Thirteen patients with resectable pancreatic carcinoma were examined by computed tomography (CT). Nine had a mass, 2 had dilatation of the main pancreatic duct, 1 appeared to have ductal dilatation, and 1 had no sign of abnormality. Resectable carcinoma was diagnosed retrospectively in 8 cases, based on the following criteria: a mass with a distinct contour, frequently containing a tiny or irregular low-density area and accompanied by dilatation of the caudal portion of the main pancreatic duct without involvement of the large vessels, liver, or lymph nodes. Including unresectable cancer, chronic pancreatitis, and obstructive jaundice from causes other than cancer, the false-positive rate was less than 6%. However, a small cancer without change in pancreatic contour is difficult to detect with CT.
对13例可切除胰腺癌患者进行了计算机断层扫描（CT）检查。9例有肿块，2例主胰管扩张，1例似乎有导管扩张，1例无异常迹象。根据以下标准，8例患者被回顾性诊断为可切除癌：肿块轮廓清晰，常含有微小或不规则低密度区，并伴有主胰管尾部扩张，无大血管、肝脏或淋巴结受累。包括不可切除癌、慢性胰腺炎和非癌性原因引起的梗阻性黄疸，假阳性率低于6%。然而，CT很难检测到胰腺轮廓无变化的小癌。
