The Angiographic Differential Diagnosis of Acute Pulmonary Embolism

Abstract

Angiographic features of nine pulmonary conditions which may simulate acute pulmonary embolism are presented and the differential angiographic features emphasized. A firm angiographic diagnosis of acute pulmonary embolism must be based solely on the demonstration of intraluminal defects or arterial occlusions. Segmental injections are often crucial for a confident differential diagnosis of embolism.
