The purpose of this work was to develop a 3D ME IR SOS technique to reduce off resonance blurring and allow measurement of T2* in Atherosclerotic plaque. In a prior study we observed lower ADC values in symptomatic IPH. We hypothesized that the T2* measurements from 3D ME IR SOS would help identify IPH and further characterize symptomatic and asymptomatic IPH. The 3D ME IR SOS can provide motion insensitive IPH visualization and T2* values simultaneously which may provide important clinical information to detect the plaque progression.
