DaTscan Imaging May Improve Dementia Dx

March 21, 2013

Differential diagnosis of dementia in patients with equivocal clinical presentations may be sharpened with an imaging technique recently approved for other purposes, a researcher said here.

SPECT imaging with a radioactive iodine-based tracer -- sold under the name DaTscan -- distinguished patients with Lewy body dementia and non-amnestic mild cognitive impairment (MCI) from those with Alzheimer's disease and amnestic MCI in a pilot study, said Bradley Boeve, MD, of the Mayo Clinic in Rochester, Minn.
