Abstract
A method for proton resonance frequency shift (PRF) and T-based temperature mapping using a magnetic resonance imaging (MRI) system includes acquiring, using the MRI system, a set of magnetic resonance (MR) data from a region of interest of a subject by performing a variable-flip-angle multi-echo gradient-echo 3D stack-of-radial pulse sequence. The pulse sequence is configured to acquire radial k-space data in a plurality of segments, each segment acquired with each of a plurality of flip angles. The method further includes generating at least one Tmap based on the set of MR data, generating at least one PRF temperature map based on the set of MR data, generating at least one T-based temperature map based on the set of MR data and displaying the PRF temperature map and the T-based temperature map. In another embodiment, the MR data may be used to generate a plurality of quantitative parameter maps for each of the plurality of MR parameters such as T, proton-density fat fraction (PDFF), and R*.
