As national cohort are trying to establish the best
protocol in order to improve detection of demyelinising
and active lesions in multiple sclerosis, our aim was to
compare two protocols, one only including common 2D
sequences (axial and sagittal FLAIR-wi, axial T2 DUAL
with T2 and proton density wi and axial T1 after
gadolinium injection) and the other only including 3D
sequences (3D FLAIR and 3D T1 FSPGR before and after
gadolinium injection) at 3Teslas. We recommend 3D
protocol which detect significantly more demyelinising
lesions and active lesions with better contrast to noise
ratio and signal to noise ratio.
