The Centiloid Scale in Amyloid PET Imaging: Current Role in Alzheimer's Disease Diagnosis, Treatment Planning, and Monitoring During Anti-Amyloid Therapy: A Clinical Perspective.

The Centiloid (centiloid) scale, a tracer/scanner-independent, standardized quantification unit introduced in 2015, transforms tracer- and scanner-specific standardized uptake value ratios (standardized uptake value ratios) into a common metric anchored at 0 centiloid in young cognitively unimpaired individuals and 100 centiloid in patients with mild-to-moderate AD.

As with all imaging modalities, the centiloid has physiologic and technical limitations.
