摘　　要：目的:探讨肾盂移行上皮细胞癌MRI特点。方法:回顾性分析经手术和病理证实的26例肾盂移行上皮细胞癌MRI表现。结果:肿瘤位于肾盂19例,位于肾盏7例。MR信号在T2WI上为均匀略高信号15例,混杂等高信号8例,均匀等信号2例,等低信号1例;在T1WI上为均匀低信号16例,混杂信号8例,均匀等信号2例;增强18例中10例轻度均匀强化,8例轻度不均匀强化。MRI明确诊断肾盂移行上皮细胞癌18例,可疑肾盂移行上皮细胞癌5例,误诊2例,漏诊1例。结论:MRI对肾盂移行上皮细胞癌病灶的发现,观察生长方式和侵犯范围均具有较高价值。Objective：To study the MRI features of transitional cell carcinoma （TCC） of renal pelvis. Methods：The MRI findings of surgery and pathology proved TCC of renal pelvis in 26 cases were retrospectively analyzed. Results：The location of tumors were in the renal pelvis （19 patients） and renal calices （7 patients）. 15 tumors showed homogeneous slight hyperintensity and 8 tumors showed heterogeneous hyper intensity,2 tumors showed homogenous iso-intensity and i tumor showed homogeneous hypo intensity on T2WI. Homogeneous hypo intensity （16 tumors）, heterogeneous signal intensities （2 tumors） and homogeneous iso-intensity （2 tumors） were showed on T1 WI. Enhanced scans were performed in 18 patients with 10 tumors were slightly homogeneously enhanced and 8 tumors were slightly heterogeneously enhanced. MRI provided accurate diagnosis of TCC of renal pelvis in 18 patients,with 5 patients were suspected of TCC in renal pelvis;2 cases were misdiagnosed and 1 case was missed by MRI. Conclusion： MRI is helpful in the detection, understanding of growth pattern and invasion extent of transitional cell carcinoma of renal pelvis.
