CT and MRI are indispensable for routine medical examination of neurovascular disorders. This article describes the imaging findings in acute infarction and carotid plaques, knowledge of which is essential for clinics of equilibrium disorders. Diffusion-weighted images are indispensable for detecting acute infarction, and perfusion MRI also yields important information about the ischemic status. Carotid bifurcation is one of the frequent sites of involvement in atheromatous diseases. A variety of imaging modalities are available for the evaluation of carotid plaques, including conventional contrast angiography, CT, ultrasound, and MRI. MRI is a non-invasive imaging method that reflects the chemical composition, concentration, water content or physical status of the tissues examined.
