Keywords: MR Fingerprinting, Osteoarthritis, Bilateral Hip Imaging
Motivation: MR Fingerprinting (MRF) can accelerate simultaneous acquisition of multiple quantitative parametric maps with respect to conventional qMRI approaches.
Goal(s): To demonstrate the feasibility of 3D bilateral hip MRF to map T1 , T2 and T1ρ in the hip Joint.
Approach: 3D MRF maps of bilateral hip were acquired for 6 healthy subjects. Parametric maps estimated are compared against parametric maps estimated from VIBE variable flip angle and Turbo-Flash sequences.
Results: Parametric maps obtained from 3D MRF are highly correlated (R-square > 0.89) with parametric maps from reference MRI ; 6.3% - 7.4% variance in 3D MRF parametric maps in repeatability test.
Impact: 3D MR Fingerprinting (MRF) can accelerate the acquisition of parametric maps in the hip joint without considerably effecting the accuracy of the parametric maps.
