多层螺旋CT三维重建技术对泌尿系疾病的诊断价值

目的探讨多层螺旋CT三维重建技术在泌尿系疾病中的应用价值。方法对42例(正常肾9例,正常输尿管5例,泌尿系疾病28例)泌尿系患者行双层螺旋CT扫描后均采用三维重建技术对横断面图像进行重建。结果根据疾病和诊断目的的不同采用不同的重建方法进行重建。最大强度投影(MIP)图像对肾动脉狭窄及全尿路显示有很好效果,多断面重建(MPR)图像可用于显示各种占位病变的位置、大小、范围等,SSD和VRT图像适用于显示肾脏畸形、肾脏肿块、肾结石和输尿管变异等。结论对于不同的泌尿系疾病采用不同的三维重建方法对疾病的诊断有很大帮助。

Diagnosis value of 3-dimension reconstruction technique of multi-slice CT in the diseases of urinary system

Objective To investigate the clinical application value of three-dimensional(3D) reconstruction technique of multi-slice computed tomography (MSCT) in the disease of urinary system. Methods MSCT was performed in 42 patients- of which 9 was normal kidney-5 was normal ureter- 28 had urinary disease.All the axial images were reconstructed using 3D technique.Results Different recon-struction method should be used according to the type of disease and diagnostic purpose. MIP can display stenosis of renal artery and full view of the urinary system better. MPR can display the location- size- and range of focus.SSD and VRT are fit for display of the abnormality- mass- stones of kidney and anomaly of ureter.Conclusion It is helpful for the diagnoses of different disease to use different reconstruction method according to the type of disease of urinary system.
