Outcome Measures
Primary Outcomes (1)
Determination of diagnostic value of parametric positron emission computed tomography
area under the curve of the Ki parameter (and the Vd parameter) as a function of the presence of endocarditis diagnosed during the multidisciplinary consultation meeting at 3 months
3 months
Secondary Outcomes (1)
Correlation between parametric positron emission computed tomography and scintigraphy with labelled leukocytes
3 months
Study Arms (1)
Parametric positron emission computed tomography
EXPERIMENTALInterventions
Patients will undergo parametric positron emission computed tomography in 15 days after the labeled polynuclear scintigraphy
