Abstract

Experience gained in the study of 307 patients by pulmonary angiograms and/or isotope lung scans has led to concepts regarding the limitation and usefulness of each. The scan is ideally useful when the patient with suspected pulmonary embolism has a negative chest film. Angiograms should be performed when there are parenchymal infiltrations on the chest radiograph or when a definite diagnosis is necessary. Either study should be performed early in the course of the patient's illness to permit diagnostic study.
