| 1 | Post-operative imaging in liver transplantation: State-of-the-art and future perspectives显示文摘Orthotopic liver transplantation(OLT)represents a major treatment for end-stage chronic liver disease,as well as selected cases of hepatocellular carcinoma and acute liver failure.The ever-increasing development of imaging modalities significantly contributed,over the last decades,to the management of recipients both in the pre-operative and post-operative period,thus impacting on graft and patients survival.When properly used,imaging modalities such as ultrasound,multidetector computed tomography,magnetic resonance imaging(MRI)and procedures of direct cholangiography are capable to provide rapid and reliable recognition and treatment of vascular and biliary complications occurring after OLT.Less defined is the role for imaging in assessing primary graft dysfunction(including rejection)or chronic allograft disease after OLT,e.g.,hepatitis C virus(HCV)recurrence.This paper:(1)describes specific characteristic of the above imaging modalities and the rationale for their use in clinical practice;(2)illustrates main imaging findings related to post-OLTcomplications in adult patients;and(3)reviews future perspectives emerging in the surveillance of recipients with HCV recurrence,with special emphasis on MRI. | Rossano Girometti Giuseppe Como Massimo Bazzocchi Chiara Zuiani | 2014 | World Journal of Gastroenterology2014，20，20： | 8 |
| 2 | Role for contrast-enhanced ultrasound in assessing complications after kidney transplant显示文摘Kidney transplantation(KT)is an effective treatment for end-stage renal disease.Despite their rate has reduced over time,post-transplant complications still represent a major clinical problem because of the associated risk of graft failure and loss.Thus,post-KT complications should be diagnosed and treated promptly.Imaging plays a pivotal role in this setting.Grayscale ultrasound(US)with color Doppler analysis is the first-line imaging modality for assessing complications,although many findings lack specificity.When performed by experienced operators,contrast-enhanced US(CEUS)has been advocated as a safe and fast tool to improve the accuracy of US.Also,when performing CEUS there is potentially no need for further imaging,such as contrast-enhanced computed tomography or magnetic resonance imaging,which are often contraindicated in recipients with impaired renal function.This technique is also portable to patients’bedside,thus having the potential of maximizing the cost-effectiveness of the whole diagnostic process.Finally,the use of blood-pool contrast agents allows translating information on graft microvasculature into time-intensity curves,and in turn quantitative perfusion indexes.Quantitative analysis is under evaluation as a tool to diagnose rejection or other causes of graft dysfunction.In this paper,we review and illustrate the indications to CEUS in the post-KT setting,as well as the main CEUS findings that can help establishing the diagnosis and planning the most adequate treatment. | Giuseppe Como Jacopo Da Re Gian Luigi Adani Chiara Zuiani Rossano Girometti | 2020 | World Journal of Radiology2020，12，8： | 3 |

| 5 | 肝移植患者重建肝动脉的彩色多普勒超声检查显示文摘目的 探讨肝移植患者不同肝动脉重建术后肝动脉频谱特征 ,比较端 -端吻合术及主动脉 -肝动脉旁路术后肝动脉的峰值血流速度 (PSV) ,舒张末期血流速度 (EDV)及阻力指数 (RI)。方法 回顾性分析了 48例肝移植术患者术后肝动脉的超声表现。其中 3 0例行端 -端吻合术 ,18例行旁路术。超声检查于术后 3~ 6个月进行 ,所有患者术后肝功能正常 ,无肝功能不全临床表现。结果 行端 -端吻合术者 ,肝动脉阻力指数较低 ,而行旁路术者肝动脉阻力指数较高。前者PSV平均为 ( 5 7± 16)cm s ,EDV平均为 ( 2 5± 14 )cm s ,RI 0 .3 3~ 0 .71,平均 0 .5 8± 0 .13 ;后者PSV平均为 ( 62± 16)cm s ,EDV平均为 ( 12± 4)cm s ,RI 0 .7~ 0 .78,平均 0 .77± 0 .0 6。结论 多普勒频谱形态及RI值与重建肝动脉的长度及管径有关 ,端 -端吻合者 ,重建的肝动脉路径短 ,管径细但均匀 ,故血流阻力低 ;而旁路术者 ,重建的肝动脉路径长 ,管径变化大 ,因此 ,血流阻力大。在肝移植术后的超声检查及并发症诊断中 。 | Alessandro De Condia Giuseppe Como Luigi Tedeschi 黄晓玲 | 2003 | 临床超声医学杂志2003，5，5： | 1 |
