Dynamic gadolinium contrast-enhanced (DCE) vessel wall
imaging has been used to quantitatively assess the
inflammatory status of carotid plaques. In this study,
compressed sensing was applied to improve the temporal
resolution of carotid wall DCE MRI from about 20s to
about 8s. With this improvement, SRDIR DCE is promising
for quantitative assessment of the inflammatory status
of carotid plaques, an important biomarker for the
vulnerability of the plaque.
