MRA and CTA exams performed for diagnosis of pulmonary embolism were correlated in 20 prospectively enrolled patients. MRA featured good sensitivity but limited specificity and only moderate inter reader agreement. MRA can serve as a substitute diagnostic tool in patients suffering from pulmonary embolism if CTA is contraindicated or as follow up exams in patients already undergoing thromboembolic therapy.
