21 emergency room patients with dyspnea were studied with contrast enhanced 2D ARC 3D MRA of the pulmonary arteries. Three patients had a total of 5 emboli identified by this single breath hold MRA technique. In all cases the exam was diagnostic to the segmental level. This method can be safely used for young patients in whom radiation dose from CTA is problematic.
