Abstract

Intracranial atherosclerosis is a significant cause of ischemic stroke, characterized by the development of atherosclerotic plaques within the walls of intracranial arteries. These plaques can progress to intracranial stenosis, narrowing the arterial lumen and reducing blood flow to critical brain regions. High-resolution magnetic resonance imaging (MRI) and intravascular ultrasound are essential diagnostic tools for detecting and evaluating intracranial atherosclerotic plaques. Early detection and management of intracranial atherosclerosis are crucial for preventing stroke and minimizing long-term neurological damage. It is highlights the pathophysiology, clinical implications, and diagnostic modalities associated with intracranial atherosclerosis.
