We compare two commonly-used T1-weighted volumetric pulse sequences (MP-RAGE and IR-SPGR) at 3T on a series of ten healthy volunteers. The acquisition protocols are adjusted so that the scan times are both 7:23. SNR measurements in both grey and white matter are reported, as is the grey-white contrast to noise ratio. Results of a blinded review by radiologists on qualitative features including image sharpness and artifact level is also provided. Both pulse sequence techniques performed well, but a systematic preference for MP-RAGE was observed.
