Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To determine whether 68Ga-DOTATOC PET / CT is sensitive enough to identify acute inflammatory myocarditis in a population of patients hospitalized for chest pain and for whom a high probability of myocarditis has already been identified using MRI. The prevalence of the disease will be close to 100% at inclusion for these patients;Secondary Objective: 1. Evaluate the frequency of forms that may still be inflammatory (possibly subacute or chronic forms), with PET / CT with 68Ga-DOTATOC performed 3 to 5 months after inclusion, when the classic signs of progressiveness and acute inflammation have generally disappeared (CRP, Troponin-I, myocardial edema on MRI). 2. Analyze the concordance of the results obtained by a blind reading by two senior nuclear doctors.;Primary end point(s): Presence of a significant myocardial uptake which will be (i) visual and (ii) quantitative by measurement of the SUV (Standardized Uptake Values), considered to be significant of 68Ga-DOTATOC during the initial assessment. Calculation of the sensitivity.;Timepoint(s) of evaluation of this end point: upon 36 months | — |
