Abstract
ABSTRACT
Purpose: using hemodynamic indices derived from cardiac MRI and ECG gated multidetector CT angiography during the diagnosis of pulmonary embolism to predict its severity.
Patients & methods: This study was performed on 20 patients that were diagnosed to have pulmonary embolism. All our patients underwent CT scan, among which 10 patients underwent MRI scan, different measurements obtained from CT&MRI including, Pulmonary artery diameter, Right ventricle diameter, left ventricle diameter, IVC diameter as well as septal deviation. Patients were followed to detect the need for ICU admission and incidence of mortality within 30 days short term follow-up.
Results: Right ventricle to left ventricle ratio, Pulmonary artery diameter and septal deviation detected by CT scan and MRI scan were found to be significantly correlated to ICU admission, 30 day mortality.
Conclusion: ECG gated CT scanning of pulmonary embolism not only is a valuable tool for diagnosis but also can be used to assess the severity and outcome of pulmonary embolism. MRI is a promising tool to exclude pulmonary embolism affecting main and lobar branches, it is of greater value to assess the severity, cardiac effect and therefore the clinical outcome.
