TSE with DIR is the current technique for identification of the component of
carotid plaque. This approach is limited by inadequate spatial resolution
that is often necessary to identify small areas of plaque components. 3D imaging
offers the potential to improve spatial resolution. We have utilized 3D TSE
with non-selective 180o RF and have implemented an inner volume imaging(IVI)
technique. The non-selective 180o RF allow significantly more echoes to be
acquired resulting in more efficient 3D scan. IVI technique reduces the field
of view in the phase encoding direction and requires fewer phase encoding
line, further reducing scan time.
