作者研究了16例成人呼吸窘迫综合征(ARDS)病人急性期与恢复期的CT资料。男、女各8例,年龄17～65岁,均符合ARDS诊断标准。从突然发病到初次CT扫描。间隔平均为5天(3～21天),初扫与随访的间隔平均为188天(120～1080天)。CT扫描用电子束超CT扫描仪,从肺尖到肺底,间隔10mm,层厚3mm,高空间分辨重建,全部采用肺窗显示。急性期扫描,病人仰卧,用反比压力控制通气<压力限于3.4～3.9kPa(35～40cmH_2O)>,机械通 The authors studied CT data from 16 adult patients with respiratory distress syndrome (ARDS) at acute and convalescent stages. 8 males and 8 females, aged from 17 to 65 years old, all in line with ARDS diagnostic criteria. From sudden onset to initial CT scan. Interval averaged 5 days (3 to 21 days), initial scan and follow-up interval averaged 188 days (120 ~ 1080 days). CT scan with electron beam super CT scanner, from the apex to the bottom of the lung, interval 10mm, thickness 3mm, high spatial resolution reconstruction, all with lung window display. Acute phase scan, the patient supine, with inverse pressure control ventilation , mechanical ventilation
