ObjectiveThis study aimed to evaluate the incidence of pulmonary embolism (PE) and tomographic findings in patients who underwent multislice computed tomography (MSCT) for suspected PE in the emergency department.MethodsWe assessed the radiologic and medical records of 212 cases undergoing MSCT for suspected PE in the emergency department for a period of 16 months. A total of 201 cases were included in the final analysis. Age, gender, admission symptoms, risk factors and MSCT findings were recorded. The final diagnosis assigned to each patient was determined.ResultsThe PE incidence was found to be 24.4%. Forty-nine of the cases (24.4%) were diagnosed with PE, while 152 (75.6%) had non-thromboembolic pathologies. There was no statistically significant difference between the patients with and without PE with respect to mean age, symptom status and gender (p > 0.05). Among the risk factors for PE, only the presence of previous surgical operation was statistically significant. Forty-three of the cases with PE (87.7%) and 118 of those without PE (77.6%) had additional parenchymal abnormalities. Linear atelectasis was the only significant difference in MSCT between patients with PE and those without PE (p < 0.001). A thrombus was detected in the main pulmonary artery (PA) in 15 patients (30.6%) and in right main PA in 12 patients (24.4%).ConclusionAlthough PE is not diagnosed in the majority of the cases undergoing MSCT for suspected PE, many miscellaneous information, either relevant to patient's clinical signs and symptoms or incidental, may be obtained.
