Aim: Pulmonary embolism (PE) is a disease with a high mortality rate that occurs as a result of the migration of thrombus in the deep veins of the lower extremities into the pulmonary circulation. Contrast-enhanced CT and V/P scintigraphy are two commonly used methods for imaging. This study aims to determine the frequency of parenchymal and non-parenchymal findings on non-contrast CT in patients who are clinically suspected to have PE but who cannot undergo contrast-enhanced CT-angiography and who are diagnosed with PE by lung perfusion scintigraphy. Material and Methods: Thirty-nine patients who were admitted to Tokat State Hospital between 2015 and 2022 with a preliminary diagnosis of pulmonary embolism and who underwent lung perfusion scintigraphy and non-contrast CT scans in the same week were evaluated retrospectively. Results: When computed tomography findings were evaluated in patients with pulmonary embolism, wedge-shaped opacity was present in 3 patients (20%) but not present in 12 patients (80%); consolidation was present in 6 patients (40%) and absent in 9 patients (60%); dilatation in the main pulmonary artery was present in 7 patients (46.7%) and absent in 8 patients (53.3%).Ground-glass opacity was present in 11 patients (73.3%), absent in 4 patients (26.7%); pleural effusion was present in 4 patients (26.7%) but not in 11 patients (73.3%); atelectasis was present in 4 patients (26.7%) but not in 11 patients (73.3%). Discussion: In our study, there was no statistically significant difference between the presence of pulmonary embolism in lung perfusion scintigraphy and the detection of wedge-shaped opacity, consolidation, dilatation in the main pulmonary artery, ground glass attenuation, pleural effusion and atelectasis in thorax CT.
