目的 :探讨传染性非典型肺炎的X线表现及变化规律。方法 :对河南省临床诊断的 1 5例患者发病后不同时间的系列胸片和CT进行回顾性分析。结果 :1 5例胸部X线病灶初始形态为斑片状 1 1例 (73.3% ) ,大片状 4例 (2 6 .7% ) ;双侧 9例 (6 0 .0 % ) ,单侧 6例 (4 0 .0 % ) ,均为中、下肺野 (1 0 0 % )。动态观察发现病变进展快 ,病变发展到高峰期时间为 4～ 1 4d , x±s(7.7± 3.2 )d ,双侧 1 3例 (86 .7% ) ,单侧 2例 (1 3.3% ) ,两肺叶及两肺叶以上病变者 1 4例 (93.3% )。病变开始吸收时间为 6～ 2 1d , x±s(1 1 .3± 4 .1 )d ;完全或基本吸收时间 8～ 2 6d , x±s(1 6 .4± 5 .0 )d。1 5例经治疗均痊愈出院。住院时间 1 8～ 4 2d , x±s(31 .9± 7.9)d。 结论 :传染性非典型肺炎的胸部X线特点为急性双侧或单侧多叶炎性浸润阴影 ,以中、下野常见 ,进展迅速 ,及时复查胸部X线对临床诊断及判断病情具有重要价值。
Objective: To investigate the X-ray findings and changes of SARS. Methods: The series of chest radiographs and CT at different time after onset were retrospectively analyzed in 15 clinically diagnosed patients in Henan Province. Results: Fifteen cases of chest X-ray lesion were patchy in 11 cases (73.3%) and large flaps in 4 cases (26.7%). Bilateral 9 cases (60.0%) were unilateral 6 cases (40.0%) were in the middle and lower lung fields (100%). Dynamic observation showed that the lesions progressed rapidly and the lesions reached the peak at 4 ~ 14 days, with x ± s (7.7 ± 3.2) days, 13 cases (86.7%) on both sides and 2 cases (1 3.3%) on one side , 14 cases (93.3%) of the two lobes and more than two lobes lesions. The time of onset of the lesion was 6 ~ 21 days, x ± s (11.3 ± 4. 1) days, and the complete or basic absorption time was 8 ~ 26 days, x ± s (16.4 ± 5.0) days. 1 5 cases were cured after treatment were discharged. The length of hospital stay was 18 ± 42 days, x ± s (31.9 ± 7.9) days. Conclusion: The chest X-ray of SARS is characterized by acute bilateral or unilateral lobular inflammatory infiltration. It is common in middle and lower genital region and has rapid progress. It is of great value in clinical diagnosis and judgment of chest X-ray in time.
