Computerized tomography (CT) is a noninvasive indirect method of instrumental investigation for imaging the liver, bile ducts and the adjacent organs. CT enables one to confirm objectively the mechanical nature of jaundice, to assess a degree and level of involvement of the biliary tract, to assess the nature and spreading of disease. CT sensitivity for the diagnosis of pancreatic head cancer was 78.8%, specificity-91.3%, that for choledocholithiasis--84.6%, specificity--96.7%. CT in jaundice made it possible to establish diagnosis at various levels of accuracy: from differentiation of mechanical and parenchymatous jaundices to preliminary assessment of malignant tumor resectability facilitating a choice of surgical tactics.
计算机断层扫描（CT）是一种用于肝脏、胆管及相邻器官成像的无创间接仪器检查方法。CT能够客观地证实黄疸的机械性本质，评估胆道受累的程度和水平，评估疾病的性质和扩散情况。CT对胰头癌的诊断敏感性为78.8%，特异性为91.3%；对胆总管结石的诊断敏感性为84.6%，特异性为96.7%。CT用于黄疸检查时，能够在不同准确程度上做出诊断：从区分机械性黄疸和实质性黄疸，到初步评估恶性肿瘤的可切除性，从而有助于选择手术策略。
