摘要
中国武汉市不明原因肺炎是由一种新型冠状病毒(SARS-CoV-2)感染引起的,传染性强,人群普遍易感。临床症状以发热、干咳、乏力为主,严重者并发急性呼吸窘迫综合征。COVID-19的高分辨CT演变特点:①病灶呈多发性、双侧性分布,以胸膜下及两下肺沿支气管血管束分布多见。②早期以胸膜下斑片状、结节状、团状、节段或亚段性磨玻璃影(GGO)多见,常见血管充血增粗穿行,也可表现为GGO合并实变及纤维化;进展期病灶增多范围扩大,发展为双肺多叶受累的GGO与实变影,小叶间隔增厚及纤维化,也可呈"铺路石征",常见支气管充气征及血管穿行;重症期双肺弥漫性病变,呈"白肺",常见支气管充气征及血管穿行;吸收缓解期可见病灶范围缩小,伴较多纤维化病灶。CT演变特征可为早期诊断与鉴别、病情严重程度评估、及时防控、诊疗决策及治疗评估提供重要依据。
