A major challenge to two-component T2* mapping on cartilages in human knee at pixel level is the instability of mapping for the short-T2* component due to insufficient signal-to-noise ratio (SNR) available in clinical setting. A large number of TE acquisitions was proposed in this work to mitigate the demanding of high SNR and stabilize the mapping of short-T2* relaxation. The technical feasibility of this idea was successfully tested in this study.
