18F-FDG PET/CT in the diagnosis of prosthetic valve endocarditis

Prosthetic valve endocarditis is a major diagnostic challenge in clinical practice, due to the lower sensitivity of the modified Duke criteria and a higher percentage of cases with negative or inconclusive echocardiography results. The delay in establishing medical and surgical treatment increases t...
