Appropriate Use Criteria (AUC) are statements that contain indications describing when, and how often, an intervention should be performed under the auspices of scientific evidence, clinical judgment, and patient values while avoiding unnecessary provisions of services. SNMMI follows a balanced multidisciplinary approach to guidance development by including various stakeholders in the development process.
While elevated beta amyloid plaques are one of the defining pathologic features of Alzheimer’s, many elderly people with normal cognition also have elevated levels of these plaques, as do people with conditions other than Alzheimer’s dementia. Therefore, the potential clinical use of amyloid PET requires careful consideration so that its proper role may be identified.
To provide guidance for physicians, individuals and families affected by Alzheimer’s, and the public, the Society of Nuclear Medicine and Molecular Imaging (SNMMI) and the Alzheimer’s Association have jointly published the first criteria for the appropriate use of this imaging technology to aid in the diagnosis of people with suspected Alzheimer’s disease.
To develop the new criteria, the Alzheimer’s Association and SNMMI assembled an Amyloid Imaging Taskforce (AIT) consisting of dementia and imaging experts to review the scientific literature and develop consensus recommendations for the clinical use of this promising new technology.
According to the AIT, appropriate candidates for amyloid PET imaging include:
Inappropriate candidates for amyloid PET imaging include:
Amyloid PET imaging is also inappropriate:
“Our primary goal is to provide healthcare practitioners with the information and options available to provide patients with the best possible diagnosis and care in a cost effective manner,” said Maria Carrillo, Ph.D., Alzheimer’s Association vice president of Medical and Scientific Relations.
