEUS) in pediatric patients are highlighted,with descriptions of enhancement patterns for each lesion being discussed.The role of advanced imaging tests such as CEUS and magnetic resonance imaging,which allow for non-invasive assessment of liver tumors,is of utmost importance in pediatric patients,especially when repeated imaging tests are needed and radiation exposure should be avoided.Liliana Chiorean Xin-Wu Cui Andrea Tannapfel Doris Franke Martin Stenzel Wojciech Kosiak Dagmar Schreiber-Dietrich J?rg Jüngert Jian-Min Chang Christoph F Dietrich 2015World Journal of Gastroenterology2015,21,28:16

5Artificial intelligence in breast ultrasound显示文摘Artificial intelligence(AI) is gaining extensive attention for its excellent performance in image-recognition tasks and increasingly applied in breast ultrasound. AI can conduct a quantitative assessment by recognizing imaging information automatically and make more accurate and reproductive imaging diagnosis. Breast cancer is the most commonly diagnosed cancer in women,severely threatening women's health, the early screening of which is closely related to the prognosis of patients. Therefore, utilization of AI in breast cancer screening and detection is of great significance, which can not only save time for radiologists, but also make up for experience and skill deficiency on some beginners. This article illustrates the basic technical knowledge regarding AI in breast ultrasound, including early machine learning algorithms and deep learning algorithms, and their application in the differential diagnosis of benign and malignant masses. At last, we talk about the future perspectives of AI in breast ultrasound.Ge-Ge Wu Li-Qiang Zhou Jian-Wei Xu Jia-Yu Wang Qi Wei You-Bin Deng Xin-Wu Cui Christoph F Dietrich 2019World Journal of Radiology2019,11,2:12
6Endoscopic ultrasound elastography: current status and future perspectives显示文摘Elastography is a new ultrasound modality that provides images and measurements related to tissue stiffness. Endoscopic ultrasound(EUS) has played an important role in the diagnosis and management of numerous abdominal and mediastinal diseases. Elastography by means of EUS examination can assess the elasticity of tumors in the proximity of the digestive tract that are hard to reach with conventional transcutaneous ultrasound probes, such as pancreatic masses and mediastinal or abdominal lymph nodes, thus improving the diagnostic yield of the procedure. Results from previous studies have promised benefits for EUS elastography in the differential diagnosis of lymph nodes, as well as for assessing masses with pancreatic or gastrointestinal(GI) tract locations. It is important to mention that EUS elastography is not considered a modality that can replace biopsy. However, it may be a useful adjunct, improving the accuracy of EUSfine needle aspiration biopsy(EUS-FNAB) by selecting the most suspicious area to be targeted. Even more, it may be useful for guiding further clinical management when EUS-FNAB is negative or inconclusive. In the present paper we will discuss the current knowledge of EUS elastography, including the technical aspects, along with its applications in the differential diagnosis between benign and malignant solid pancreatic masses and lymph nodes, as well as its aid in the differentiation between normal pancreatic tissues and chronic pancreatitis. Moreover, the emergent indication and future perspectives are summarized, such as the benefit of EUS elastography in EUS-guided fine needle aspiration biopsy, and its uses for characterization of lesions in liver, biliary tract, adrenal glands and GI tract.Xin-Wu Cui Jian-Min Chang Quan-Cheng Kan Liliana Chiorean Andre Ignee Christoph F Dietrich 2015World Journal of Gastroenterology2015,21,47:8
7Ultrasonographic imaging of inflammatory bowel disease in pediatric patients显示文摘Inflammatory bowel disease(IBD) is one of the most common chronic gastrointestinal diseases in pediatric patients.Choosing the optimal imaging modality for the assessment of gastrointestinal disease in pediatric patients can be challenging.The invasiveness and patient acceptance,the radiation exposure and the quality performance of the diagnostic test need to be considered.By reviewing the literature regarding imaging in inflammatory bowel disease the value of ultrasound in the clinical management of pediatric patients is highlighted.Transabdominal ultrasound is a useful,noninvasive method for the initial diagnosis of IBD in children;it also provides guidance for therapeutic decisions and helps to characterize and predict the course of the disease in individual patients.Ultrasound techniques including color Doppler imaging and contrast-enhanced ultrasound are promising imaging tools to determine disease activity and complications.Comparative studies between different imaging methods are needed.Liliana Chiorean Dagmar Schreiber-Dietrich Barbara Braden Xin-Wu Cui Reiner Buchhorn Jian-Min Chang Christoph F Dietrich 2015World Journal of Gastroenterology2015,21,17:7
8Mechanical Behaviour and Microstructure Evolution of Superplastic Mg-8.4 wt pct Li Alloy and Effect of Grain Size and Phase Ratio on Its Elongation显示文摘Mechanical properties and microstructure evolution of Mg-8.4 wt pct Li alloy have been investi- gated. The superplastic elongation-to-failure 920% at 573 K and initial strain rate of 5 × 10-4 s-1 at low nominal stress 2 MPa has been demonstrated. It was shown through optical microstructure that the average grain sizes at gauge length section before and after superplastic tension and at grip section were 7.5 μm, 31.7 μm and 20 μm respectively, indicating significant deformation induced grain growth and static grain growth. Comparison of experiment data with published data for superplastic Mg-Li alloys shows that fine grain size and about 50 to 50 phase ratio contribute to achieving the largest superplasticity. Some related research works in other alloys are compiled and further evidences to such theoretic argument are provided.Cao, FR Cui, JZ Wen, JL Lei, F 2000Journal of Materials Science & Technology2000,16,1:5
9Nomogram for predicting transmural bowel infarction in patients with acute superior mesenteric venous thrombosis显示文摘BACKGROUND The prognosis of acute mesenteric ischemia(AMI)caused by superior mesenteric venous thrombosis(SMVT)remains undetermined and early detection of transmural bowel infarction(TBI)is crucial.The predisposition to develop TBI is of clinical concern,which can lead to fatal sepsis with hemodynamic instability and multi-organ failure.Early resection of necrotic bowel could improve the prognosis of AMI,however,accurate prediction of TBI remains a challenge for clinicians.When determining the eligibility for explorative laparotomy,the underlying risk factors for bowel infarction should be fully evaluated.AIM To develop and externally validate a nomogram for prediction of TBI in patients with acute SMVT.METHODS Consecutive data from 207 acute SMVT patients at the Wuhan Tongji Hospital and 89 patients at the Guangzhou Nanfang Hospital between July 2005 and December 2018 were included in this study.They were grouped as training and external validation cohort.The 207 cases(training cohort)from Tongji Hospital were divided into TBI and reversible intestinal ischemia groups based on the final therapeutic outcomes.Univariate and multivariate logistic regression analyses were conducted to identify independent risk factors for TBI using the training data,and a nomogram was subsequently developed.The performance of the nomogram was evaluated with respect to discrimination,calibration,and clinical usefulness in the training and external validation cohort.RESULTS Univariate and multivariate logistic regression analyses identified the following independent prognostic factors associated with TBI in the training cohort:The decreased bowel wall enhancement(OR=6.37,P<0.001),rebound tenderness(OR=7.14,P<0.001),serum lactate levels>2 mmol/L(OR=3.14,P=0.009)and previous history of deep venous thrombosis(OR=6.37,P<0.001).Incorporating these four factors,the nomogram achieved good calibration in the training set[area under the receiver operator characteristic curve(AUC)0.860;95%CI:0.771-0.925]and the external validation set(AUC 0.851;95%CI:0.796-0.897).The positive and negative predictive values(95%CIs)of the nomogram were calculated,resulting in positive predictive values of 54.55%(40.07%-68.29%)and 53.85%(43.66%-63.72%)and negative predictive values of 93.33%(82.14%-97.71%)and 92.24%(85.91%-95.86%)for the training and validation cohorts,respectively.Based on the nomogram,patients who had a Nomo-score of more than 90 were considered to have high risk for TBI.Decision curve analysis indicated that the nomogram was clinically useful.CONCLUSION The nomogram achieved an optimal prediction of TBI in patients with AMI.Using the model,the risk for an individual patient inclined to TBI can be assessed,thus providing a rational therapeutic choice.Meng Jiang Chang-Li Li Chun-Qiu Pan Wen-Zhi Lv Yu-Fei Ren Xin-Wu Cui Christoph F Dietrich 2020World Journal of Gastroenterology2020,26,26:4
