Abstract

Here we describe a super-resolution 3D T2 relaxometry approach using an unbalanced SSFP acquisition with very low flip angle RF pulses (a ≤ 1°). We then apply this to obtain 1mm isotropic T2 maps in a reference phantom, and compare this to both the reference values and a 2D multi-echo spin echo approach. The proposed approach provides new options for high-resolution, low-SAR T2 relaxometry experiments in a range of tissues.
