DETECTION OF DEMYELINISING AND ACTIVE LESIONS OF MULTIPLE SCLEROSIS AT 3 TESLAS : 2D versus 3D PROTOCOLS

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.
