Hemorrhage is an important plaque component. It has been reported that Type I (fresh) hemorrhage occurred more often in patients with symptomatic plaques. It has been reported that T2* measurement distinguished symptom-producing from non-symptom producing plaques in patients. A previous ex vivo DWI study reported that the ADC in hemorrhage varies according to the processes that occur during the successive phases of aging. The purpose of this study was to determine retrospectively if T2* and ADC value obtained from a 2D ss-SGE-DWEPI sequence can simultaneously depict differences between symptomatic and asymptomatic carotid atherosclerotic plaque.
