“…It must be emphasized that the demonstration of a pulmonary blood perfusion defect by such studies is not in itself proof of pulmonary embolism Swanson et al, 1966;Poe, Swanson & Taplin, 1967). Perfusion defects may result from such conditions as pneumonia, tuberculosis and bronchogenic malignancy; extrapulmonary displacement of lung tissue, for example, by large pleural effusions or cardiomegaly; intrapulmonary bullae; obstructive airways disease-asthma or emphysema; and pulmonary arterio-venous or bronchial artery-pulmonary artery shunting.…”

Summary Pulmonary embolism was first recognized as an important entity early in the nineteenth century. The evolution of our knowledge of this disorder has been reviewed with particular emphasis on the various diagnostic techniques which have been used to assist in its recognition. These have included physical examination to demonstrate the presence of classical physical signs, electrocardiography, biochemical tests, radiological examinations, pulmonary function tests, ultra-sound and methods employing radionuclides. The wide variety of techniques applied to this problem clearly indicates that no currently available test is entirely satisfactory alone. Probably the most significant advance in recent years has been the development of lung perfusion scanning which has provided at the very least a valuable screening test and a ready method of studying serially the natural history of the perfusion defects produced by thromboembolic disease.
