Zusammenfassung

We present a multi-center, multi-vendor study evaluating repeatability and reproducibility of quantitative MRI data acquired using high resolution (1 mm³) multi-parameter mapping (MPM) which provides quantitative R1, MT and R2* maps of the whole brain within less than 18 min. The protocol was implemented at four clinical sites with different Siemens and Philips 3T MRI scanners. Scan-rescan measurement of the same five healthy volunteers at all sites showed good intra-site reproducibility in all parameter maps. However, tThe inter-site comparisons showed a higher reproducibility on Siemens scanner. than on the Philips scanner.
