目的 :根据肾癌的 CT表现 ,探讨 CT对肾癌诊断及鉴别诊断的价值。方法 :回顾性的分析了 54例经手术和 /或活检病理证实的肾癌病人的 CT资料 ,观察其 CT征象及分期。结果 :典型肾癌 CT表现为大小不等的肾脏肿块 ,等密度或略低密度占多数 ,为 4 9例 ,占 90 .74 % ;略高密度 5例 ,占 9.2 6% ,增强后肿瘤有不同程度强化 ,但其 CT值均明显低于正常肾实质。诊断正确率为 96.4 2 %。根据 Robson分期法 — 期各有 2 0 ,1 2 ,1 0 ,1 2例。结论 :CT可为肾癌早期诊断、准确分期、制定手术和治疗方案提供可靠依据
Objective: To evaluate the value of CT in the diagnosis and differential diagnosis of renal cell carcinoma based on the CT findings of renal cell carcinoma. Methods: CT data of 54 patients with renal cell carcinoma proved by operation and / or biopsy were analyzed retrospectively. Their CT signs and stages were observed. Results: The typical manifestations of renal cell carcinoma were renal masses of different sizes. The isodense or slightly lower density accounted for 49.7% (90.74%), slightly higher density in 5 cases (9.26%), and the enhanced tumors Varying degrees of enhancement, but the CT values were significantly lower than normal renal parenchyma. The correct diagnosis rate was 96.4 2%. According to Robson staging - each has 20, 12, 10, 12 cases. Conclusion: CT can provide a reliable basis for early diagnosis of renal cell carcinoma, accurate staging, operation and treatment planning
