Contrast-enhanced 3D T1-weighted Gradient-echo Versus Spin-echo 3 Tesla MR Sequences in the Detection of Active Multiple Sclerosis Lesions

"Due to the participation in the study, the following sequences are added to the imaging protocol:~* 3D T1 GRE after injection (Gradient-Recalled Echo)~* 3D T1 TSE before injection (Turbo Spin Echo)~* 3D fGATIR PSIR after injection (fast Gray Matter Acquisition T1 Inversion Recovery Phase-Sensitive Inversion Recovery)~Sequences will be performed in a random order to avoid the bias induced by different time intervals between injection and acquisition."
