Patent ID: 10888246

Abstract:
The present document relates to a method for generating a contrast enhancement map of a portion of a patient. The method comprises acquiring a magnetic resonance, MR, quantification sequence of the portion, wherein the MR quantification sequence comprises quantification information of a longitudinal R1 relaxation rate, R1, and proton density, PD, of the portion, generating an R1 map of the portion based on the MR quantification sequence, wherein a value of R1 for each voxel of the R1 map is determined, generating a PD map of the portion based on the MR quantification sequence, wherein a value of PD for each voxel of the PD map is determined, estimating a R1′ map of the portion, based on the PD map and a predetermined relationship of R1 and PD of the portion, wherein an estimated value of R1 for each voxel of the R1′ map is calculated, generating a delta R1 map based on the R1 map and the R1′ map. The voxels of the R1 map, of the PD map, of the R1′ map, and of the delta R1 map, have a one to one correspondence. A value of each voxel of the delta R1 map represents a difference of R1 values of the corresponding voxel of the R1 map and of the corresponding voxel of the R1′ map.
