  array coil
Although none of the results differed significantly, phased-array coil MRI seems to be the best single method for the preoperative staging of rectal cancer.
      
No method provided satisfactory assessments of local N stage, although phased-array coil MRI was marginally better in assessing this important parameter.
      
EUS and phased-array coil MRI provided similar results for assessing T stage.
      
For N stage, phased-array coil MRI had the best sensitivity (63%) and the same specificity (80%) as the other methods.
      
For T stage, EUS had the best sensitivity (80%) and the same specificity (67%) as phased-array coil MRI.

Objective: To evaluate contrastenhanced MR portography (CEMRP) in diagnosing of portal hypertension. Materials and Methods: With 1.5T Siemens scanner and using of body array coil and 3D breathhold FISP sequence, contrastenhanced MR portography was performed in 30 patients with portal hypertension and 10 normal individuals. Results: The anatomic relationship of portal vein, hepatic vein and IVC was well demonstrated on MR imaging in all cases. MRI findings in patients with portal hypertension were as follows:...

Results: The anatomic relationship of portal vein, hepatic vein and IVC was well demonstrated on MR imaging in all cases. MRI findings in patients with portal hypertension were as follows: tortuous and dilated splenic vein ( n= 30), enlarged portal vein ( n= 26), varicosis in esophagus ( n= 15), stomach ( n= 22), inframesentery ( n= 11) or around portal vein ( n= 5), decreased subbranching of portal vein (BXn= 23) and delayed opacification of hepatic vein ( n= 2). Conclusion: CEMRP is a very useful technique in visualizing portal veins. It can be considered as first choice of study in diagnosing of portal hypertension.

目的:评价增强磁共振门脉造影对门脉高压症的诊断价值及探讨其在术前选择手术方式和术后评价疗效的可行性。材料与方法:对30例门脉高压症患者和10例正常人进行增强磁共振门脉造影。使用西门子1.5T超导型磁共振仪,体部序列线圈,采用三维屏气FISP、短TR/TE序列。结果:所有40例均清楚显示门静脉与肝静脉、下腔静脉的空间关系。30例门脉高压症表现为门静脉增粗(26例)、门静脉栓塞(7例)、伴有脾静脉迂曲扩张(30例);门静脉分支级数减少(23例);肝静脉延迟显影(2例);多部位出现曲张静脉(食管15例,胃底22例,肠系膜下11例,门脉附近5例)。结论:增强磁共振门脉造影的成像价值极大,可作为门脉高压症诊断及选择进一步治疗方式的最优影像学方法
