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).

PET-CT scans combine structural and functional imaging to detect diseases early. This technology improves diagnosis accuracy ...

The use of extremely low amounts of radioactive material as diagnostic "tracers" in cancer imaging is not new, but researchers are continually working on new chemistries to make these radiotracers ...

Get Instant Summarized Text (Gist) A novel PET tracer, ¹⁸F-PDE-1905, enables high-quality imaging of brain inflammation by specifically targeting PDE4B, an enzyme regulating microglial activation.

Jeremie Calais, MD, MSc: The principle of nuclear medicine, and that’s the same for PET scan imaging, is that you receive an intravenous injection, a tracer. We call it a tracer because you can trace ...

When getting a PET scan, a radioactive tracer is injected into the bloodstream, which is taken up by the targeted tissue and emits a signal that the PET scanner detects.

Pinpointing who will and won’t get Alzheimer’s disease is tricky for doctors, but new research suggests it may soon get easier—for some people. Scientists discovered that a certain type of brain scan ...

A novel PET radiotracer developed at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital is able for the first time to reveal epigenetic activity -- the process that ...

The researchers re-examined data from a previous study (J. Nucl. Med. 10.2967/jnumed.114.147454), compiling PET scans from eight FTD patients, 10 cognitively normal controls and 10 patients with ...

A positron emission tomography (PET) scan is an imaging technique that uses small amounts of radioactive substances. Doctors may use PET scans in chemotherapy treatments for cancer. PET scans help ...

Dear Doctors: My wife is 59 years old. She had COVID-19 but recovered. A recent chest X-ray shows a white patch on her lung. She doesn’t have a cough or a fever, and her pulmonologist wants her ...

During a nuclear stress test, you’ll be injected with a radioactive dye called a tracer. Some of this tracer will remain in your system for a time after the test. A nuclear stress test is a type ...
