Researchers at Johns Hopkins Medicine have developed a PET imaging technique using a carbon-11-based radiotracer that confirmed an association between post-treatment Lyme disease syndrome (PTLDS) and widespread inflammation in the brain. {read more here}

With the help of PET scans, researchers have found women’s brains appear to be three years younger than men’s. The findings, published in Proceedings of the National Academy of Sciences, may explain why women remain mentally sharper longer than men. {read more here}

Researchers at the Wolfson Molecular Imaging Centre and the Sir Peter Mansfield Imaging Centre have reported on a new utility of the PET tracer florbetapir. They found that the tracer can distinguish frontotemporal dementia (FTD) from Alzheimer’s disease and the cognitively normal elderly. {read more here}

Sex differences in amyloid burden alone have not been reported in older adults. This may suggest that male-female differences appear downstream, after amyloid beta starts to accumulate, Sperling and colleagues observed. To study this, they evaluated two cross-sectional convenience samples of clinically normal individuals who received both tau and amyloid beta PET scans from January 2016 to February 2018. {read more here}
