Rapid T1 estimation using tagged magnetization-prepared gradient-echo MR imaging



Rapid T1 estimation using tagged magnetization-prepared gradient-echo MR imaging



Magnetic Resonance in Medicine 26(2): 377-385



A technique for estimation of the longitudinal relaxation time of a large homogeneous objective with an acquisition time of 4 s or less was developed by combining spatially selective rf tagging pulses with a T1-weighted magnetization-prepared gradient-echo sequence. Multiple 5-mm-wide tagged areas are laid orthogonal to the imaging section of interest. The contrast between each tag and the untagged region differs because each tag is produced at a different time. The T1 value is determined from the nulling time at which tagged and untagged areas have no contrast.
