【摘要】 目的研究严重急性呼吸综合征(SARS)康复患者肺部残留病灶的CT表现及其转归。方法83例临床治愈患者出院1个月后进行X线胸片和CT检查,对肺部有病灶的病例间隔2个月后再次复查X线胸片和CT,对两次随访检查结果进行对比并分析肺部残留病灶与SARS类型的关系。结果30.1%(25/83)病例肺部存在残留病灶,CT表现包括磨玻璃影6例,网状影5例,片状影3例,索条影2例,磨玻璃影和上述其他病灶混合影9例,2个月后复查除两例外均有不同程度吸收;SARS重型病例肺部残留病灶比例(36.8%)高于普通型(15.4%),两者差异有统计学意义。结论部分临床治愈SARS患者肺部存在残留病灶,CT表现以磨玻璃影、网状影为主,SARS重型病例肺部残留病灶比例高于普通型,这些病灶经治疗大部分有不同程度吸收。更多还原

【Abstract】 Objective To study the CT appearance of recovery patients with severe acute respiratory syndrome(SARS) and the changes of lung lesions at follow-up. Methods X-ray examination and CT were performed in 83 patients with SARS one month after discharge.The patients with lung lesions went through X-ray examination and CT after two months again. The X-ray films and CT were analyzed. Results The lesions were found in lungs of 30.1%(25/83)patients.Ground-glass opacity were found in 60% (15/25) patients, the other findings included reticular (5/25),patchy(3/25),streaky(2/25)lesions. there were higher rate of lesions in patients with heavy SARS(36.8%) than common patients(15.4%),the difference was statistically significant. The lesions were absorbed completely( 5 cases) or partly ( 17 cases) at second follow-up,no change in 2 patients.Conclusions Ground-glass opacity and reticular lesion were the chief CT appearance of recovery patients with SARS. There were higher rate of lesions in patients with heavy SARS than common patients.The most lesions of lungs were absorbable partly or completely.更多还原
