Magnetic resonance angiography (MRA) is increasingly used as a non-invasive method to assess carotid arteries. TOF-MRA, because it is dependent on the flow of magnetized blood into the volume being imaged, is highly susceptible to conditions that disrupt laminar flow. Depiction of the carotid region using Silent imaging was often superior to that obtained with conventional techniques, where the ultrashort TE minimized flow-related signal dropout. This study aimed to evaluate the feasibility of PETRA-MRA in imaging the vascular structures of the extracranial carotid arteries. We found that PETRA-MRA showed significantly higher image quality and better visualized extracranial carotid arteries.
