Abstract
Methods and systems perform magnetic resonance fingerprinting (MRF) by obtaining magnetic resonance data over a main field-of-view (FOV) and resulting from providing a magnetic resonance fingerprinting pulse sequence to a sample. The pulse sequence includes gradient waveforms and radio frequency (RF) pulses that have pulse sequence parameters specifically tailored for scanning, not the entire main FOV but rather a reduced portion of that main FOV. The methods and systems further include comparing the magnetic resonance data from the sample to a fingerprint dictionary of signal profiles that specifically correspond to the reduced portion of the main FOV and generating tissue property maps that correspond only to that reduced portion.
