摘　　要：目的通过对正常成人脾脏在多层螺旋CT(MSCT)图像上一些指标的观测分析,提供相应的脾脏正常值范围,为临床和教学服务。方法收集腹部多层螺旋CT扫描正常脾脏160例,并行三维成像,观察脾脏上、下极及脾门中点平椎体的位置。测量脾脏上、下极及脾脏最左、右端、脾门中点距脊柱中线的距离;测量脾脏的长径、厚径及上下径;并对上述结果进行统计学处理。结果脾脏上、下极大部分分别平对T10椎体和L2椎体,脾门大部分平对L1椎体。脾脏的各项CT测量指标男性均>女性,并且除了脾门-中线距、左端-中线距和右端-中线距和厚径之外,其他测量指标差异均有统计学意义(P<0.05)。随着年龄的增长,脾脏的各项CT测量指标均有缩小趋势。结论研究获得了正常成人脾脏的位置、大小、形态的数据,可供临床诊断、治疗以及教学参考。Objective To observe and analyze the standards of the normal adult splenic multislice spiral CT（MSCT） imaging to provide relevant normal range for clinic and teaching.Methods One hundred and sixty cases with normal spleen were undergone abdominal MSCT,then 3D imaging was performed,the position of spleen distance between two poles of spleen,the out edges of right and left of spleen,the midpoint of the splenic hailar and the central line of the spine,the diameter of splenic portal vein and splenic length,thickness and width were observed and measured with statistics analysis.Results Almost splenic upper poles located at the T 10 level,lower poles located at the L2 level and the midpoint of the splenic hailar located at the L 1 level.The values measured on CT of spleen in men were larger than that in women.Except for the distance between the midpoint of the splenic hailar,the out edges of right and left of spleen and the central line of the body and thick of spleen,the most values measured on CT were all of significant statistically（P ＆lt; 0.05）.Along with age increasing,the values measured on CT of spleen in normal adult have a tendency of shrinking.Conclusion The data of normal adult splenic location,size and shape obtained in this study can be used as the values consulted by clinic diagnosis,treatment and teaching.
