MR imaging has an essential role in the diagnosis of hip disorders such as femoroacetabular impingement (FAI) and osteoarthritis (OA). An increase in pre-contrast T1 is reported in association with cartilage edema and fibrillation and both T2 and T1ρ are shown to be elevated in OA and FAI patients . This work investigates the feasibility of using the MRF sequence introduced in for simultaneous bilateral T1, T2, and T1ρ mapping of the hip joint and assessing the difference between the left and right side cartilage subregions.
