摘　　要：目的:利用多排螺旋CT最佳期相自动选择技术(Best phase),获得心脏收缩末期与舒张末期图像,进一步探讨年龄、性别对心脏形态学变化的影响。方法:利用3种方案对118例健康志愿者进行分组。方案一:按年龄分为A组(≥60岁,49例)和B组(<60岁,69例);方案二:按性别分为C组(男,54例)、D组(女,64例);方案三:综合性别与年龄因素分为四组:a组(男,年龄≥60岁,20例),b组(男,年龄<60岁,34例),c组(女,年龄≥60岁,29例),d组(女,年龄<60岁,35例)。利用Best phase技术所获得的心脏收缩末期与舒张末期CT图像,测量对比分析各心腔大小。结果:两期CT图像测量指标组间对比:A组左心房各指标均大于B组(P<0.05);C组左、右心室各指标均大于D组(P<0.05);d组左心室各指标小于其它三组(P<0.05),d组左心房舒张末期各指标也小于其它3组(P<0.05),d组收缩末期各指标小于a组和c组(P<0.05),b组右心室各指标均大于c组和d组(P<0.05)。结论:通过对多排螺旋CT Best phase技术获得心脏图像进行测量分析,随着年龄增大,左房增大明显,男性两心室明显大于女性。Objective:The best phase automatic selection technique (Best phase) of multi-slice spiral CT was used to obtain images of cardiac end-systolic and end-diastolic dysfunction.And the effects of age and gender on cardiac morphological changes were further explored. Methods:118 healthy volunteers were grouped by using three protocols.Option 1:They were divided into group A (≥60 years old,54 cases) and group B (<60 years old,69 cases) by age;Option 2:They were divided into group C (male,54 cases) and group D (female,64 cases) by gender;Option 3:They were divided into four groups by integrating gender and age:group a (male,≥60 years old,20 cases),group b (male,<60 years old,34 cases),group c (female,≥60 years old,29 cases),group d (female,<60 years old,35 cases).The cardiac end-systolic and end-diastolic CT images obtained by Best phase technique were used to measure and compare the size of each heart chamber. Results:The measurement indicators of cardiac end-systolic and end-diastolic CT image were compared among groups:The indicators of left atrium of group A was larger than that of group B ( P <0.05);The indicators of left and right ventricular of group C was larger than that of group D ( P <0.05);The indicators of left ventricle of group d was smaller than that of the other three groups ( P <0.05);The indicators of left atrium end-diastolic of group d was smaller than that of the other three groups ( P <0.05);The indicators of cardiac end-systolic of group d was smaller than that of group a and group c ( P <0.05);The indicators of right ventricle of group b was larger than that of group c and group d ( P <0.05). Conclusion:The cardiac CT images obtained using best phase automatic selection technique of multi-slice spiral CT were measured and analyzed.The left atrium increased significantly with the increasing age and the size of ventricles of male was larger than that of female.
