To the Editor: Dr Silverman and colleagues1 found that positron emission tomography (PET) may predict progressive dementia and also establish a diagnosis of Alzheimer disease (AD). Although the results suggested that PET could be superior to clinical examination diagnosing AD, the analysis fails to answer several questions about the appropriate role for PET in the clinical decision-making process.
