【摘要】 目的:通过多层螺旋CT对正常成人肾筋膜和肾周间隙的观察和测量,探讨多层螺旋CT显示肾筋膜的附着及通连情况。方法:搜集在我院接受腹部CT增强扫描检查的健康成人资料97例,采用多层螺旋CT扫描对肾周间隙行多平面三维重组,测定肾筋膜的厚度,并观察肾筋膜的显示率以及肾筋膜向上和向下的通连情况。结果:肾筋膜在肾脏上、下极之间的显示率为100%,且双侧肾筋膜在MPR图像上的显示率大于轴面图像。左、右侧肾筋膜厚度分别为(0.13±0.02)cm和(0.12±0.02)cm,不同性别及年龄组别间筋膜厚度差异无统计学意义(P>0.05)。多层螺旋CT发现肾筋膜的附着及肾周间隙的通连情况具有不同类型:①双侧肾前、后筋膜向下融合,融合点位于髂前上棘以上2 cm至髂前上棘以下2 cm之间,并且由外而内逐渐降低,本组有95例,占97.9%;②双侧肾前、后筋膜向下间断融合,本组有2例,占2.1%。结论:多层螺旋CT及图像三维重建能较好的显示肾筋膜及其附着和肾周间隙的通连情况,为临床诊断提供科学依据。更多还原

【Abstract】 Objective:To measure the renal fascia and evaluate the anatomy of perirenal space and its communications and boundaries with multi-slice spiral CT(MSCT).Methods:MSCT scanning was performed in 97 normal subjects,and the multiplanar reconstruction(MPR) images of perirenal space and its anatomical communications were obtained on a postprocessing workstation.The shape,size and anatomical communications of the perirenal space were observed and measured.Results:Between the upper and lower pole of kidney,the detection rate of renal fascia was 100%.It was easier to visualize the renal fascia on MPR images than those on transverse CT images.The thickness of the left and right renal fascia was(0.13±0.02)cm and(0.12±0.02)cm,respectively.No significant difference in renal fascia thickness was found between different gender and age groups(all P>0.05).Different types of adhesion and anatomical communication of renal fascia were distinctly visualized on MSCT images.Conclusions:MSCT and MPR images could clearly visualize the morphologic features and anatomical communication of the perirenal space,which may be helpful in making diagnostic decisions.更多还原
