摘要
目的:探讨多层螺旋CT(MSCT)在肾上腺肿瘤及肿瘤样病变中的诊断价值及其临床意义。方法:收集经临床保守治疗或手术病理证实的肾上腺肿瘤及肿瘤样病变24例,进行多层螺旋CT检查及三维重建,后处理技术包括薄层重建、多平面重组(MPR)、容积重组(VR)及最大密度投影(MIP),并进行回顾性分析。结果:24例肾上腺占位病变中,肾上腺增生7例,腺瘤6例,髓样脂肪瘤2例,肾上腺囊肿3例,嗜铬细胞瘤1例,肾上腺转移癌5例。肾上腺良性病变直径多小于3 cm,边界清晰。三维重建图像能清晰显示肾上腺肿瘤及肿瘤样病变的细微结构并能比较准确地对肾上腺肿瘤及肿瘤样病变作出诊断。结论:多层螺旋CT图像质量好,对肾上腺肿瘤及肿瘤样病变的综合判断能力较强,具有较好的应用价值。
Objective:To investigate the value and clinical significance of multi-slice spiral CT(MSCT)in the diagnosis of adrenal tumors and tumor-like lesions.Method:24 cases with surgically pathologically or clinical confirmed adrenal tumors and tumor-like lesions were examined with multislice spiral CT and 3D reconstruction and retrospectively analyzed.Post-processing techniques included thin-layer reformation,multiplanar reformation(MPR),volume reformation(VR)and maximum intensity projection(MIP).Result:Among 24 patients,adrenal hyperplasia was found in 7 cases,adenoma in 6 cases,myelolipoma in 2 cases,endothelial cysts in 3 cases,pheochromocytoma in 1 case,and metastatic tumors in 5 cases.The diameter of most benign lesions was less than 3 cm.3D photograph showed clearly the type and the micro-structure of adrenal tumors and tumor-like lesions.Conclusion:The quality of MSCT images is excellent,and MSCT can evaluate causes of benign and malignant the adrenal tumors and tumor-like lesions and should be widely applied.
