A standardised clinical multicentric whole brain T2* mapping protocol at 3T
Résumé
The purpose of this work is to report the implementation of a T2* map in multicenter neuroimaging studies. We focus on T2* because it is an endogenous biomarker for paramagnetic products like iron or melanin, which is very interesting to assess, among other diseases, Parkinson’s disease. We developed a MR sequence which meets several specific requirements. This sequence is accessible on 3 major manufacturer 3T MRI scanners and ensures good measurement accuracy at a standard millimeter isotropic resolution. This “universal” sequence allows to acquire, in a reliable and repeatable way, T2* maps of the whole brain.
