Detection of Amyloid Deposits in the Wrist by MRI With Mapping and High Resolution Sequences in Systemic Amyloidosis (AMYLOCARP)

NCT05150353

CompletedNA

Sponsor: GCS Ramsay Santé pour l'Enseignement et la Recherche

Conditions: Amyloid, Systemic Amyloidosis

Interventions: MRI

Countries: France

This study is based on the hypothesis that MRI could make it possible to non-invasively detect these amyloid deposits at the level of the wrist using parametric sequences known as T1 mapping, in the form of an extension of T1 in the wrists. areas where amyloid deposits are found in the wrist.
