We have evaluated ultrasound, computed tomography and arteriographic findings in 15 patients with 17 endocrine pancreatic tumours having a mean diameter of 2.3 cm (range 1-7 cm). All patients under-went computed tomography, and all but one ultrasound and arteriography. Ultrasound was the initial investigation in 11 patients, and identified 10 of the 16 tumours present in 14 patients. Two tumours were found at ultrasound reexamination after having been identified by other radiological methods. Computed tomography revealed 8 out of 17 tumours, while arteriography identified 8 out of 16 tumours. Computed tomography was the initial investigation in 4 patients, and identified one tumour. In only 4 patients were tumours not detected by any of the imaging methods. The sensitivities of ultrasound, computed tomography and arteriography in the detection of pancreatic tumours were 62.5% (95% confidence interval 50.4-74.6%), 47.1% (95% confidence interval 35.0-59.2%), and 50.0% (95% confidence interval 37.5-62.5%), respectively. Ultrasound was thus more accurate than computed tomography or arteriography in detecting endocrine pancreatic tumours, and should be the initial radiological investigation.
我们评估了15例患有17个内分泌胰腺肿瘤患者的超声、计算机断层扫描和动脉造影检查结果，这些肿瘤平均直径为2.3厘米（范围1 - 7厘米）。所有患者均接受了计算机断层扫描，除1例患者外，其余患者均接受了超声和动脉造影检查。超声是11例患者的初始检查方法，在14例患者中存在的16个肿瘤中，超声发现了10个。有2个肿瘤在通过其他放射学方法确诊后，经超声复查才被发现。计算机断层扫描显示17个肿瘤中的8个，动脉造影显示16个肿瘤中的8个。计算机断层扫描是4例患者的初始检查方法，发现了1个肿瘤。只有4例患者的肿瘤未被任何一种成像方法检测到。超声、计算机断层扫描和动脉造影检测胰腺肿瘤的敏感性分别为62.5%（95%置信区间50.4 - 74.6%）、47.1%（95%置信区间35.0 - 59.2%）和50.0%（95%置信区间37.5 - 62.5%）。因此，在检测内分泌胰腺肿瘤方面，超声比计算机断层扫描或动脉造影更准确，应作为初始放射学检查方法。
