Medical imaging plays an essential role in the preoperative assessment of liver transplant patients to detect any lesions contraindicating the operation or to detect any anatomical variants in the recipient likely to lower the chances of success of the transplantation. At the present time, the imaging techniques useful in the preoperative assessment are colour Doppler ultrasound, abdominal CT scan and coeliac and superior mesenteric arteriography. The calibre and patency of the portal trunk and its branches, the hepatic artery at the porta hepatis, the hepatic veins and their distribution and the inferior vena cava are systematically evaluated. Systematic identification of the various portosystemic shunts in the context of portal hypertension helps to define a veritable preoperative map.
医学成像在肝移植患者的术前评估中起着至关重要的作用，以检测任何禁忌手术的病变，或检测受者中可能降低移植成功率的任何解剖变异。目前，术前评估中有用的成像技术是彩色多普勒超声、腹部CT扫描以及腹腔干和肠系膜上动脉造影。系统地评估门静脉主干及其分支、肝门处的肝动脉、肝静脉及其分布以及下腔静脉的管径和通畅情况。在门静脉高压的背景下系统地识别各种门体分流有助于绘制一张真正的术前图谱。
