【摘要】 目的　了解重症 SATS患者胸部病灶吸收转归的 CT表现。方法　分析 16例重症 SARS患者的 6个月随访 CT表现 ,并对比其出院时 CT表现。结果　全部病例住院期间胸片进展分型 : 型 6例、 型 10例。 6个月随访 CT表现 :单或多发小斑片状磨玻璃影 8例 ( 型 3例、 型 5例 ) ,累计多肺段云絮状影 4例 ( 型 ) ,肺纤维化 3例。与出院时 CT对比 ;全部病例未见新发病灶 ;病灶好转 13例 ( 型 6例、 型 7例 ) ;病灶无变化 3例 (均为 型 ) ;纵隔淋巴结较前减少。结论　 6个月随访 CT显示大部分患者肺部病变继续好转。当前的孤立肺周边部小片磨玻璃影是否是肺纤维化的征像仍是今后随访的主要目的。 SARS患者采用影像进展分型 ,可对患者预后做出预评估。更多还原

【Abstract】 Objective To understand the changes of the CT findings from abnormal to normal as indicated in lung lession of severe SARS patients.Methods Sixteen severe SARS patients were followed up to six months after they were discharged from hospital and the clinical oberservations of CT findings were studied and compared between now and then when they were discharged. Results The development of the diseases of those patients as shown on the CT could be classified into two: 6 cases of Type I and 10 cases of Type II.. The six-month followup indicated that there were 8 cases (3 of Type I and 5 of Type II) who showed ground-glass opacity with little shade alone or more. There were 4 cases (all of Type II) who had cloud-shaped image in multi-lung segments. The rest of 3 cases had fibrosis. Conclusion The six-month followup indicated that most patients showed improvement on their legions of lung. The main aim for a further followup study will be whether the ground-glass opacity has some evidence for fibrosis. The classification of SARS patients based on the progress of the disease on CT may be used for the evaluation purpose in the followups of those patients.更多还原
