DWI has the potential to provide complementary information that will allow better discrimination of plaque components such as lipid core. Iron has consistently been found in higher concentrations in atherosclerotic plaque compared to vessel tissue. In previous studies, intraplaque T2* distinguished symptomatic from asymptomatic plaques in patients with carotid atherosclerosis. In this work we introduce simultaneous measurement of ADC and T2* using a motion insensitive high resolution 3D multiple echo diffusion weighted driven equilibrium Stack of Stars sequence. This technique can provide high resolution T2* and ADC values simultaneously, which may provide important clinical information to detect plaque progression.
