New Criteria Developed for Appropriate Use of Cognitive Impairment Imaging Tools

Gil D. Rabinovici, M.D., from the University of California San Francisco, and colleagues updated AUC for amyloid PET and developed AUC for tau PET. Key research questions that guided a systematic literature review on clinical amyloid/tau PET were identified. Based on this review, 17 clinical scenarios were developed in which amyloid or tau PET may be considered. The researchers found that seven scenarios were rated as appropriate, two as uncertain, and eight as rarely appropriate for amyloid PET. Five scenarios were rated as appropriate, six as uncertain, and six as rarely appropriate for tau PET.
