This abstract proposes a method for estimating T1, T2, and R2* values from rosette MRF data. R2* and B0 can be extracted from a series of images generated by subdividing the rosette data into partial readouts, and T1 and T2 are determined using the standard MRF pattern matching pipeline. This method was tested on the ISMRM/NIST MRI system phantom to assess the accuracy of the quantitative relaxation measurements.
