Abstract

Dynamic MRI with injection of Gd-DTPA was performed in 7 patients with hepatocellular carcinoma associated with portal vein tumor thrombus. A portal vein tumor thrombus was clearly visualized as a low intense structure. The segment supplied with this portal vein shows high intensity, probably due to the decrease in portal blood flow and compensated arterial blood flow. A tumor itself, located in this segment, was shown as a low intense area. Thus dynamic MRI is a useful method for differentiating the tumor from the surrounding nontumorous tissue with decrease in portal flow.

摘要

对7例伴有门静脉癌栓的肝细胞癌患者进行了注射钆喷酸葡胺的动态磁共振成像检查。门静脉癌栓清晰显示为低强度结构。由该门静脉供血的节段显示为高强度，这可能是由于门静脉血流减少和动脉血流代偿所致。位于该节段的肿瘤本身显示为低强度区域。因此，动态磁共振成像是一种有助于在门静脉血流减少的情况下区分肿瘤与周围非肿瘤组织的有用方法。
