Conventional T2 and T1ρ have limited values in evaluating short T2 tissues, and are affected by the magic angle effect. Ultrashort echo time (UTE) sequences can detect short T2 tissues. Magnetization transfer (MT) modeling and adiabatic T1ρ (AdiabT1ρ) seem to be insensitive to the magic angle effect. The combination of 3D UTE-Cones sequence with MT (3D UTE-Cones-MT) and AdiabT1ρ (3D UTE-Cones-AdiabT1ρ) may resolve those limitations. However, patient motion may occur during the relatively long scan time. This study aims to develop 3D UTE-Cones-MT and UTE-Cones-AdiabT1ρ with an elastix registration technique to compensate for motion during the scans.
