The test will be a cheaper and more accessible alternative to currently available diagnostic tools, researchers say.

An imaging agent reveals aggregated tau protein in the brain during PET scans and could improve the diagnosis of neurodegenerative diseases, particularly tauopathies.

The Stanford Medical School professor’s research aided the development of positron emission tomography (PET) reporters to identify disease.

Conflicting results on the existence of new neurons in adults have researchers designing new ways to identify and count neuronal progenitors—and finally get to the bottom of neurogenesis.

A study hints that it might be possible to diagnose chronic traumatic encephalopathy, a neurodegenerative disease associated with frequent head injuries, while patients are still living.

The new technology could allow for new and improved applications in both medicine and research.  

For the first time, researchers visualize histone deacetylase in the brains of healthy volunteers.

Dopamine receptors in the cortex orient the brain toward the task at hand.

Overall brain metabolic rate can distinguish between pathological states of human consciousness, a study shows.

An inspiring lecturer turned Marcus Raichle’s focus from music and history to science. Since then, he has pioneered the use of imaging to study how our brains function.

For neuroscientists, experimental results converge to help crack the case of how the brain functions.

Researchers find that positron emission tomography scans can help determine the degree to which some vegetative patients retain consciousness.

In living humans, researchers image snarls of tau, one of the proteins associated with Alzheimer's disease.

Techniques for watching tumors do their thing

Biomarkers of Alzheimer’s disease are ready for widespread use in clinical trials.

How to follow stem cells transplanted into living tissue.

Although most of the studies now occurring in the In Vivo Cellular and Molecular Imaging Centers (ICMICs) are focused on basic animal research, investigators aren't wasting any time in moving the power of in vivo molecular imaging to human patients.
