目的:利用螺旋CT增强扫描测量正常成人心脏及大血管的内腔径线,提供判断心脏大血管病变时大小的参照。方法:随机检查110例无心脏大血管疾患者,男69例,女41例,平均年龄45.5岁;测量心脏横径、左右心房室、间隔、主动脉、肺动静脉、腔静脉及气管和主要分支,再利用SPSS统计学软件进行处理,得出正常值。结果:获得中国人螺旋CT正常心脏大血管各参数;在相近同层面,其间存在多重相关比例。结论:螺旋CT增强扫描对心血管病变的诊断具有重要临床意义。
OBJECTIVE: To determine the size of heart macroangiopathy by spiral CT enhanced scan of the lumen diameter of normal adult and large vessels. Methods: One hundred and fourty patients without heart and macrovascular disease were randomly examined. There were 69 males and 41 females, with an average age of 45.5 years. The cardiac diameter, left atrium, atrial septum, aorta, pulmonary veins, vena cava and trachea were measured. Branch, and then use SPSS statistical software for processing, come to normal. Results: The parameters of normal large blood vessels in Chinese spiral CT were obtained. In the same level, there were multiple correlations. Conclusion: Spiral CT enhanced scan has important clinical significance for the diagnosis of cardiovascular diseases.
