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 ...

Positron emission tomography (PET) is a sophisticated medical imaging technique. It uses a radioactive tracer to pinpoint differences in tissues on the molecular level. A whole-body PET scan can ...

When Daniel Gibbs, M.D., enrolled in an Alzheimer’s study at UC San Francisco almost a decade ago, researchers needed access to a secure government facility just to confirm that he had the disease.

Positron emission tomography (PET) scans can detect cancer earlier than other imaging tests. But some types of cancer are harder to detect on a PET scan. In particular, they may miss cancers that ...

A head-to-head comparative study of multiple imaging modalities suggests that positron emission tomography (PET) is the most accurate noninvasive test for the detection of myocardial ischemia. In a ...

A positron emission tomography (PET) scan is a diagnostic tool that examines body tissue functioning, such as blood flow, oxygen use, and sugar metabolism, to help doctors diagnose and treat disease.

The Foresight CLARITY test offers greater prognostic accuracy than PET/CT scans in large B-cell lymphoma by detecting ctDNA-MRD negativity, indicating better patient outcomes. ctDNA-MRD testing showed ...

Blood tests for Alzheimer’s disease are now so accurate that a positive result, on its own, is reason enough for people who are suspected of having AD to start immunotherapy. So proffered Suzanne ...
