DWI might provide a tool for discriminating intraplaque hemorrhage and lipid core from other components. Motion insensitive 3D DW-DE SOS has been developed to acquire high resolution DWI to improve the accuracy of ADC measurements. This technique was able to yield high resolution ADC that could provide clear ROI selection for important plaque components. Increased spatial resolution in motion insensitive 3D DW-DE SOS can improve the sensitivity of ADC maps in plaque component identification. The results obtained indicate that an ADC map may be of substantial value in identifying lipid and hemorrhage within overall plaque burden.
