Topic: Risk, prevention and care in population studies
PREDICTOM MRI protocol contains eight different datatypes. Figure 1 and Figure 2 contain the main parameters and exemplary images in one healthy volunteer scanned in one of the PREDICTOM clinical centers. The choice of QSM was driven by its performance to better detect microbleeds (3). The MRS acquisition has been included due to consistent evidence of alterations in N-acetylaspartate and myo-Inositol in early stages of AD (4). For scanner with lower gradient performance, the rsfMRI protocol might use slightly partial Fourier and the multi-shell diffusion will be reduced to 2-shell protocol, excluding b=2000. The protocol has been tested on 4 scanners (2 vendors, 3 models) and the harmonisation is still in progress. The PREDICTOM MR protocol was designed to allow the exploration of existing and novel MRI biomarkers for early identification of people at high risk of developing AD.

Key findings
- PREDICTOM MRI protocol contains eight different datatypes.
- Figure 1 and Figure 2 contain the main parameters and exemplary images in one healthy volunteer scanned in one of the PREDICTOM clinical centers.
- The choice of QSM was driven by its performance to better detect microbleeds (3).
- The MRS acquisition has been included due to consistent evidence of alterations in N-acetylaspartate and myo-Inositol in early stages of AD (4).
- For scanner with lower gradient performance, the rsfMRI protocol might use slightly partial Fourier and the multi-shell diffusion will be reduced to 2-shell protocol, excluding b=2000.
Why it matters
This paper describes the design of the PREDICTOM MRI protocol, which includes eight datatypes and was created to explore existing and novel MRI biomarkers for early identification of people at high risk of developing Alzheimer's disease. It is a protocol design for early identification, not a treatment, cure, or prevention study.
