A magnetization-prepared, triggered three-dimensional steady-state free precession technique was evaluated for imaging carotid artery disease in patients under investigation after transient ischemic attacks and stroke. The technique was compared to 3DTOF, and continuous 3DSSFP. Correlation was made with doppler ultrasound. The results suggest that triggering the 3D SSFP acquisition to diastole can result in good depiction of slight stenosis (<50%), but often fails in the presence of more significant stenosis.
