Scanning and angiography in the diagnosis of pulmonary embolism

Lung scanning is a safe and simple procedure which, when correlated with chest roentgenograms and clinical picture, is a valuable tool in diagnosing pulmonary embolism. Pulmonary arteriography is a valuable diagnostic procedure and should be employed when serious doubt exists as to the presence or absence of pulmonary emboli. It should also be used whenever surgical treatment is under consideration.
