目的 探讨多层螺旋CT在肾癌中 的诊断价值。方法 以64例经手术病理证 实的肾癌患者作为研究对象，根据其临床 资料进行回顾性分析和总结，分析多层 螺旋CT在肾癌中的诊断价值。结果 CT平 扫表现为稍高密度者6例，混杂密度者19 例，等密度或稍低密度者23例；CT增强扫 描肿瘤明显强化者39例，中度不规则强化 者17例，轻度强化者8例，三期增强扫描 表现为快进快退的强化特点。螺旋CT分 期I期40例，II期6例，III期8例，IV期9 例，与病理分期比较，差异无统计学意义 (P＞0.05)。结论 多层螺旋CT在肾癌中的 诊断价值较高，其影像具有一定的特征 性，可提高对肾癌的诊断准确性和分期能 力，为临床制定治疗方案及评估预后提供 重要的信息，值得推广。

Objective To investigate diagnostic value of multi-slice spiral CT in renal carcinoma. Methods Sixty four patients confirmed to suffer from kidney cancer by surgery pathology research object, retrospective analysis and summary were made according to the clinical data were, and diagnostic value of multi-slice spiral CT in renal carcinoma were analyzed. Results CT plain scan demonstrated there were 6 patients with high density, 19 patients with mixed density, and 23 patients with isodensity or slightly low density. CT enhanced scan showed that there 39 patients with significantly reinforced tumor, 17 patients with moderate irregularly reinforced tumor and 8 patients with mildly reinforced tumor, and enhanced scan of three phases showed fast forward reinforced characteristics of fast forward and quick backward. Spiral CT staging involved 40 patients at Stage I, 6 patients at Stage II, 8 patients at Stage III, 9 and patients at Stage IV, and the difference was no statistically significant when compared to that of pathological staging (P＞0.05). Conclusion Multi-slice spiral CT delivers high diagnostic value in renal carcinoma, its images show certain characteristics, it can improve the accuracy of diagnosis and staging ability of renal carcinoma, and it provides important information for clinical development of therapeutic schedule and prognosis evaluation, being worthy of popularization.
