The present study aimed to describe the characteristics of cystic pancreatic tumors using computed tomography (CT) and to evaluate the diagnostic accuracy (DA) of post-imaging three-dimensional (3D) reconstruction. Clinical and imaging data, including multi-slice spiral CT scans, enhanced scans and multi-faceted reconstruction, from 30 patients with pathologically confirmed cystic pancreatic tumors diagnosed at the Linyi People's Hospital between August 2008 and June 2014 were retrospectively analyzed. Following the injection of Ultravist® 300 contrast agent, arterial, portal venous and parenchymal phase scans were obtained at 28, 60 and 150 sec, respectively, and 3D reconstructions of the CT images were generated. The average age of the patients was 38.4 years (range, 16-77 years), and the cohort included 5 males and 25 females (ratio, 1:5). The patients included 8 cases of mucinous cystadenoma (DA), 80%]; 9 cases of cystadenocarcinoma (DA, 84%); 6 cases of serous cystadenoma (DA, 100%); 3 cases of solid pseudopapillary tumor (DA, 100%); and 4 cases of intraductal papillary mucinous neoplasm (DA, 100%). 3D reconstructions of CT images were generated and, in the 4 cases of intraductal papillary mucinous neoplasm, the tumor was connected to the main pancreatic duct and multiple mural nodules were detected in one of these cases. The DA of the 3D-reconstructed images of cystic pancreatic tumors was 89.3%. The 64-slice spiral CT and 3D-reconstructed CT images facilitated the visualization of cystic pancreatic tumor characteristics, in particular the connections between the tumor and the main pancreatic duct. In conclusion, the 3D reconstruction of multi-slice CT data may provide an important source of information for the surgical team, in combination with the available clinical data.
本研究旨在利用计算机断层扫描（CT）描述胰腺囊性肿瘤的特征，并评估成像后三维（3D）重建的诊断准确性（DA）。回顾性分析了2008年8月至2014年6月在临沂市人民医院确诊的30例经病理证实的胰腺囊性肿瘤患者的临床和影像数据，包括多层螺旋CT扫描、增强扫描和多平面重建。注射优维显®300造影剂后，分别在28秒、60秒和150秒获得动脉期、门静脉期和实质期扫描，并生成CT图像的3D重建。患者的平均年龄为38.4岁（范围16 - 77岁），该队列包括5名男性和25名女性（比例为1:5）。患者包括8例黏液性囊腺瘤（诊断准确性，80%）；9例囊腺癌（诊断准确性，84%）；6例浆液性囊腺瘤（诊断准确性，100%）；3例实性假乳头状瘤（诊断准确性，100%）；4例导管内乳头状黏液性肿瘤（诊断准确性，100%）。生成了CT图像的3D重建，在4例导管内乳头状黏液性肿瘤中，肿瘤与主胰管相连，其中1例检测到多个壁结节。胰腺囊性肿瘤3D重建图像的诊断准确性为89.3%。64层螺旋CT和3D重建CT图像有助于观察胰腺囊性肿瘤的特征，特别是肿瘤与主胰管之间的连接。总之，多层CT数据的3D重建结合现有的临床数据可为手术团队提供重要的信息来源。
