All participants underwent Magnetic Resonance Imaging on a 3-T X-series Philips Achieva clinical MRI scanner (Amsterdam, the Netherlands) using an 8-channel head coil. Both the NCs and the TLE patients underwent identical scanning sessions. In detail, each patient underwent a pre-surgical (mean = 114 days prior to surgery, N = 61) and post-surgical scan (m = 305 days after surgery, minimum of 6 months, N = 48). High resolution T1-weighted images were collected using an MPRage sequence (180 slices, 256 × 256 isotropic voxels; TR = 640 ms, TE = 3.2 ms, FOV = 256 mm, flip angle = 8°, voxel size = 1 × 1×1 mm). Subjects lay in a foam pad to comfortably stabilize the head, and were instructed to remain still throughout the scan.
3 t x series
Manufactured by Philips
The 3-T X-series is a magnetic resonance imaging (MRI) system designed by Philips. It operates at a field strength of 3 Tesla, providing high-resolution imaging capabilities for clinical and research applications. The core function of this product is to generate detailed images of the body's internal structures, enabling healthcare professionals to diagnose and monitor various medical conditions.

All participants underwent Magnetic Resonance Imaging on a 3-T X-series Philips Achieva clinical MRI scanner (Amsterdam, the Netherlands) using an 8-channel head coil. A total of 5 minutes of a resting-state condition was collected. Anatomical and functional acquisitions were similar for all participants. Regarding the resting-state condition, the participants were instructed to remain still, keep their eyes closed but not fall asleep throughout the scan. Single shot echoplanar gradient echo imaging sequence acquiring T2* signal was used with the following parameters: 120 volumes, 34 axial slices acquired parallel to the AC-PC line, TR = 2.5 s, TE = 35 ms, FOV = 256 mm, 128×128 data matrix isotropic voxels, flip angle = 90°. The in-plane resolution was 2*2mm2 and the slice thickness was 4mm. Prior to collection of the functional images, high resolution T1-weighted images were collected using an MPRage sequence (180 slices, 256×256 isotropic voxels; TR = 640ms, TE = 3.2ms, FOV = 256mm, flip angle = 8°, voxel size = 1x1x1mm). Each EPI imaging series started with three discarded scans to allow for T1 signal stabilization.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
