Measurement of T2 of an ROI of arbitrary shape using spatially selective excitation

A novel protocol of making quantitative T2 measurement using interleaved spatially selective excitation pulses is proposed. This new technique acquires signals from the entire ROI as a single voxel by encoding in the excitation phase rather than after acquisition, resulting in the SNR proportional to the ROI area. The obtained SNR per unit measuring time is potentially significantly higher than the conventional imaging methods. Phantom experiments are conducted to demonstrate the feasibility.
