PURPOSE: Computed tomography pulmonary angiography (CTPA) is currently the modality of choice for the diagnosis of acute pulmonary embolism (PE). It can also be used to calculate the volumes of the right ventricle (RV) and right atrium (RA) in an automated quantitative method. Risk stratification of PE patients is based on imaging and cardiac biomarkers including troponin. We hypothesized that troponin levels correlate with enlarged right sided cardiac chambers` volumes among patients with acute PE.
