PET scans are considered to be safe. The main risk arises from exposure to radiation during the test. That exposure is small, equal to about three years’ worth of natural background radiation.

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).

Positronium formed during PET scans could detect hypoxic tumours The researchers observed visible and significant differences between the o-Ps lifetime in cancerous and healthy tissues, with mean ...

Hybrid imaging with SPECT and coronary CTA yielded a diagnostic accuracy of 76%, while the combination of PET and CTA resulted in an accuracy of 84%; neither approach improved on PET alone. “Previous ...

Dual time-point 18 F-FBB PET scans were conducted during the first 10 minutes of the procedure and again from the 90-to-110-minute mark. Researchers performed quantitative and visual analyses of ...

Positron emission tomography (PET) scanning differs from most other medical imaging techniques because it is used to look at function inside the body, rather than structure. In this video interview, ...

PET scans can identify amyloid plaque, a telltale sign of Alzheimer's disease. Evan Vucci/AP O ne morning in 2012, my wife Geri looked in the mirror and failed to recognize her own face.

Combined PET/MR scans may mean using optical tracking equipment to correct head motion is no longer necessary. According to a recent study, PET/MR can benefit patients with Alzheimer’s disease.
