Practice parameters and technical standards are published annually with an effective date of October 1 in the year in which amended, revised, or approved by the ACR Council. For practice parameters and technical standards published before 1999, the effective date was January 1 following the year in which the practice parameter or technical standard was amended, revised, or approved by the ACR Council. Development chronology for this practice parameter: 2015 (Resolution 21). Clinical Nuclear Medicine: February 2016 - Volume 41 - Issue 2 - p 118-125 doi: 10.1097/RLU.0000000000001037 Buy Metrics Abstract This practice parameter is for both FDG and amyloid brain PET or PET/computed tomography (CT) for patients with cognitive decline, and has been developed collaboratively by the American College of Radiology (ACR) and the American Society for Neuroradiology (ASNR). It is estimated that the number of people with dementia, 36.5 million worldwide in 2010, will increase to 65.7 million in 2030 and to 115 million in 2050. Four primary neurodegenerative etiologies of dementia have been defined: Alzheimer disease (AD), vascular dementia, frontotemporal dementia (FTD), and dementia with Lewy bodies (DLB). Alzheimer disease is the most common form of dementia, accounting for approximately 60%–80% of all cases. Indications for FDG and amyloid brain PET and qualifications for personnel are discussed in this practice parameter. Copyright © 2016 Wolters Kluwer Health, Inc. All rights reserved.
