The cases of pulmonary embolism (PE) are life-taking and potentially lethal challenges for patients without urgent diagnosis and treatment. Imaging is considered a crucial tool in diagnosing PE, encompassing a variety of imaging protocols and techniques. This state-of-the-art review, among other things, looks at the wide range of imaging protocols created specifically for diagnosing pulmonary embolism and discusses their efficiency, benefits, and drawbacks. Moreover, the types of imaging modalities like computed tomography pulmonary angiography (CTPA), ventilation-perfusion (V/Q) scanning, and magnetic resonance imaging (MRI) are investigated, as well as the most advanced novel techniques and recent advances in the field. The review is about the appropriate imaging strategies for different patients, the interpretation issues, and the areas for future research to improve the diagnosis of pulmonary embolism and, consequently, patient outcomes as well.
