[The usefulness of MR angiography (MBA) in the diagnosis of pulmonary thromboembolism].
We report a case of acute pulmonary thromboembolism (PTE) that was accurately diagnosed as PTE by magnetic resonance angiography (MRA). The patient was a 69-year-old woman who exhibited dyspnea. On chest radiography, neither infiltrative shadows nor tumor shadows were observed. Since the lung perfusion scintigram showed segmental defects in both lung fields, MRA was performed. On MRA, blockage of the artery and the perfusion defects in both upper lobes could be seen. We confirmed the diagnosis as PTE on the basis of these typical MRA findings. Our preliminary findings suggest that MRA shows promise as a safe, accurate imaging technique for the diagnosis of PTE.
