Direct and indirect finding of pulmonary embolism are important for making the correct diagnosis on pulmonary MRA. We have assessed the prevalence of both expected direct and indirect findings of PE and also evaluated the inter and intra reader agreement of these indirect and direct findings. Our results demonstrate that experienced and inexperienced observers can reproducibly observe direct and indirect findings of PE on CEMRA exams.
