18F-FDG-Based Radiomics and Machine Learning: Useful Help for Aortic Prosthetic Valve Infective Endocarditis Diagnosis?
Authors' conclusion
The use of ML for analyzing 18F-FDG-PET/CT images in PVE diagnosis was feasible and beneficial, particularly when ML was included in the ESC 2015 criteria.
Study context
- Population
- Patients with suspected aortic prosthetic valve endocarditis undergoing 18F-FDG positron emission tomography (PET)/computed tomography (CT), single centre, 2015–2021test cohort n = 40
- Participants
