【 Abstract】 Objective To compare the diagnostic value of lung ultrasound and chest CT for severe pneumo ̄
derwent lung ultrasound examination. Chest CT examination was conducted within 24 h after diagnosing severe pneu ̄
monia. The imaging findings were analyzed. Taking chest CT as golden standardꎬ the diagnostic value of lung ultra ̄
CT 的符合率分别为 80 00% 、60 53% 、87 50% 、83 33% 、76 19% 、66 67% ꎻ以胸部 CT 为金标准ꎬ肺部超声诊
断婴幼儿重症肺炎的灵敏度、特异度、准确度、阳性预测值、阴性预测值、Kappa 值分别为 90 80% 、69 23% 、
