作者对178例可能供肾者作了螺旋CT动脉成象评价,男75例,女103例,年龄20～62岁。用连续横断面通过肾的平扫以确定兴趣区,并评价双肾存在、异常的肾和血管钙化。然后以4ml/s静脉注射150ml非离子型对比剂,在开始注射后14～20s,从肾上方至主动脉分叉下3cm,以层厚3mm、螺距1.5～1.8.进行螺旋扫描。再以7mm层厚完成腹部和盆腔扫描以评价肾实质肿块,并获得延迟腹部影像观察输尿管和膀胱。将螺旋CT影像进行1mm厚
The authors of 178 cases of possible donor kidney made by spiral CT arterial imaging, 75 males and 103 females, aged 20 to 62 years. Regions of interest were identified by continuous cross-sectional plain scanning of the kidneys and evaluated for the presence of both kidneys, abnormal renal and vascular calcifications. Then 4ml / s intravenous injection of 150ml of non-ionic contrast agent, 14 ~ 20s after the start of injection, from the top of the kidney to the aortic bifurcation 3cm, the thickness of 3mm, pitch 1.5 ~ 1.8. Helical scanning. Abdominal and pelvic scans were also completed at a 7 mm layer thickness to assess renal parenchymal masses and delayed abdominal imaging to visualize the ureter and bladder. Spiral CT images were 1mm thick
