- Abstract
Background: We compared the effectiveness of multi-detector row computed tomography (MDCT) angiogram and Ventilation-Perfusion scintigraphy (V-P scintigraphy) in the diagnosis of acute pulmonary embolism (PE). Methods: Thirty-nine patients (17 men, 22 women, mean age of 542), in whom acute PE was suspected, underwent MDCT (collimation, 4 x 1,3 mm; pitch, 1.25; scanning time, 0.5 second, 120 kV, 150 mAs) and Ventilation-Perfusion scintigraphy within 48 hours after the hospital admission. Patients in whom pulmonary embolism was not found at both MDCT and V-P scintigraphy were clinically followed up at least 3 months. The final diagnosis was reached according to clinical, radiological and scintigraphy findings. MDCT and V-P scintigraphy findings were compared with each other in terms of presence and location of pulmonary embolism. Results: Final diagnosis for the 39 patients were pulmonary embolism in 20 (51,3%) and no pulmonary embolism in 19 (48,7%). The sensitivity of MDCT and V-P scintigraphy in the detection of PE was 95% (19 of 20); and 65% (13 of 20). The specificity of MDCT and V-P scintigraphy was 100% (19 of 1 9)and 58% (11 of 19). Conclusions: MDCT is more accurate than V-P scintigraphy in the diagnosis of acute PE. Additionally, MDCT provides the differential diagnoses for patients without PE. MDCI should be considered the first imaging modality in the assessment of PE.
