摘要:
The invention provides for a magnetic resonance imaging system (100) which comprise a magnet (104) and a magnetic field gradient generator (110, 112) for generating a gradient magnetic field within an imaging zone (108). The gradient magnetic field is aligned with a predetermined direction. The magnetic resonance imaging system further comprise a memory (134, 136) for storing machine executable instructions (150, 152, 154), a pre-calculated magnetic resonance fingerprinting dictionary (144), and pulse sequence instructions (140). The pulse sequence instructions cause the magnetic resonance imaging system to acquire the magnetic resonance data according to a magnetic resonance fingerprinting technique. The magnetic resonance fingerprinting technique encodes the magnetic resonance data as slices (125). The pre-calculated magnetic resonance fingerprinting dictionary contains a listing of calculated magnetic resonance signals in response to execution of the pulse sequence instructions for a set of predetermined substances. Execution of the machine executable instructions causes a processor (130) controlling the magnetic resonance imaging system to: acquire (300) the magnetic resonance data by controlling the magnetic resonance imaging system with pulse sequence instructions divide (302) the magnetic resonance data into a set of slices calculate (304) the abundance of each of the set of predetermined substances within each of the set of slices by comparing the magnetic resonance data for each of the set of slices with the pre-calculated magnetic resonance fingerprinting dictionary and calculate (306) a magnetic resonance fingerprint chart by plotting abundance of each of the set of predetermined substances within each of the set of slices as a function of position along the predetermined direction.
