Meniscus plays a critical role to maintain mechanical function of knee and is related to initiation of osteoarthritis. Although several papers have demonstrated the feasibility of using UTE sequence to target the short T2 component and derive the corresponding T2* map, it is not easy to assess the in vivo human meniscus T2* value with high resolution due to a relatively long scan time. The purpose of this study is using dual echo radial imaging sequence conjugated with undersampled projection reconstruction for accelerated meniscus T2* measurements. The present finding indicated that the use of the proposed method is able to obtain a reliable T2* value of the in vivo human meniscus.
