Amyloid Imaging: Now Covered By CMS, With Major Caveats

On the heels of the final decision from CMS regarding coverage for amyloid imaging in late September, Molecular Imaging Insight talked with amyloid PET imaging expert Peter Herscovitch, MD, SNMMI 2013-2014 president elect in an exclusive interview to discuss the potential impact of the new climate of coverage in the near to distant future. The CMS coverage decision now allots one amyloid PET scan per patient in approved clinical trials, but it is not yet clear how these studies will proceed. He offers some key points of conversation for stakeholders in dementia imaging.
