Sixty-nine patients with nonpenetrating pulmonary trauma were studied by chest computed tomography (CT) within 24 hours of admission. The percentage of air-space filling was quantitated and compared with the requirement for ventilatory support. Pulmonary intraalveolar hemorrhage always is gravity dependent originating at the site of injury. Utilizing CT, the patients' pulmonary status was classified into three separate clinicoradiologic groups: Grade I injury (less than 18% air-space filling, no ventilator support required), Grade II injury (18-28% air-space filling, ventilator support sometimes required), and Grade III injury (greater than 28 air-space filling, ventilator support always required). The CT quantitation correlated with clinical functional studies and was useful in the therapeutic management of nonpenetrating lung injury.
69例非穿透性肺损伤患者在入院后24小时内接受了胸部计算机断层扫描（CT）检查。对气腔充盈百分比进行了定量分析，并与通气支持需求进行了比较。肺肺泡内出血总是依赖重力，起源于损伤部位。利用CT，将患者的肺部状况分为三个不同的临床放射学组：I级损伤（气腔充盈小于18%，无需呼吸机支持）、II级损伤（气腔充盈18%-28%，有时需要呼吸机支持）和III级损伤（气腔充盈大于28%，总是需要呼吸机支持）。CT定量分析与临床功能研究相关，对非穿透性肺损伤的治疗管理很有帮助。
