Abstract
Background: This study aimed to establish the optimal cutoff values for visual amyloid positivity using standardized uptake value ratios (SUVRs) in [18F]flutemetamol (FMM) positron emission tomography (PET) imaging. Given the variability in amyloid assessment, our goal was to determine cutoff values that enhance diagnostic accuracy and assist clinicians in reliably identifying amyloid positivity.
Results: The identified cutoff values for visual amyloid positivity were > 1.6 for the cerebellar gray matter, > 1.38 for the whole cerebellum, and > 0.63 for the pons, yielding high sensitivity (95.5%, 94.5%, and 95.8%, respectively) and specificity (91.2%, 94.3%, and 95.2%, respectively).
Conclusions: The SUVR cutoff values demonstrated excellent diagnostic performance, supporting their clinical use in assessing visual amyloid positivity in [18F]FMM PET imaging.

期刊介绍:
EJNMMI Research publishes new basic, translational and clinical research in the field of nuclear medicine and molecular imaging. Regular features include original research articles, rapid communication of preliminary data on innovative research, interesting case reports, editorials, and letters to the editor. Educational articles on basic sciences, fundamental aspects and controversy related to pre-clinical and clinical research or ethical aspects of research are also welcome. Timely reviews provide updates on current applications, issues in imaging research and translational aspects of nuclear medicine and molecular imaging technologies.
The main emphasis is placed on the development of targeted imaging with radiopharmaceuticals within the broader context of molecular probes to enhance understanding and characterisation of the complex biological processes underlying disease and to develop, test and guide new treatment modalities, including radionuclide therapy.
