From: Knee dGEMRIC at 7 T: comparison against 1.5 T and evaluation of T1-mapping methods
Comparison of median normalized T1 values at 1.5 T and 7 T in the various ROIs with error bars showing the range of values. The T1 values were normalized to the median T1 value of all healthy subject ROIs at 1.5 T and 7 T, respectively, to enable a comparison between the relaxation times at the two field strengths. Similar normalized T1 values was seen at the two field strengths, and a significantly larger normalized T1 at 7 T compared to 1.5 T was detected only in the deep lateral region in patients (P = 0.04)
