Enhancement can be particularly instructive. This study investigated the impact of the duration between contrast administration and image acquisition. The cohort with the longest duration had the greatest increase in signal intensity change. When using vessel wall MR imaging to assess intracranial atherosclerotic disease, protocols should be designed to maximize the duration between contrast administration and image acquisition to best demonstrate enhancement.DANTEdelay alternating with nutation for tailored excitationvwMRIvessel wall MR imagingICADintracranial atherosclerotic diseaseSPACEsampling perfection with application-optimized contrasts by using different flip angle evolutions ER -
