Amyloid plaque burden in the brain may be estimated indirectly via retinal or ocular lens imaging techniques, which would be easier than the expensive PET scans now available, researchers said this week.
In one study, led by Shaun Frost, MSc, BSc, of the Australian research organization CSIRO, retinal amyloid measured by a fluorescence-based scan correlated with results of brain PET scans in 40 volunteers using the Pittsburgh Compound B (PiB) amyloid tracer with an R coefficient of 0.762 (P<0.0001).
