A pectus index can be derived from dividing the transverse diameter of the chest by the anterior-posterior diameter on a simple CT scan. In a preliminary report, all patients who required operative correction for pectus excavatum had a pectus index greater than 3.25 while matched normal controls were all less than 3.25. A simple CT scan may be a useful adjunct in objective evaluation of children and teenagers for surgery of pectus excavatum.
胸廓指数可以通过在简单的CT扫描上用胸部横径除以前后径得出。在一份初步报告中，所有需要接受漏斗胸手术矫正的患者胸廓指数均大于3.25，而匹配的正常对照者均小于3.25。简单的CT扫描可能是客观评估儿童和青少年漏斗胸手术的有用辅助手段。
