要旨:
It is demonstrated that the signal intensity in a RARE (TSE, FSE…)-sequence with low refocusing flip angle α can be significantly increased by setting the flip angle of the first refocusing pulse to 90°+α/2. In addition to the gain in signal intensity, the initial signal modulations over the first few echoes are reduced compared to a CPMG-echo train with constant α.
