Presentation transcript:

Reproducibility and Repeatability of MR Fingerprinting Relaxometry in the Human Brain Parameter values in solid brain tissues of healthy individuals measured with FISP MR fingerprinting varied 3.4% for T1 and 8.0% for T2 across 3.0-T scanners. Parameter values in solid brain tissues varied between 2.0% - 3.1% for T1 and between 3.1% - 7.9% for T2. In nonsolid tissues, both repeatability (variation up to 36.2%) and reproducibility (variation up to 18.2%) were substantially worse than in solid tissues. Images show fast imaging with steady-state free precession MR fingerprinting T2 maps in several volunteers. Körzdörfer G et al.
