Description
Quantitative relaxometry and fat fraction mapping at ultrahigh field are important areas of research, hindered by the significant challenges imposed by the high field inhomogeneities. Here, we used a modified MR Fingerprinting scheme based on a spectral-spatial excitation to obtain robust water T1/T2 quantification and fat fraction mapping of the lower extremities of a healthy volunteer within a relatively short acquisition time. Using the proposed approach, we successfully obtained water-fat M0, water-only T1/T2 and fat fraction maps of MSK tissues. In future work, we will use advanced iterative or deep-learning based reconstruction techniques to accelerate the acquisition and compensate for the increase in scan time due to the dual pulse scheme while maintaining a reasonable imaging quality and spatial resolution, together with parallel transmission techniques to further increase image homogeneity.
