The researchers used small animal positron emission tomography (PET) imaging to assess the activity of kappa opioid receptors in the animals’ brains, and were able to demonstrate that when rats were in pain, their kappa opioid receptors were very active in a part of the brain called nucleus accumbens, which is linked to emotion. {read more here}

Using PET/CT for follow-up at a later interval than what’s recommended by existing guidelines can potentially adjust the management of patients who have been treated for oropharyngeal squamous cell carcinoma (OPSCC), according to a study published online March 5 in the American Journal of Roentgenology. {read more here}

Researchers have identified two new nuclear medicine tracers that make it easier to diagnose and potentially treat cancer. A proof-of-concept investigation, published in the March issue of The Journal of Nuclear Medicine, reports that 68Ga-FAPI positron emission tomography/computed tomography (PET/CT) provides high-contrast images with quality equal to or better than that of the standard 18F-FDG imaging. {read more here}
