The anatomy of the portal vein branches in the caudate lobe of the liver was studied in 20 patients by double-phase CT arterial portography (DP-CTAP). DP-CTAP provided excellent images of the portal venous system in the first phase and the perfusion defects of intrahepatic tumors in the second phase. From DP-CTAP images of the first phase, a sufficient number of interpolated images were created for a smooth paging display. The ramifying structures of the portal system were traced on the monitor using the tracking ball. This method was found to be very effective and reliable for the anatomical assessment of the caudate lobe. The number and origins of the caudal portal branches were investigated in each case, and the caudate lobe of the liver could be divided into right and left segments.
通过双期CT动脉门静脉造影（DP-CTAP）对20例患者肝脏尾状叶门静脉分支的解剖结构进行了研究。DP-CTAP在第一期提供了门静脉系统的优质图像，在第二期提供了肝内肿瘤的灌注缺损图像。从第一期的DP-CTAP图像中，创建了足够数量的插值图像以实现平滑分页显示。使用跟踪球在监视器上追踪门静脉系统的分支结构。发现该方法对于尾状叶的解剖学评估非常有效且可靠。在每种情况下都对尾侧门静脉分支的数量和起源进行了研究，肝脏尾状叶可分为右段和左段。
