【摘要】 目的 应用影像解剖学技术获取胸廓参数，计算胸廓比，探讨其临床意义。方法 选取浙江台州地区和江苏南京地区560例体检人群、368例原发性自发性气胸（PSP）患者的胸部CT平扫影像，按其年龄及性别进行分组，于T₆平面测量胸廓横径和纵径，并计算胸廓比，进行统计学分析。结果 体检人群正常胸廓比参考范围（1.62±0.14）。单因素方差分析显示，男性（1.60±0.14）和女性（1.67±0.18）组间胸廓比有统计学差异（P<0.01），胸廓比随年龄增大逐渐减小，不同年龄段组间胸廓比有显著差异（P<0.01）。原发性自发性气胸患者人群胸廓参考范围为（1.79±0.20）。其胸廓比与正常胸廓比各年龄组间存在统计学差异（P<0.05）。结论 正常胸廓比参考值的确立可为胸廓畸形的相关疾病提供可靠参照。更多还原

【Abstract】 Objective To measure the anatomical parameters of the thorax by an imaging method,calculate the thoracic ratio, and explore the clinical significance. Methods The computed tomography films of 560 people undergoing medical examinations and 368 patients with primary spontaneous pneumothorax(PSP) were selected in Zhejiang Province and Jiangsu Province. They were grouped according to gender and age. The anteroposterior diameter and the transverse diameter of the thoracic cage were measured at the level of the sixth thoracic vertebra, and the thoracic ratio was calculated for statistical analysis. Results The reference range of normal thoracic ratio was(1.62±0.14). There were significant differences in thoracic ratio between male(1.60±0.14) and female(1.67±0.18)(P<0.01) according to the result of one-Way ANOVA. The thoracic ratio decreased with the increasing of age, and there was prominent difference in thoracic ratio between different age groups(P<0.01). The thoracic ratio of patients with primary spontaneous pneumothorax was(1.79±0.20). There were significant differences in the thoracic ratio between patients with primary spontaneous pneumothorax and normal thoracic ratio among different age groups(P<0.05). Conclusions The establishment of the reference value of normal thoracic ratio can provide a reliable reference for the related diseases of thoracic deformity.更多还原
