💬In plain words
What the trial is, and whether it could suit you
Cardiac damage is the second leading cause of death in patients with sarcoidosis, after lung damage. Today's challenge is to diagnose the disease as effectively as possible, and to develop tools for better risk stratification, especially for sudden death, in order to better target therapies and implantable devices, such as corticoids and immunosuppressant.
The hypothesis is that combined PET (Positron Emission Tomography)/MRI (Magnetic Resonance Imaging) could be a relevant prognostic marker of progression, and would significantly improve diagnostic performance in patients with suspected cardiac sarcoidosis (CS). This study will also make it possible to distinguish sequellar fibrosis lesions from granulomatous lesions and assess the therapeutic response. Incorporating PET/MRI into the diagnostic strategy for patients with suspected CS could therefore improve their management.
