Magnetization transfer (MT) imaging is gaining increased attention in the field of cancer imaging. MT imaging of healthy controls was performed at 3T to explore the variability of the magnetization transfer ratio (MTR) of normal fibroglandular (FG) tissue. We were able to produce reliable MTR maps with good fat suppression, and mean MTR values for FG tissue ranged from 20% to 26%.
