T1 mapping in the cartilage offers a valuable diagnostic tool in degenerative disease of the cartilage. Three dimensional Inversion Recovery Fast Spoiled Gradient Echo (IR-FSPGR) is widely accepted protocol for T1 mapping of the cartilage. In our study we investigated the feasibility and quality of an alternative acquisition technique that is based on 2D Inversion Recovery Fast Spin Echo (IR-FSE).The proposed sequence is a modified version of IR-FSE, where inversion and acquisition is consecutively performed on different slices without Inversion Time (TI) delay.
