Pulmonary embolism (PE) is potentially life threatening condition which requires adequate diagnosis.\nSince computerized tomography pulmonary angiography (CTPA) described the presence of\na clot subjectively, an objective and quantification method to characterize plural parenchymal\nabnormality, pulmonary vessels and heart is needed (in order to diagnose PE). This study was directed\nto investigate whether the presence of plural parenchymal findings correlates with the PE\nand as well, it was designed to answer two basic questions based on CTPA findings done for clinical\nsuspicion of PE: firstly, what are the plural parenchymal abnormalities associated with PE; secondly,\ncorrelation of PE with the presence of heart changes and pulmonary vessels measurements.\nCTPA scans were acquired for 55 patients suspected of having PE and another 50 subjects who\nwere considered as control. The clinical signs and pleuroparenchymal abnormalities, pulmonary\nartery tree measurements, right ventricle and atrium diameters, Inter ventricular septum width\nas well as the myocardium thickening were characterized and correlated with PE. The results\nshowed that the PE patients group has more dilated measurements than the normal control subjects.\nThe right ventricle diameter changes were found to be significantly related to the presence\nof PE at p 0.001. Significant changes at p 0.005 were also noticed in the pulmonary trunk diameter\nas well as the right and left main pulmonary arteries with no significant changes detected\nin the distal portion of both pulmonary arteries diameters. The common complaints from PE patients\nwere chest pain, shortness of breathing, lower limb swelling, tachycardia and syncope. Consolidation,\nground glass opacifications, mosaic, right ventricle morphological changes and pleural\neffusion were present in the majority of patients undergoing CTPA for the clinical suspicion of PE.\nCTPA is considered as the diagnostic modality of choice in characterization of pulmonary vessels,\natrium and ventricle changes as well as pleura parenchymal abnormalities in patients with or without\nPE
