A retrospective analysis was performed on 102 patients who were examined by both ultrasound (US) and computed tomography (CT) for known or possible carcinoma of the pancreas. In 38% of the patients, ultrasonography was unsatisfactory due to overlying interfering intestinal gas or ascites, whereas only 2% of CT studies were unsatisfactory due to technical considerations. In comparing the two modalities, CT was found to be more accurate (96% CT vs. 84% US), and this became more significant when nondiagnostic studies were considered in evaluating accuracy (95% CT vs. 54% US). Because of the findings in this analysis, CT is recommended as the initial diagnostic imaging modality for the evaluation of possible pancreatic neoplasm.
对102例已知或疑似胰腺癌患者进行了回顾性分析，这些患者均接受了超声（US）和计算机断层扫描（CT）检查。38%的患者因肠道气体或腹水干扰而导致超声检查结果不理想，而CT检查因技术问题导致结果不理想的仅占2%。比较这两种检查方式时，发现CT更准确（CT为96%，US为84%），在评估准确性时考虑非诊断性检查结果时，这种差异更为显著（CT为95%，US为54%）。基于本分析结果，建议将CT作为评估可能的胰腺肿瘤的初始诊断成像方式。
