The FDA approved Netspot, the first kit for the preparation of gallium Ga 68 dotatate injection, a radioactive diagnostic agent for PET scan imaging, according to an agency press release.  This radioactive probe will help locate tumors in adult and pediatric patients with somatostatin receptor positive neuroendocrine tumors. Ga 68 dotatate, a positron emitting analogue of somatostatin, works by binding to the hormone. {read more here}

A new dedicated positron emission mammography (PEM) device was put through its paces by European researchers in an article in the June issue of the American Journal of Roentgenology. While the PEM system excelled at identifying lesions smaller than 1 cm, its limited field-of-view could be an issue, they found. {read more here}

The effort to find ways to detect and diagnose preclinical Alzheimer’s disease (AD) has taken a big step forward with the use of positron emission tomography (PET), a “nuclear medicine” for imaging processes in the body, when PET is used with a special ‘tracer’ that binds to the amyloid plaques in the brain that are a characteristic cause of AD. {read more here}
