To overcome this effect in brain T-1-weighted images the, MPRAGE sequence was modified to generate two different images at different inversion times MP2RAGE By combining the two images in a novel fashion, it was possible to create T-1-weigthed images where the result image was free of proton density contrast, T-2* contrast, reception bias field, and, to first order transmit field inhomogeneity.Human BrainIn-VivoMagnetic-ResonanceIntensity-CorrectionAccurate MeasurementRelaxation-TimesPhased-Array3.0 TeslaT-1MriCIBM-AITMP2RAGE, a self bias-field corrected sequence for improved segmentation and T-1-mapping at high fieldtext::journal::journal article::research article
