Spect research

Since the 1980s, there have been thousands of scientific papers on brain SPECT imaging for evaluating many psychiatric and neurological disorders. The Amen Clinics' research library contains our own scientific research along with abstracts of thousands of studies from the U.S. and around the world.

The diagnostic utility of 99mTc-HMPAO SPECT imaging: a retrospective case series from a tertiary referral early-onset cognitive disorders clinic

BACKGROUND/AIMS: Patients with early-onset dementia (EOD) often present atypically, making an accurate diagnosis difficult. Single-photon emission-computed tomography (SPECT) provides an indirect measure of cerebral metabolic activity and can help to differentiate between dementia subtypes. This study aims to investigate the clinical utility of SPECT imaging in the diagnosis of early-onset Alzheimer's disease.

METHODS: All patients attending a tertiary referral clinic specialising in EOD between April 2012 and October 2013 were included in the study. Statistical analysis of SPECT patterns with clinical diagnoses, Addenbrooke's Cognitive Examination version 3 scores, and magnetic resonance imaging (MRI) atrophy was undertaken.

RESULTS: The results demonstrated a highly significant association between SPECT hypoperfusion patterns and clinical diagnoses. SPECT changes were demonstrated more frequently than MRI atrophy.

CONCLUSIONS: The results suggest that SPECT imaging may be a useful adjunct to clinical evaluation and a more sensitive biomarker than standard structural imaging.
