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
108 patients
Comparison
ESC-ML vs PET-ML
Outcome
Performance of radiomics and machine learning-based analysis of 18F-FDG PET/CT (PET-ML) as a major criterion for the ESC score (ESC-ML) in PVE diagnosis
