E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
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 |
Déterminer si la TEP/TDM au 68Ga-DOTATOC est suffisamment sensible pour identifier les myocardites en phase aigüe inflammatoire dans une population de patients hospitalisés pour douleur thoracique et pour lesquels une haute probabilité de myocardite a déjà été identifiée en utilisant l’IRM. La prévalence de la maladie sera proche de 100% à l’inclusion pour ces patients |
|
E.2.2 | Secondary objectives of the trial |
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. |
1. Evaluer la fréquence des formes pouvant être encore inflammatoires (formes possiblement subaigües ou chroniques), avec la TEP/TDM au 68Ga-DOTATOC réalisée 3 à 5 mois après l’inclusion, lorsque les signes classiques d’évolutivité et d’inflammation aigüe ont généralement disparu (CRP, Troponine-I, œdème myocardique en IRM).
2. Analyser la concordance des résultats obtenus par une lecture réalisée en aveugle par deux médecins nucléaires séniors.
