Role of Dual Energy Computed Tomography in Detection of Pulmonary Thromboembolism - A Prospective Observational Study in a Tertiary Care Centre of Central India

This study evaluates the diagnostic effectiveness of dual energy computed tomography pulmonary angiography DECTPA in detecting pulmonary embolism PE. PE is a critical cardiovascular condition with significant mortality risk, making early diagnosis essential. DECTPA provides enhanced imaging by using dual Xray energy spectra, allowing for detailed visualization of both emboli and lung perfusion defects. This crosssectional study included 136 patients clinically suspected of PE, and the results demonstrated that DECTPA has high sensitivity 95.12% and specificity 92.31% in diagnosing PE. The right lower lobe and the right pulmonary artery were most commonly affected. Additionally, the study highlights the potential of DECTPA in predicting right ventricular dysfunction, which can guide therapeutic decisions. Overall, the findings support DECTPA as a valuable tool in improving diagnostic accuracy and patient outcomes in pulmonary embolism cases.
