摘　　要：目的探讨16层螺旋CT成像在活体肾移植供体术前评价中的价值。方法36例肾移植供体行16层CT平扫、动脉期、静脉期和排泄期检查。采用最大密度投影和容积再现技术处理图像，2位放射科医师独立评价每个供体血管和集尿系统的解剖结构。活体肾移植术中所见作为标准，计算16层CT评价肾血管和集尿系统的特异性和准确性。结果16层CT检查发现变异肾动脉7支，1支外科手术中确诊的副肾动脉被漏诊。16层CT检查正确诊断了外科手术发现的全部肾静脉和输尿管解剖变异，诊断。肾动脉、肾静脉和输尿管解剖变异的特异性为100％（29／29）、100％（32／32）和100％（35／35），准确性分别为97％（36／37）、100％（36／36）和100％（36／36）。结论16层CT检查评价活体移植肾的血管和集尿系统准确性较高，是一种很好的术前评价活体移植肾的无创性检查方法。Objective To analyze the clinical value of 16-row multislice CT in the live kidney donor preoperative assessment. Methods Thirty-six kidney donors underwent 16-slice CT preoperative assessment. The non-enhanced, arterial phase, venous phase and excretory phase examinations were performed. Two radiologists independently studied renal vessels and urinary system of each case by maximum intensity projections and volume rendering techniques. The specificity and accuracy of 16- row multislice CT in the evaluation of renal vessels and urinary system were calculated after comparing with surgical findings as reference. Results 16 row multislice CT found 7 variant renal arteries. One variant artery confirmed in surgery was missed in the CT study. 16 row multislice CT made correct diagnosis of all variant anatomy of renal veins and ureters which were confirmed in surgery. For identification of variant anatomy of renal arteries, veins and ureters, the specificity of 16 slice CT was 100% （29/29）, 100%（32/32）, and 100%（35/35）, the overall accuracy was 97%（36/37）, 100%（36/ 36）, and 100% （36/36）, respectively. Conclusions 16-row multislice CT shows excellent value in the evaluation of renal vessels and urinary system in live kidney donors. 16-row multislice CT is suit able for the noninvasive examination in live kidney donor preoperative assessment and provides all supportive and relevant information required by the surgeons.
