PET scans can light up tumors in the body and help doctors determine if they are cancerous or benign (noncancerous). The results of a PET scan help guide medical decisions. A PET scan is a type of ...

USC researchers have found a promising new brain scan marker that could better detect Alzheimer’s risk — but only for some. The tau-based benchmark works in Hispanic and White populations when ...

The study revealed that plasma eMTBR-tau243 explains about 56% of the variation seen in brain tau PET scans, performing better than other blood markers. It also strongly correlates with brain ...

The scan will take 45 minutes to 2 hours, but the results could take weeks. If your results come back quickly or take a long time, it’s helpful not to make assumptions about what that time frame ...

This new scan finds Alzheimer’s risk years in advance. Learn what the research means for early detection and brain health—and if the test applies to you.

New test could detect Alzheimer’s sign a decade before it shows up on brain scans By Tracy Swartz Published Feb. 20, 2025, 6:00 a.m. ET ...

PET is a scan that uses a tracer to show tumor activity. Research published in 2017 indicates that lymphoma cells are particularly responsive to a tracer called fluorodeoxyglucose (FDG).

For example, if your PET scan costs $5,000 before coverage, you’d pay $1,000, and Medicare Part B will pay the remaining 80%, or $4,000 in this example. Costs with private insurance plans ...
