【摘要】 目的 :探讨多层螺旋CT(MSCT)扫描技术在肾移植患者中的应用。方法 :采用MarconiMX 80 0 0MSCT扫描仪对 2 7例肾移植术后患者进行下腹部螺旋扫描。扫描条件为 12 0kV、2 2 0mAs。平扫 :每圈螺层 4层 ,周旋时间 0 .5s ,层厚 3 .2mm ,重建层距 1.6mm ,螺距 1.2 5。扫描长度总层数 2 0 0～ 3 0 0。要求扫描野包括位于髂窝内的移植肾 ,肾动静脉及其与髂内外动脉、髂外静脉吻合处、输尿管及其与膀胱吻合处。增强扫描 :以 3ml/s流率经肘静脉注射 60 %欧乃派克 60～10 0ml。于注射开始后 2 2s(延时 )、70s行下腹部扫描 ,范围和方法同平扫 ,要求分期显示肾动脉、肾皮质、肾实质、肾静脉以及肾盂、输尿管。结果 :2 7例肾移植术后均清楚显示移植肾矢状位、冠状位图像、多层面图像、3D和 4D立体图像、CT血管造影图像、血管和肾盂输尿管图像等。 4例为阳性结果。阳性病种包括 :移植肾包膜下积液 1例 ,移植肾、输尿管中度积水 3例 ,原因为输尿管膀胱吻合处狭窄 ,做了探查 +输尿管膀胱吻合处狭窄切除及再吻合术。结论 :MSCT扫描技术为肾移植检查带来方便和直观的矢状位、冠状位图像、多层面图像、3D和 4D立体图像、CT血管造影图像、血管和肾盂输尿管图像等 ,对评价手术疗效有积极意义更多还原

【Abstract】 Objective:To evaluate the clinical application of multi row spiral CT in patients with kidney transplantation.Methods:27 cases with kidney transplantation were examined with Marconi MX 8000 multi slice spiral CT. All images with thin collimation and overlapping reconstruction were transferred to workstation.Results:27 patients were studied.All patients displayed clearly the transplant on sigittal and coronal images.Three dimensional and four dimensional images were reconstructed,using the shaded surface display (SSD) and maximum intensity projection (MIP).Multi row spiral CT scanning revealed abnormal findings in 4 patients,moderate dilatation of the renal pelvis in 3,and subcapsular fluid collection of the transplant in 1.Ureteral stenosis were diagnosed in 3 cases and consequently surgically treated.Conclusion:Multi row spiral CT can be used as a noninvasive technique for evaluation of effectiveness and complication of renal transplantation in cases with suspicion of operation complication.更多还原
