【摘要】 目的通过对正常活体肾脏在多层螺旋CT(MSCT)图像上一些指标的观测分析,提供相应的正常值范围为临床和教学服务。方法收集腹部多层螺旋CT扫描正常肾脏123例,并行三维成像,观察左、右侧肾脏上、下极平椎体的位置,并同时比较同一个体左、右侧肾脏的高低。测量左、右侧肾脏上、下端距脊柱中线的距离及长轴与短轴的长度;测量左、右侧肾脏长轴与矢状面(侧夹LS)及冠状面(前夹LC)的夹角;测量肾门中点至对应的肾脏外缘最突点的连线与冠状面的夹角(前倾CL),并进行统计学处理。结果左肾高于右肾的百分率明显大于右肾高于左肾的百分率。左、右肾上极大部分都平T12,左肾上极高于T11的例数较右肾多,双侧肾脏下极大部分都平L2下份至L3下份。左、右侧肾脏各CT测量指标的统计结果除男前倾、男前夹、女前夹、总前夹、总侧夹外,大部分左侧肾脏测量指标大于或接近于右侧,并且有男宽、总长、总宽、总上距具有显著统计学意义(P<0.05)。男性大部分测量指标都大于女性,并且男、女的侧夹角及上、下距具有显著统计学意义。结论本研究获得了正常活体肾脏的位置、大小、形态的数据,可供临床诊断、治疗以及教学时参考。更多还原

【Abstract】 Objective To observe and analyze the standards of the normal vivo renal multi-slice spiral CT(MSCT) imaging to provide relevant normal range for clinic and teaching.Methods 123 cases with normal kidneys were undergone abdominal MSCT,then 3D imaging was performed,the position of kidney distance between two poles of kidney and the central line of the spine,renal length and short axis,the angels between the renal length axis and sagittal segment(LS) and the coronal segment(LC),the angel between coronal segment and the longest distance line from the midpoint of the renal gate to the same kidney’s out edge(CL) were observed and measured with statistics analysis.Results Mostly the position of left kidney was higher than that of the right.Almost kidney’s upper poles located at the T12 level.The number of left kidney was more than the right kidney in the renal upper pole located higher than T11.Almost kidney’s inferior poles located at from the L2 inferior edge level to the L3 inferior edge level.In the statistic results,the values measured on CT of left kidney were large or equal to the right except for CL and LC in men,LC in women,total LC and LS.The width in men,total length and width and total upper distance were of significant statistics meaning(P<0.005).The most value measured on CT in men were large than that in women and the LS in men and women,upper and inferior distance were all of significant statistics meaning(P<0.005).Conclusion The data of normal vivo renal location,size and shape obtained in this study can be used as the values consulted by clinic diagnosis,treatment and teaching.更多还原
