A critical "blind" evaluation of 129 randomly selected angiographic examinations was carried out including 37 control patients, 58 patients affected by proven chronic relapsing pancreatitis and 34 patients with cancer of the pancreas. In 48.5% of the control patients a completely normal angiographic picture was found. The false positives were found in 10.8% of chronic pancreatitis and in pancreatic carcinoma in 5.5% of the cases. Equivocal signs were found in 35.2%. The percentage of the false negative results in chronic pancreatitis was 34.4% (of which 8.6% were suggestive of pancreatic cancer). In pancreatic cancer positive results were seen in 70.6% of the cases. The percentage of the false negatives was 26.5% (suggestive of chronic pancreatitis); equivocal signs were found in 2.9% of these patients. Notwithstanding the not-negligible percentage of errors, angiography can be usefully employed in diagnosis of pancreatic disorders.
对129例随机选择的血管造影检查进行了严格的“盲法”评估，其中包括37例对照患者、58例经证实患有慢性复发性胰腺炎的患者和34例胰腺癌患者。在48.5%的对照患者中，血管造影图像完全正常。慢性胰腺炎患者的假阳性率为10.8%，胰腺癌患者的假阳性率为5.5%。可疑征象的比例为35.2%。慢性胰腺炎的假阴性结果比例为34.4%（其中8.6%提示胰腺癌）。胰腺癌患者的阳性结果比例为70.6%。假阴性比例为26.5%（提示慢性胰腺炎）；这些患者中有2.9%存在可疑征象。尽管错误比例不可忽视，但血管造影在胰腺疾病的诊断中仍可有效应用。
