Computer-Aided Detection, Pulmonary Embolism, Computerized Tomography Pulmonary Angiography: Current Status

Abstract: Angiography (mostly computed tomography, but in some cases, conventional) is still the gold diagnostic standard in the clinical diagnosis of pulmonary embolism (PE). Computeraided detection (CAD) is software that alerts radiologists the presence of PE during computerized tomography pulmonary angiography (CTPA) examinations. Interpreting CTPA scans with the aid of commercially available CTPA-CAD has improved the detectability of PE patients. This chapter aims to complete the scope of this book by explaining the… Show more

“…The emergence of deep learning (DL), a subfield of artificial intelligence (AI), has increased interest in automatized detection and diagnostic tools in radiology [ 13 ]. Before that, multiple different computer-aided detection (CAD) models for diagnosing PE had been developed using manually encoded methods like segmentation, detection of low-attenuated areas, and/or feature analysis [ 14 , 15 ]. Use of CAD as a concurrent reader has been shown to increase reader sensitivity [ 16 ], but high yield of false positives (FPs) has remained as a major drawback [ 17 ].…”
