Atherosclerosis is a major cause of ischemic stroke. The high resolution magnetic resonance imaging (MRI) of vessel wall can detect nonstenotic atherosclerotic plaque missed by luminal angiography. To develop a multi-channel radiofrequency (RF) coil system with high spatial resolution and large longitudinal coverage for the intracranial and extracranial arteries vessel wall imaging in one setting. The high resolution images with 0.6 mm³ are obtained with the proposed “24+8” channel coil system from a patient in vivo.
