The purpose of this study was to develop a high-resolution, multi-spectral, quantitative magnetic resonance imaging (qMRI) pulse sequence protocol to interrogate T1, T2, T2*, proton density (PD), diffusion coefficient, and magnetization transfer parameters at ultra-high field (11.7T) MRI. This multi-spectral qMRI pulse sequence was applied to a qMRI phantom containing water, agarose gels, sucrose solutions, and olive oil. Also, the protocol was applied to ex vivo liver imaging of a murine model of steatohepatitis as well as ex vivo murine brain imaging. This comprehensive, multi-spectral qMRI protocol was successfully implemented at 11.7T MRI
