[HASTE sequence and cine-MRI evaluation of the cervical spinal canal: evaluation in 11 healthy subjects].
OBJECTIVE
We studied 11 healthy subjects were evaluated using cine MR imaging comparing HASTE and gradient echo sequences. Materials and methods :HASTE is a high-speed turbo-spin echo T2-weighted sequence. All examinations were performed using dynamic MRI using a simple process allowing acquisition of images at different stages during flexion and extension. The cine MR evaluation was obtained by rebuilding a cine-loop sequence.


RESULTS
HASTE sequence provides a myelographic effect of the cervical spine. The size, the pattern and the movements of the cervical spine, the spinal cord, as well as the functional reserve of cerebro-spinal fluid are analysable.


CONCLUSIONS
Because of its very high speed, HASTE sequence is particularly useful for cine MR imaging.
