| SPAIR movement artefact |
Dear all,
When scanning wrists in our Avanto MR always the penultimate slice in the transversal series shows a movement artefact. This happens with all patients and always the penultimate slice. We found out that using regular fat saturation this does not occur, with SPAIR (which is preferable because of the frequent susceptibility artefacts in arms/wrists) however it happens all the time. The simple solution for our radiology staff is to use normal fat saturation instead of SPAIR, however we are intriged by this problem and were hoping that anyone also experienced this problem and maybe found an explanation.
Because it happens in only 1 slice we are suspecting some kind of interference of the slice selection pulse with the SPAIR pre-pulses.
Any input is appreciated,
thanks in advance, Matthijs
