Images were acquired on a 1.5-T Siemens Magnetom Sonata Maestro Class system equipped with a standard headcoil. A structural 3D image was obtained with a standard T1-weighted pulse sequence: 176 transverse slides, TR = 1970 ms, TE = 3.93 ms, flip angle of 15°, FOV = 256 × 256 mm, voxel size: 1.0 × 1.0 × 1.0 mm. In vivo¹H MRS measurements were acquired with PRESS sequence (TR = 1500 ms; TE = 30 ms; Spectral Bandwidth = 1000 Hz; Averages = 16; 1024 samples) with and without suppression of water signal (CHESS sequence). A 2 × 2 × 3 voxel of interest (12 cm³) was positioned on the 3D anatomical MRI to acquire signal in the left and the right DLPFC (Fig. 3).Figure 3

Multimodal Brain Imaging Protocol: DTI and T1-MRI

DTI and T1-weighted MRI images were acquired on a 1.5-T Siemens Magnetom Sonata Maestro Class system equipped with a standard headcoil, at the “CERMEP-Imagerie du vivant” research imaging center of Lyon, France. Head motion was restricted using foam padding. Structural images were obtained with a standard T1-weighted pulse sequence: TR = 1.97 ms, TE = 3.93 ms, flip angle of 15°, FOV = 256 × 256 mm, voxel size: 1.0 × 1.0 × 1.0 mm. Whole brain DTI images were then acquired using a spin-echo EPI sequence (TR = 3800 ms, TE = 96 ms) with 128 × 128 phase-encoding over a FOV of 320 × 320 mm² and 51 axial slices of 2.5 mm thickness. DTI images were acquired in 24 directions with b values of 0 and 1000 s/mm². Six acquisitions were made and averaged at b = 0 and 3 acquisitions in other directions. The scan duration for the DTI sequence was about 10 min.

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.
