Tau proteins play an important role in Alzheimer's disease. Tau helps to stabilize neurons in the brain, but in Alzheimer's disease, tau proteins can misfold and tangle inside neurons. These tangles ...

PSMA PET scans significantly enhance detection and staging of prostate cancer, improving patient stratification and survival outcomes. Three FDA-approved PSMA PET scans are available, aiding in both ...

Researchers use AI and postmortem tissue to reveal that tau PET scans are often influenced by iron and neuroinflammation rather than tau tangles alone.

PET scans can detect amyloid plaques and tau tangles in the brain, which are often early signs of Alzheimer’s disease. But they’re not enough on their own to make a diagnosis. Alzheimer’s disease is ...

PET scans were helpful in determining which patients with HER2-positive early breast cancer may be able to skip chemotherapy. Treating patients with HER2-positive early breast cancer based on positron ...

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 ...

A new study from Brigham and Women's Hospital suggests that positron emission tomography (PET) brain scans could reveal hidden inflammation in patients with multiple sclerosis (MS) who are being ...

Dr George Owiti, a radiographer at Kericho County Hospital examines the Chest CT results of a patient admitted to the hospital. [James Wanzala, Standard] Despite recent breakthroughs that have ...

A heart PET scan is a noninvasive imaging test that uses a small amount of radiation. It helps doctors understand how the heart functions and whether it is healthy. Cardiac or heart PET scans create ...

Researchers used a novel PET tracer to visualize how ketamine alters AMPA receptor distribution in the brains of patients with treatment-resistant depression. Receptor density increased in cortical ...

Tau proteins play an important role in our normal brain function, mainly by helping to stabilize neurons in the brain. But in Alzheimer’s disease, tau proteins can misfold and tangle inside neurons.
