| 目的 探讨胸部多排螺旋CT（MDSCT）在早期诊断新型冠状病毒肺炎（COVID-19）及病情随访中的应用价值。方法 对40例COVID-19确诊患者（普通型）的初次胸部MDSCT图像及其中15例随访患者的20次复查MDSCT图像进行回顾性分析。结果 初次MDSCT图像COVID-19病变分布以双侧（36/40，90.00%）、胸膜下外带（38/40，95.00%）显著，累及5个肺叶者占70.00%（28/40），90.00%（36/40）病变形态为斑片状、片状及不规则形。40例患者中早期16例，进展期24例，未见消散期病例。早期MDSCT表现为两肺多发磨玻璃密度病灶（GGO），18.75%（3/16）伴淡薄实变，31.25%（5/16）伴明显实变；进展期患者均见不同程度实变。随访15例，4例病变吸收，密度变淡，面积缩小，由进展期转为消散期；11例较前进展。结论 MDSCT可评估COVID-19患者肺内病情变化，对于早期诊断COVID-19及随访具有一定价值。 |

| Objective To explore the application value of chest multi-detector spiral CT (MDSCT) in diagnosis and follow-up of corona virus disease 2019 (COVID-19). Methods The first time chest MDSCT images of 40 common type COVID-19 patients and 20 times re-examinations of MDSCT during follow-up of 15 patients were analyzed retrospectively. Results The first time MDSCT showed that the distribution of lesions were mainly bilateral (36/40, 90.00%) and subpleural extramedullary (38/40, 95.00%), involved 5 lobes in 28 cases (28/40, 70.00%), which were patchy, flaky and irregular shaped in 36 cases (36/40, 90.00%). Among 40 patients, 16 cases were in the early stage, 24 cases of the progressive stage, no case in the dissipation stage. Early stage MDSCT showed multiple ground glass opacity (GGO) in both lungs, 18.75% (3/16) cases with thin consolidation, 31.25% (5/16) cases with obvious consolidation. All progressive stage cases were found with varying degrees of consolidation. Fifteen patients underwent MDSCT follow-up, the absorption of lesions changed from the progressive stage to the dissipated stage in 4 cases, while lesions progressed in 11 cases. Conclusion MDSCT can be used to evaluate the changes of lung condition, which is valuable for early diagnosis and follow-up of COVID-19. |
