目的：探究磁共振成像技术（ MRI）与CT扫描检查辅助判断肾癌内出血的准确率与可行性。方法回顾性分析2005年9月—2013年1月垫江县中医院泌尿外科收治的89例肾癌患者的临床资料。术前51例患者行螺旋CT扫描检查，38例行MRI检查，以手术切除标本的病理检查结果作为诊断的金标准。结果 CT与MRI扫描检出肿瘤内出血灶的灵敏度分别为37．7％、97．1％，特异度分别为66．7％、33．3％。相关样本t检验结果显示，MRI扫描检出肾癌内出血病灶阳性率明显高于CT扫描（t＝8．12，P＝0．004）。结论 MRI扫描检出肾癌内出血阳性率灵敏度较高，可以作为临床医师术前判断患者预后的另一个主要手段。

Objective To evaluate the accuracy and feasibility of CT and MRI scanning on determination of hemorrhage in kidney carci-nomas.Methods A retrospective review on the clinical data of 89 patients who were admitted to hospital for renal cell carcinomas and received treatment during September 2005 to January 2013.51 patients underwent CT scanning,and 38 cases underwent MRI scanning. Results of histopathological test were considered as the golden standard.Results The sensitivities of CT and MRI scanning in detecting hemorrhage in renal cell carcinomas were 37.7%and 97.1%,respectively; and specificities were 66.7% and 33.3%,respectively. Results of the correlated samples t test showed that MRI scanning had a significantly higher positive rate in evaluating hemorrhage of re-nal cell carcinomas than CT examinations.Conclusion MRI is one of the means to detect hemorrhagic lesions in patients with kidney cancer,which is helpful for evaluating its prognosis.
