Amyloid PET Changes During Lecanemab Treatment in Patients With and Without Amyloid-related Imaging Abnormalities. (PubMed, Clin Nucl Med) - Oct 26, 2026 - "Quantitative analysis using Centiloid showed a greater reduction in amyloid burden in the patient who developed ARIA than in the 2 patients without ARIA. These observations suggest ARIA may be associated with more pronounced treatment-related amyloid clearance, warranting further investigation in larger cohorts."
