目的 探讨多排螺旋CT曲面重建在胰腺及胰周病变中的应用价值。方法 对胰腺和胰周病变的患者共 17例采用多排螺旋CT扫描上腹部 (5例单纯平扫 ,11例平扫 +增强 ,1例行静脉CT胆道造影 ) ,其中胰腺癌 4例 ,胆总管结石 3例 ,慢性胰腺炎伴假性囊肿 3例 ,真性囊肿合并慢性胰腺炎及胆道梗阻 1例 ,囊腺瘤 1例 ,胰岛细胞瘤 1例 ,胰周淋巴结肿大 3例和 1例脾动脉瘤。由操作者经特定的解剖结构和病变画线做曲面重建。结果 多排螺旋CT可获得高质量的曲面重建图像 ,跟踪显示胰胆管或胰周血管 ,和清晰显示病灶与胰腺、胰胆管和胰周血管的关系。结论 多排螺旋CT薄层扫描能获得胰腺高质量曲面图像 ,提供独特的解剖信息和相关病理征象 ,有助于胰腺和胰周病变的诊断及局部侵犯的评价 ,指导临床治疗方案的选择与实施。
Objective To investigate the value of multi-slice spiral CT reconstruction in the pancreas and peripancreatic lesions. Methods A total of 17 patients with pancreas and peripancreatic lesions were examined by multislice CT scan of the upper abdomen (5 cases of simple plain scan, 11 cases of plain scan + enhanced and 1 case of venous CT cholangiography), including 4 cases of pancreatic cancer, Common duct stones in 3 cases, 3 cases of chronic pancreatitis with pseudocysts, 3 cases of true cyst with chronic pancreatitis and biliary obstruction, 1 case of cystadenoma, 1 case of islet cell tumor, 3 cases of pancreatic lymph node enlargement and 1 case of spleen Aneurysm. By the operator through a specific anatomy and lesion drawing surface reconstruction. Results Multi-slice spiral CT can obtain high-quality surface reconstruction images, tracking the pancreatic duct or peripancreatic vessels, and clearly showing the relationship between the lesion and the pancreas, pancreatic duct and peripancreatic vessels. Conclusions Multi-slice spiral CT scan can obtain high-quality images of the pancreas, provide unique anatomical information and relevant pathological signs, contribute to the diagnosis of pancreatic and peripancreatic lesions and evaluate the local invasion, and guide the selection and implementation of clinical treatment options .
