本文回顾性分析53例经手术病理证实的肾癌之影像学表现。介绍了肾癌的 CT 表现,统计了增强前后肾癌与正常肾实质的 CT 值变化。显示增强后肾癌组织 CT 值全部低于正常肾实质。指出对怀疑肾占位患者必需作 CT 增强检查。文章对肾癌按 Robson 分期进行了 CT 影像分析并与手术病理结果作了比较,其符合率为86%。对不符合的6例分析了分期错误的原因,还比较了 CT 和血管造影的关系;评价了 MRI 对肾癌的诊断价值,认为 MRI 并不适宜作为肾占位或肾癌检查的首选影像学工具。
This retrospective analysis of 53 cases of pathologically confirmed renal cell carcinoma imaging findings. The CT features of renal cell carcinoma were introduced. The changes of CT value of renal cell carcinoma and normal renal parenchyma before and after the enhancement were analyzed. The results showed that CT value of renal cell carcinoma was lower than that of normal renal parenchyma. Pointed out that the need for CT-enhanced examination of patients suspected of having a kidney. According to Robson’s staging of renal cell carcinoma, CT images were compared with the results of surgical pathology, the coincidence rate was 86%. 6 patients who did not meet the analysis of the reasons for staging errors, but also compared the CT and angiography; Evaluation of the diagnostic value of MRI on renal cell carcinoma, that MRI is not suitable as a renal imaging or renal imaging examination of choice tool.
