长期作血液透析的病人可在终末期肾内发现获得性囊性肾病,透析时间愈长,发生率高,而在这些病人中肾细胞癌的发生率也可达5％～19％。由于多发性肾囊肿的肾结构的扭曲使肾细胞癌在常规CT上的诊断发生困难。作者对过去3年中630例作慢性血液透析的病人作了早期和延迟的增强和未增强螺旋CT扫描以评价螺旋CT在本组病人中对检出肾细胞癌的能力。以1.5～2ml/s速度团注对比剂 Long-term hemodialysis patients can be found in the terminal renal cystic nephropathy, dialysis longer, the high incidence of renal cell carcinoma in these patients the incidence of up to 5% to 19%. Due to the distortion of the renal structure of multiple renal cysts, the diagnosis of renal cell carcinoma on conventional CT is difficult. The authors made early and delayed enhancement and non-enhanced helical CT scans of 630 patients undergoing chronic hemodialysis over the past three years to assess the ability of spiral CT to detect renal cell carcinoma in this group of patients.
