摘　　要：目的准确无创地检测肾静脉血栓(renal vein thrombosis,RVT)至关重要。文中以CT血管成像为参照标准,评价三维对比增强磁共振成像(three-dimensional contrast-enhanced magnetic resonance venography,3D-CE-MRV)诊断RVT的价值。方法 2010年12月到2012年3月,对32例肾病综合征患者进行了肾静脉的CT血管成像和3D-CE-MRV,时间间隔0～5 d。以患者和血管(左肾静脉、右肾静脉和下腔静脉)为分析单位分别记录RVT的有无。以CT血管成像的分析结果为参照标准,计算3D-CE-MRV检测RVT的敏感性和特异性。结果 32例患者中,CT血管成像共检测17例患者22条血管有RVT,包括右肾静脉5条、左肾静脉14条,下腔静脉3条。3D-CE-MRA检出16例患者21条血管有血栓,包括右肾静脉5条,左肾静脉13条,下腔静脉3条。以CT血管成像结果为参照标准,以患者和血管为分析单位,3D-CE-MRA检测RVT的敏感性和特异性分别为94.1%、100%,95.5%、100%。结论 3D-CE-MRA与CT血管成像在检测RVT方面有较高的价值,推荐在临床怀疑RVT时应用。Objective It is important to accurately and noninvasively detect renal vein thrombosis （RVT）. The purpose of this study was to evaluate the value of three-dimensional contrast-enhanced magnetic resonance venography （3D-CE-MRV） for detec- ting RVT with CT venography as reference standard. Methods Thirty two patients with nephrotic syndrome from December 2010 to March 2012 performed renal CT venogrpahy and 3D-CE-MRV with time interval of 0 to 5 days. RVT was recorded on a per-patient and per-vessel （ left renal vein, fight renal vein, and inferior vena cava） basis. The diagnostic sensitivity and specificity of 3D-CE-MRV for detection of renal vein thrombosis was calculated using CT venography outcome as reference standard. Results Of 32 patients, CT venography detected 22 vessels with thrombosis in 17 patients, including 5 right renal veins, 14 left renal veins, and 3 inferior vena ca- va. 3D-CE-MRA detected 21 vessels with thrombosis in 16 patients, including 5 right renal veins, 13 left renal veins, and 3 inferior vena cavas. With CT venography as reference standard, the sensitivities and specificities of 3D-CE-MRA for renal vein thrombosis de- tection were 94.1%, 100% ; 95.5%, 100% on a per-patient and a per-vessel basis; respectively. Conclusion 3D-CE-MRV has the high value in the detection of renal vein thrombosis, which should be recommended in clinical oractice.
