Pneumonia: Does Ultrasound Replace Chest X-Ray? Abstract. Pneumonic lung consolidations are characterized by typical changes in terms of sonomorphology: echopoor lesions with blurred margins, bronchoaerograms, regular vascularization, and parapneumonic effusions. Pneumonias may be first discovered at bedside. Reventilation is well correlated with clinical progression. Compared with CT in four metaanalyses, lung ultrasound shows accuracy with a sensitivity of 88-97 % and a specificity of 90-96 %. Chest x-ray on the other hand has a pooled sensitivity of 77 % and a specificity of 91 %. Thus, lung ultrasound should replace chest x-ray in the diagnosis of pneumonia aquired by out-patients.
