There is a bulk of studies exploring spin-echo and multi-echo methods generating T2 weighted imaging and T2 mapping. However, the challenges at 7T MRI include high SAR, long scans and RF inhomogeneity. Steady-state GRE also provide T2 maps based on the magnitude images. A recent study at 3T demonstrated phase-based 3D-GRE with specific RF phase increments producing T2 maps. We propose acquiring four scans from which we can estimate both the T2 and the B1 maps. We denote this method as Steady-state T2 And Rf Estimation (STARE). STARE offers a new capability to acquire fast 3D dataset for T2 mapping.
