摘　　要：目的分析新型冠状病毒肺炎(COVID-19)患者出院后首次胸部CT随访的影像学特点。方法回顾性分析68例COVID-19患者的胸部CT影像学资料。A组45例,为普通型患者,出院后10~33(17.22±4.32) d首次复查胸部CT;B组23例,为重型患者,出院后16~34(18.87±6.86) d首次复查胸部CT。比较两组患者肺内残留病变分布、CT征象变化和双肺半定量视觉评分。结果两组肺内病变均以磨玻璃密度影为主,条索影次之。A组未见肺内明显病灶患者比例高于B组(35.56%vs.4.35%)(P<0.01),而累及2个及以上肺叶患者比例低于B组(44.44%vs.82.61%)(P<0.01)。A组患者左肺、右肺评分以及双肺总评分均低于B组(P<0.01)。结论COVID-19患者出院后肺内病灶吸收快;部分普通型患者肺内病灶完全吸收,仅少数患者遗留纤维性病灶。重型患者CT上残留的主要病变为磨玻璃密度影和条索影,需进一步随访观察。Objective To analyze the imaging characteristics of the first chest CT follow-up of the patients with coronavirus disease 2019(COVID-19) after discharge.Methods CT imaging data of 68 COVID-19 patients were retrospectively analyzed.The first chest CT follow-up after discharge was performed on 10-33(17.22±4.32) days in 45 COVID-19 patients of common type(group A),which was carried out on 16-34(18.87±6.86) days in 23 severe COVID-19 patients(group B).The distribution of residual lesions,changes of CT signs and semi-quantitative visual scores of both lungs were compared between the two groups.Results In the two groups,the main lesion in the lungs was grinded glass density shadow and stripe shadow was the second common sign of the lung lesions.The percentage of patients with no obvious residual lesions on CT imaging was less in group A than that in group B(35.56% vs.4.35%)(P<0.01).So did the percentage of patients with two or more residual lesions(44.44% vs.82.61%)(P<0.01).The scores of left and right lungs and the total score of both lungs were lower in group A than those in group B(P<0.01).Conclusion The absorption of pulmonary lesions in COVID-19 patients after discharge is quicker,which is even complete in some of the common type patients.Only a few patients with severe COVID-19 may leaves fibrous lesions,which needs to follow up further.
