To investigate the accuracy of dedicated pancreatic multidetector computed tomography (MDCT) in the diagnosis of neuroendocrine pancreaticoduodenal tumors (NPTs).
MDCT and other imaging studies in patients with suspected NPTs were identified. Thirty dedicated MDCT studies were done in 23 patients. Fourteen patients (16 operations) subsequently had surgery. Imaging reports were reviewed and findings compared with surgical findings and findings in other imaging studies.
Patients with surgery: 19 NPTs (16 extrapancreatic gastrinomas and 3 pancreatic NPTs) were identified at surgery. MDCT identified 16 and somatostatin receptor scintigraphy (SRS) 11 out of 19 tumors. Endoscopic ultrasound detected 11 out of 14 NPTs. Patients without surgery: In 4 out of 9 patients, no NPTs were identified at MDCT.
Dedicated MDCT of the pancreas can identify many NPTs, including small duodenal and periduodenal tumors, and the detection rate is better than reported in the older literature on CT.
探讨胰腺专用多层螺旋计算机断层扫描（MDCT）诊断神经内分泌性胰十二指肠肿瘤（NPTs）的准确性。
确定疑似NPTs患者的MDCT及其他影像学检查。对23例患者进行了30次胰腺专用MDCT检查。14例患者（16次手术）随后接受了手术。回顾影像学报告，并将检查结果与手术结果及其他影像学检查结果进行比较。
接受手术的患者：手术中发现19例NPTs（16例胰外胃泌素瘤和3例胰腺NPTs）。MDCT发现了19个肿瘤中的16个，生长抑素受体闪烁扫描（SRS）发现了11个。内镜超声检测到14个NPTs中的11个。未接受手术的患者：9例患者中有4例在MDCT上未发现NPTs。
胰腺专用MDCT能够识别许多NPTs，包括十二指肠和十二指肠周围的小肿瘤，其检出率优于早期CT文献报道。
