Amyloid-related imaging abnormalities(ARIA)are found in relation to amyloid β and the frequency increase after treatment with anti amyloid β antibody. These findings are classified to ARIA-E(edema/effusion)and ARIA-H(hemosiderosis/microhemorrhage). ARIA-E manifest as hyperintese area in the white matter and hypertintense rim in the cortical surface. ARIA-H appears as cerebral microbleeds, cortical superficial siderosis and subcortical hemorrhage. This review overviews the etiology, clinic-radiological characteristics of ARIA, and thereby, reveals tips to diagnose ARIA efficiently.
