Computed tomography in massive pulmonary embolism.

The usefulness of computed tomography (CT) for the diagnosis of pulmonary embolism (PE) was demonstrated in two cases. Employing dynamic, contrast-enhanced CT, both direct and indirect signs of PE may be rapidly and conveniently demonstrated. Possible contraindications for therapy may be diagnosed simultaneously and follow-up examinations after therapy may be readily performed. The method serves as a good complement when PE must be verified before treatment with potent agents.
