| 目的 探讨小胰腺癌的CT表现。方法 回顾性分析41例经手术病理证实的小胰腺癌的CT征象。结果 41例中肿瘤位于胰头颈部29例,钩突部10例,体部2例。肿瘤最大径在2.0~3.0cm者8例,1.0~2.0cm者30例,<1.0cm者3例。平扫肿瘤呈等密度或略低密度,增强后呈相对低密度。多数病例伴有不同程度的肝内外胆管扩张和胰管扩张及胰腺形态改变。结论 小胰腺癌在增强CT上表现为低密度,螺旋CT双期增强扫描较动态增强CT 扫描更有价值。 |

| Objective To study the CT signs of the small pancreatic carcinoma. Methods The CT data of the 41 cases of the small pancreatic carcinomas proved by surgical pathology were retrospectively analyzed. Results Twenty-nine of 41 cases were located in the heads or necks, 10 cases in the processus uncinatus, 2 cases in the bodies. The maximize size of 41 small pancreatic carcinomas were ranged from l.0cm to 3.0 cm. Twenty-six were presented as isodensity and l5 were low density on the unenhanced CT images. All of them showed low density with peripheral enhanced on the enhanced images. Most of them accompanied with dilation of intra-or extra-hepatic bile duct, pancreatic duct and deformed the contour of the pancreas. Conclusion The small pancreatic carcinomas were presented as low density on enhanced images, dual-phase enhanced spiral CT was more valuable than dynamic enhanced CT. |
