The Diagnostic Value and Type of Multi-slice Spiral CT Reconstruction in Small Renal Carcinomas
-
摘要: 目的: 根据CT扫描图像及三维重建表现,探讨多层螺旋CT扫描对小肾癌的诊断及鉴别诊断的价值,并对小肾癌进行分型。资料与方法: 收集行多层螺旋CT扫描并经临床病理证实的43例小肾癌病例资料,就其CT表现进行分析并进行分型。结果: 凸出型小肾癌23例,CT表现为肿瘤凸向肾轮廓之外或凸向肾盂、肾盏,增强扫描时,肿瘤内部造影剂呈明显快进快出的典型恶性肿瘤表现;肾实质内型小肾癌6例,CT表现为肿瘤位于肾实质之内,增强扫描肿瘤呈典型肾癌强化特征;囊性型小肾癌9例,CT表现为肿瘤内部有多发纤维索条状或小片状强化,且强化程度较明显;多发型小肾癌5例,CT表现为一侧肾脏出现多个小肾癌。结论: 多层螺旋CT扫描结合三维重建图像后处理技术能够准确、有效地诊断各种类型的小肾癌。Abstract: Objective: According to the CT scan image and the performance of three-dimensional reconstruction,to study the diagnostic value and type of MSCT reconstruction in small renal carcinomas.Materials and Methods: A retrospective analysis was done for 43 cases of small renal carcinomas which received MSCT examination and confirmed by pathology in our hospital,analysis and type them with their performance in the CT examination.Results: There are 16 cases of small renal carcinoma of protruding type,their performance of CT examination are the tumors convex to the outline of the kidney or convex to the renal pelvis or calyx,when in enhancement CT scan,the contrast agent in the tumor are fast flowing in and fast flowing out which are the performance of malignant tumor;There are 6 cases of small renal carcinoma of inside renal parenchyma type,their performance of CT examination are the tumors limited in the renal parenchyma,when in enhancement CT scan,the performance of the tumor are f the typical performance of malignant tumor;There are 9 cases of small renal carcinoma of cystic type,their performance of CT examination are that when in enhancement CT scan,there are multiple enhanced uneven thickness stripes or small pitchy enhancement in the tumor;There are 5 cases of small renal carcinoma of multiple type,their performance of CT examination are that there are multiple small renal carcinomas in one kidney.Conclusion: Multi-slice spiral CT scan with 3D reconstruction image post-processing techniques can accurately and effectively diagnose various types of small renal carcinoma.
