Novel Tracer Promises Better Alzheimer's Picture

July 17, 2012

A second-generation beta amyloid tracer for PET scans aimed at measuring brain pathology in Alzheimer's disease patients combines the best features of the two current types of agents, a researcher said here.

The investigational agent, called AZD4694, produced brain images in a clinical trial that were virtually identical to those obtained with Pittsburgh Compound B (PiB) in a head-to-head study, said Christopher Rowe, MD, of Austin Health in Melbourne, Australia.
