3.0T磁共振成像对肝门部胆管癌的诊断价值

目的评价3.0T磁共振成像在肝门部胆管癌疾病中的诊断价值及其优势。方法收集26例经手术和病理证实的肝门部胆管癌患者的3.0T磁共振的常规MRI、MRCP图像及B超诊断,其中12例行3D-VIBE动态增强,10例同期行CT检查,并与病理结果对比,比较它们的诊断价值。结果常规MRI结合MRCP对本组病例的定位准确率为100%,定性准确率为92.3%,超声的定位准确率92.3%,定性准确率65.4%,两者对病灶定性的准确率差异有统计学意义(P0.05);12例3D-VIBE动态增强比MR平扫多发现小病灶3例,定性诊断更加可靠;10例CT扫描2例误诊,MR检查均定性正确。结论3.0TMR平扫及MRCP对肝门部胆管癌诊断及分型具有重要价值,高于同期B超、CT诊断价值;结合3D-VIBE序列动态增强扫描则能清楚显示动脉期,门静脉期及实质期等各个时相,不但有利于小病灶的发现,还能提供病灶的血供情况,为临床提供更高价值的影像信息。

Diagnostic Value of Magnetic Resonance Imaging for the Hilar Cholangiocarcinoma at 3.0T MRI

Objective To evaluate the clinic value and advantage of magnetic resonance imaging in the diagnosis of Hilar Cholangiocarcinoma at 3.0T MR. Methods To collect 26 cases 3.0T MRI and MRCP imaging data and Ultrasound diagonosis of hilar cholangiocarcinoma confirmed by clinical surgery and pathology, 12 of them had 3D-VIBE dynamic contrast-enhanced scanning, 10 conventional CT examination, compared with the pathological results so as to compare the clinic value of them. Results The accuracy of plain MR scan com...
