Forty-six patients, including 33 with proved pancreatic carcinoma, were studied with computerized tomography (CT), ultrasound (US), and radionuclide (RN) scanning. The results of each scanning procedure were compared with the surgical and clinical findings. The detection rate was 82% for CT, and 92% with US. A mass is the most important finding in the diagnosis of pancreatic carcinoma. Measurements of the pancreas with CT and US were similar, with visualization of all parts of the pancreas routinely better with CT scans. Radionuclide scans were abnormal in 96% of the patients with pancreatic carcinoma as well as in 75% of patients without pancreatic disease. A rational approach to examination of a patient with suspected pancreatic carcinoma should begin with US scan with available, because the detection rate with this method is equal to that with CT and its cost per procedure and for equipment is substantially less.
对46例患者进行了计算机断层扫描（CT）、超声（US）和放射性核素（RN）扫描研究，其中包括33例已证实患有胰腺癌的患者。将每种扫描方法的结果与手术及临床检查结果进行了比较。CT的检测率为82%，US的检测率为92%。肿块是胰腺癌诊断中最重要的发现。CT和US对胰腺的测量结果相似，CT扫描通常能更好地显示胰腺的各个部位。96%的胰腺癌患者以及75%无胰腺疾病的患者放射性核素扫描结果异常。对于疑似胰腺癌患者的检查，合理的方法应首先进行US扫描，因为这种方法的检测率与CT相当，且每次检查及设备成本要低得多。
