Normal Vivo Renal Imaging: Study with Multi-slice Spiral CT / 实用放射学杂志

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
