All participants were scanned on the same MRI and PET cameras, a Philips (Best, the Netherlands) Achieva 3.0T scanner and a Discovery RX VCT 64 PET‐CT device (GE Healthcare, Chicago, IL), respectively. A high‐resolution T₁‐weighted anatomical volume was acquired using a 3‐dimensional (3D) fast‐field echo sequence (sagittal, repetition time = 20 milliseconds, echo time = 4.6 milliseconds, flip angle = 10°, 180 slices with no gap, slice thickness = 1mm, field of view = 256 × 256mm², in‐plane resolution = 1 × 1mm²). Resting‐state functional volumes were obtained using an interleaved 2D T2*SENSitivity Encoding (SENSE) echo planar imaging (EPI) sequence designed to reduce geometric distortions using parallel imaging, short echo time, and small voxels (axial, SENSE = 2, repetition time = 2,382 milliseconds, echo time = 30 milliseconds, flip angle = 80°, 42 slices with no gap, slice thickness = 2.8mm, field of view = 224 × 224mm², in plane resolution = 2.8 × 2.8mm², 280 volumes, acquisition time = 11.5 minutes).

All participants were scanned using the same MRI and PET cameras at the Cyceron centre (Caen, France): a Philipps Achieva 3.0T scanner and a discovery RX VCT 64 PET–CT device (General Electric Healthcare), respectively. For each participant, a high-resolution T₁-weighted anatomical image was acquired using a three-dimensional fast field echo sequence (sagittal; repetition time = 20 ms, echo time = 4.6 ms, flip angle = 10°, 180 slices, slice thickness = 1 mm, field of view = 256 × 256 mm², matrix = 256 × 256). Each participant underwent a PET examination the day after the MRI examination. FDG-PET scans were acquired with a resolution of 3.76 × 3.76 × 4.9 mm³ (field of view = 157 mm). Forty-seven planes were obtained with a voxel size of 2.7 × 2.7 × 3.27 mm³. Participants were fasted for at least 6 h before scanning. After a 30 min resting period in a quiet and dark environment, ≈180 MBq of FDG were intravenously injected as a bolus. A transmission scan was performed for attenuation correction and a 10 min PET acquisition scan began 50 min post-injection.

All participants were scanned on the same MRI (Philips Achieva 3.0 T scanner) and PET (Discovery RX VCT 64 PET-CT device, General Electric Healthcare) cameras at the CYCERON Centre (Caen, France). The interval time between the two acquisitions was on average of 17 ± 30 days. Further details on the acquisition procedures are provided in the Supplemental Material.

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.
