螺旋CT在肾癌诊断中的价值

Evaluation of spiral CT Scanning in the diagnosic of renal cell carcinoma

目的探讨螺旋CT在肾癌诊断中的价值。方法回顾性分析62例经手术病理证实的’肾癌的CT表现。结果肿瘤≤3cm9例，〉3cm53例，典型肾癌CT表现为大小不等的肾肿块，低密度及混杂密度占多数，为57例，占91．94％，等密度4例，占6．45％，稍高密度1例，占1．61％，增强扫描肿瘤有不同程度强化，强化程度均低于正常肾实质。结论螺旋CT是诊断肾癌最理想的影像工具。

Objective To evaluate the value of spiral CT scanning in the diagnesis of renal cell carcinoma. Methods The features of CT scan in 62cases of renal cell carcinoma proved by operation and pathology were analyzed retrospectively. Results Diameter of tumor≤3cm in 9 cases, 〉3cm in 53 cases. The typical CT scan features of renal cell carcinoma were renal tumor mass with different size. The most cases （57,91.94%） were low density or heterogeneous density, isdense mass in 4 cases（6.45%）, slightly hyperdense mass 1 case（1. 61%）.Different degree of intensification might be seen after enhancement, but the CT value was lower than that of the normal renal parenchyma. Conclusion Spiral CT is a very valuable method in diagnosis of renal cell carcinoma.
