本文旨在就伴随增龄,老年人较非老年人经多导CT扫描所示的胸主动脉升支和降支内径是否将逐渐递增进行了评估。对象与方法624例受检对象,研究中均接受多导经胸64位CT扫描,以期测评胸主动脉升支及降支内径大小。最后旨在比较分析在不同年龄的老年人与非老年人间,如23~50岁段、51~ This article aims to assess whether the ascending thoracic aortic branches and descending branch anterograde diameters, as shown by multi-CT scans in older adults than in older adults, are assessed as progressive. Subjects and Methods 624 subjects, all receiving multi-guided CT 64-slice CT in order to evaluate the thoracic aortic ascending and descending diameter size. The final purpose is to compare the analysis of different ages of elderly and non-elderly, such as 23 to 50 years of age, 51 ~
