摘要
目的:探讨16层CT显示副肾动脉及临床应用价值。材料和方法:对300例中腹部扫描病例采用16层螺旋CT增强扫描,对获得的所有肾动脉原始图像,结合多平面重建(MPR)、最大密度投影(MIP)和容积显示(VR)进行统计、分析。结果:本组副肾动脉发生率为25.9%,左、右侧分别为24.3%、27.3%,其中1支及2支副动脉发生率分别为24.2%(右25%,左23.3%)、1.7%(右2.3%,左1.0%);男、女分别为27.8%、23.5%,它们之间均无显著性差异。1支及2支副肾动脉平均直径分别为2.5mm、2.2mm(右)和2.4mm、2.1mm(左)。结论:16层螺旋CT在显示副肾动脉方面可提供较详细的信息,可应用于外科肾脏手术、介入治疗及肾移植供肾术前的评价。
To investigate additional renal arteries with 16 slice spiral CT and evaluate their value of clinical application. Materials and Methods： Three hundred cases of mid - abdomen enhancement scanning were taken with 16 - slice spiral CT. All initial images of renal arteries and their reconstructive images of renal arteries in volume rendering（VR）, multiplanar reconstruction（MPR） and maximum intensity projection（MIP） were observed. Results： In all, the incidence of additional renal arteries was 25.9% （R 27.3%, L 24.3% ） . Incidence of one and two additional arteries were 24.2% （R 25.0%, L 23.596） and 1. 796 （R 2. 396, L 1. 096） respectively, and were 26. 996, 0.996 in males, 21. 096, 2.596 in females respectively. These differences were no statistically significant. Conclusion： More information was provided about additional renal arteries with 16- slice spiral CT , which may be useful in evaluating the kidneys and the supplying arteries related with surgery, intervention and renal transplantation.
