Structural Magnetic Resonance Imaging (MRI)

Structural magnetic resonance imaging (MRI) is a non-invasive technique for examining the anatomy and pathology of the brain (as opposed to using functional magnetic resonance imaging [fMRI] to examine brain activity).

In L-CID, a high-resolution three-dimensional (3D) T1 MRI scan was performed as an anatomical reference. The imaging parameters used remained constant throughout the waves. The field of view (FOV) for the scan was 224 mm in the anterior-posterior (ap) direction, 177 mm in the right-left (rl) direction, and 168 mm in the foot-head (fh) direction. The imaging parameters used were as follows: repetition time (TR) of 9.72 ms, echo time (TE) of 4.95 ms, and flip angle (FA) of 8°. A total of 140 slices were acquired with a voxel size of 0.875 mm x 0.875 mm x 0.875 mm. The MRI scans were conducted using a Philips Ingenia 3.0 T MRI system, employing a standard whole-head coil. To minimize head motion during the scan, foam inserts were utilized to securely hold the children's heads in place. To ensure a comfortable experience for the participants, they were allowed to watch a child-friendly movie of their choice while undergoing the structural anatomical scan (3DT1).
