The normal pattern of reflection of ultrasound A by the lung is changed by pulmonary thromboembolism with or without infarction. Pulmonary echograms were obtained from 50 normal subjects and 200 patients to determine the reliability of the method in the detection of pulmonary thromboembolism. The echogram from the normal chest is a display fading 2 to 3 cm from the skin-transducer interface. A deeper echo return (4 to 8 cm) is recorded from areas over ischemic lung. A deep pattern was found in 138 patients suspected of having pulmonary thromboembolism. Absolute confirmation of pulmonary thromboembolism was obtained by necropsy or
