The MR examinations were performed in the routine clinical workup using a 16-channel
dedicated head matrix coil on a 3.0-Tesla MRI system (Siemens Healthcare, Erlangen,
Germany). The sequences of cMRI protocols were gradient-echo T1-weighted imaging (T1WI,
slice thickness of 5 mm), turbo spin-echo T2-weighted imaging (slice thickness of 5 mm),
fluid-attenuated inversion recovery (FLAIR, slice thickness of 5 mm) imaging, and
gradient-echo contrast-enhanced T1WI (CE-T1WI, slice thickness of 1 mm). Spectroscopic
data were obtained as described previously.9 (link) Data were achieved using the multivoxel point resolved spectroscopy, TE/TR:
135/1500 ms, 15-mm section thickness, field of view 120 × 120 mm, and nominal voxel size
of 10 × 10 × 10 mm. Total examination time, including setup, was approximately 30
minutes.
