PET/CT with the radiotracer 18F-FDG may have met its match at cancer detection in two new “FAPI” tracers based on gallium-68. The acronym stands for fibroblast activation protein inhibitor, and in a recent trial the new tracers equaled or bettered FDG PET/CT on image quality, required no fasting and yielded images in less time than FDG PET/CT.

In Ontario, Canada, it is illegal to cremate a patient who has received the radiation treatment brachytherapy. Radiation experts are now calling on the province to change the law, according to a report by CBC News.

Measuring the effectiveness of treatment in metastatic melanoma patients is difficult, but a study published in the March issue of the Journal of Nuclear Medicine found 18F-FDG PET/CT could accurately monitor immunotherapy with ipilimumab in these patients.

The upcoming vote on whether the U.K. will leave the European Union has prompted the Royal College of Radiologists (RCR) to warn doctors of a potential delay in receiving drugs used to detect and treat cancer, the BBC reported.

The research team also found combining 4D CT and technetium-99m sestamibi SPECT/CT did not improve diagnostic performance compared to 4D CT alone.

The American College of Radiology (ACR) and American Association of Physicists in Medicine (AAPM) released a joint statement Monday, March 5, to quell potential fears sparked by a recent research letter investigating the presence of radioactive materials in cremated bodies.

The electromagnetic interference (EMI) emitted by cell phones may negatively impact gamma cameras, according to results of study published in the Journal of Medical Imaging and Radiation Sciences. But does that necessitate an outright ban?

The body of a 69-year-old male patient treated with lutetium-177 dotate contaminated an Arizona crematorium after radioactive material was found on equipment there, Tech Times reported. The incident has raised questions about the postmortem management of radiopharmaceuticals.

The Department of Energy’s National Nuclear Security Administration (NNSA) has chosen four U.S. companies to begin negotiations with in an effort to produce Molybdenum-99 (Mo-99) without the use of highly enriched uranium.

A novel PET/CT imaging agent—18F-GP1—produced a high-quality image and yielded a high detection rate for diagnosing acute venous thromboembolism (VTE), reported researchers of a study featured in the February issue of The Journal of Nuclear Medicine.

Stereotactic ablative body radiation therapy (SABR) nearly doubled the overall survival of patients with inoperable stage I lung cancer compared to standard radiotherapy, according to results of a multi-center phase III trial published in the Lancet Oncology.

A molecular imaging technique using PET technology may improve how the efficacy or failure of hormone therapy is measured for breast cancer patients, according to research published online in the February issue of The Journal of Nuclear Medicine
