64排CT增强扫描在胰尾脾门区病变诊断中的应用

Application of 64-detector CT-enhanced Scan in the Diagnosis of lesions of Pancreatic Tail and Splenic Hilum

目的:探讨64排CT增强扫描对胰尾脾门区病变诊断的价值。方法:回顾性分析52例胰尾脾门区占位性病变,所有病例均行64排CT平扫和增强扫描,运用不同的后处理技术,判别病变的起源和性质,总结不同起源病变对周围结构侵犯的特点。结果:胰腺肿瘤26例,胰腺炎9例,结肠脾曲癌8例,胃肿瘤5例,淋巴瘤2例,脾动脉瘤2例。胰尾脾门区肿瘤性病变41例,炎性病变9例,血管性病变2例。结论:胰尾脾门区病变侵犯结构复杂,鉴别诊断困难,64排CT增强扫描有利于病变定位定性诊断,为临床诊疗提供影像学依据。

Objective： To investigate the diagnostic value of 64-detector CT-enhanced scan in lesions of pancreatic tail and splenic hilum. Methods： Retrospective analysis of 52 cases with lesions of pancreatic tail and splenic hilum,undergoing64-detector plain and enhanced CT scan were performed. Different post-processing techniques were used to discriminate origin and nature of the lesions,and the characteristics of invasion around structure of different origin diseases were summarized. Results： There were 26 cases of pancreatic neoplasms,9 cases of pancreatitis,8 cases of splenic flexure of colon cancer,5 cases of gastric neoplasms,2 cases of lymphoma,2 cases of splenic artery aneurysm. Lesions of pancreatic tail and splenic hilum include 41 cases of tumors,9 cases of inflammatory lesion and 2 cases of vascular lesion. Conclusion： Invasion around structure of lesions of pancreatic tail and splenic hilum is complex,and diagnosis is difficult. The64-detector CT enhanced scan is favorable for lesion localization and qualitative diagnosis,thus providing imaging basis of clinical diagnosis and treatment.
