Ingenia cx mri

All MRI data were acquired with a 3-Tesla Philips INGENIA CX MRI scanner with a 32-channel dStream head coil. BOLD-fMRI data were collected using single-shot gradient echo type echo planar imaging. The acquisition parameters were as follows: TR = 2000 ms, TE = 30 ms, and flip angle = 90°. During the same session, DTI data were acquired using a single-shot EPI sequence with 32 diffusion directions and b-value of 800. To provide co-registration of functional images, 3D high-resolution T1-weighted images were also acquired. Scan acquisition parameters were as follows: TR = 8.2 ms, TE = 3.7 ms, and flip angle = 8°.

All patients were scanned on the 3T Philips Ingenia CX MRI scanner (Philips Healthcare, Best, the Netherlands) using a commercial 32-channel head coil. The T1-weighted (T1W) images were obtained with a 3D sagittal magnetization-prepared rapid acquisition gradient echo (MPRAGE) sequence (resolution of 1 mm isotropic voxels; field of view = 240 × 240 mm²; 196 slices; flip angle = 8°; inversion time (TI)/repetition time (TR)/echo time (TE) = 494/1339/3.0 ms; data matrix = 240 × 240; bandwidth = 241 Hz/px; SENSE = 2). The structural images of all participants were examined for possible lesions in the cortex, as an exclusion criterion, by two expert radiologists.
