1. A medical system comprising:
a memory storing machine executable instructions;
a computational system, wherein execution of the machine executable instructions causes the computational system to:
receive k-space data descriptive of a region of interest of a subject, wherein the k-space data is acquired using a magnetic resonance fingerprinting pulse sequence configured for encoding chemical shifts; said magnetic resonance fingerprinting pulse sequence involving acquisition of a pulse train of multiple MRF signal train segments,
receive fat peak weights descriptive of a magnetic resonance fat spectrum, for respective MRF signal train segments so that the fat peak weights are matched to the MRF signal train segments of the pulse train of the magnetic resonance fingerprinting pulse sequence; and
reconstruct a quantitative magnetic resonance image from the k-space data and the fat peak weights.
