| 目的 分析40例COVID-19患者的影像学表现，探讨胸部CT对该病早期诊断、预后评估的价值。方法 回顾性分析2020年2月1日至3月3日济宁医学院附属医院和济宁市第四人民医院确诊的40例COVID-19患者的临床和影像学资料，总结其影像学特征。结果 病灶单发12例（30%），多发28例（70%）；单侧18例（45%），双侧22例（55%）；单纯磨玻璃密度（GGO）32例（80%），完全实变1例（2.5%），GGO+实性混合密度7例（17.5%）；分布模式为小叶核心型17例（42.5%），胸膜下型7例（17.5%），混合型13例（32.5%），弥漫型3例（7.5%）。伴随征象中血管增粗征17例（42.5%），胸膜平行征10例（25%），空气支气管征8例（20%），晕征7例（17.5%），反晕征1例（2.5%），铺路石征3例（7.5%）。吸收期病变残留纤维条索灶或胸膜下线的有14例（35%）；病变完全消失未残留纤维条索灶的有20例（50%）；以上2种形式均存在的有6例（15%）。有17例第2次CT复查有进展。结论 COVID-19的胸部影像学表现具有一定的特征性，CT在其早期诊断及治疗、转归的效果评价中发挥重要作用。 |

| Objective To analyze and summarize the CT imaging features of Corona Virus Disease 2019 (COVID-19) patients and explore the value of chest CT in early diagnosis and prognosis assessment of the disease.Methods From February 1 to March 3,2020,the clinical and imaging data of COVID-19 patients diagnosed in the Affiliated Hospital of Jining Medical University and The Fourth People's Hospital of Jining were retrospectively collected and analyzed,to summarize their imaging characteristics.Results Single lesion 12 cases(30%),multiple lesions 28 cases(70%);the lesion detected in the lung unilaterally in 18 cases(45%) and bilaterally in 22 cases(55%);32 cases(80%) of ground-glass opacity (GGO),1 case (2.5%) of solid density,7cases (17.5%) of GGO+consolidation.Distribution patterns:centrilobular distribution (17 cases,42.5%),subpleural distribution (7 cases,17.5%),mixed distribution (13 cases,32.5%) and diffused distribution (3 cases,7.5%).Accompanying signs:17 cases (42.5%) with vascular thickening,10 cases (25%) with“pleural parallel sign”;“bronchial inflatable sign” in 8 cases (20%);“halo sign” in 7 cases (17.5%);“reversed-halo sign” in 1 case (2.5%);“paving stone sign”in 3 cases (7.5%).The features of chest CT in clinical outcomes are that lesions in the lung gradually fade and were completely absorbed without residual fibrous cord shadows (20 cases,50%);lesions were absorbed and accompanied by residual fibrous cord shadows (14 cases,35%).There were 6 cases (15%) with the above two forms.17 cases exacerbated in the second CT review.Conclusion COVID-19 patients have certain chest CT characteristics,which plays an important role in the early diagnosis,treatment and outcome evaluation. |
