简介
Background
Harmonized protocols to collect imaging data must be devised, employed, and maintained in multicentric studies to reduce interscanner variability in subsequent analyses.
Purpose
To present a standardized protocol for multicentric research on dementia linked to neurodegeneration in aging, harmonized on all three major vendor platforms. The protocol includes a common procedure for qualification, quality control, and quality assurance and feasibility in large‐scale studies.
Study Type
Prospective.
Subjects
The study involved a geometric phantom, a single individual volunteer, and 143 cognitively healthy, mild cognitively impaired, and Alzheimer's disease participants in a large‐scale, multicentric study.
Field Strength/Sequences
MRI was perform with 3T scanners (GE, Philips, Siemens) and included 3D T1w, PD/T2w, , T2w‐FLAIR, diffusion, and BOLD resting state acquisitions.
