Imaging and assessment of arterial vessel wall is
challenging due to its small dimension and appropriate
imaging technique has not been well established for this
application. Recently, 3D turbo spin echo sequence
(SPACE) has been used to provide high-resolution image
quality within a feasible scan time. However, a long
echo train which is typically used to shorten scan time
may lead to image artifacts. In this paper, we report
the effect of the wall edge enhancement and broadening
by signal acquired during echo train. The basilar
arterial wall was imaged and studied in comparison with
analytical simulation results.
