Magnetization prepared 3D spiral UTE sequences were developed for T1, T2, T1rho and MTR measurements of fibrous structures. The robustness of the parameter mapping for tendons, ligaments, menisci, cartilage and muscle of the human knee joint was evaluated in a test-retest repeatabilty study. Multiparametric UTE imaging was successfully performed for both test and retest examination. The results of the study demonstrate good repeatability of the applied multiparametric protocol. Parameter maps such as T2 and T1rho show less robustness than T1 and MTR measurements. Especially with small structures as tendons and ligaments, there is the least agreement between scan and rescan.
