WebThe aim of a FLAIR sequence is to suppress liquid signals by inversion-recovery at an adapted TI. Water has a long T1. Nulling of the water signal is seen at TI of 2000 milliseconds. As in the case of the other inversion-recovery sequences, an imaging sequence of the fast spin echo type is preferable to compensate the long acquisition time ...

WebFast spin echo (FSE) imaging, also known as Turbo spin echo (TSE) imaging, are commercial implementations of the RARE ( R apid A cquisition with R elaxation E nhancement) technique originally described by Hennig et al in 1986. Since that time FSE/TSE has grown to become one of the "workhorse" pulse sequences used in virtually all aspects … WebThe images are primarily T2-weighted. TrueFISP is very sensitive to the inhomogeneities in the magnetic field. The images may contain interference stripes. For this reason, TR should be as short as possible, and a shim has to be performed prior the acquisition. The speed and very low motion sensitivity of acquisition help to make the technique ...
