Snapshot imaging using a FLARE sequence.
We have implemented a snapshot FLARE sequence using a scan time of 320 ms for a 64 x 128 image. As in the conventional FLARE sequence the T2 weighting of the image can be altered by manipulating the phase encoding scheme with the position of the zeroth phase encoding effectively determining the amount of T2 weighting. Reducing the flip angle of the refocusing pulse reduces both the RF power deposition and the blurring in images of short T2 samples, at the expense of reduced signal and contrast.
