PET is widely employed in the clinic to track molecules within the body with high sensitivity. Currently, the vast majority of PET scans are performed using the radiotracer 18F-FDG to image tumours. But according to Charalampos (Harry) Tsoumpas, a lecturer in medical imaging at the University of Leeds, PET has a lot more to offer when it comes to clinical applications. “When PET was combined with CT, that was a big breakthrough that changed clinical practise,” said Tsoumpas. “But I believe that molecular imaging is just starting.” {read more here}

In an article published in the January 2017 issue of “The Journal of Nuclear Medicine,” researchers assert that exposure to medical radiation does not increase a person’s risk of getting cancer. The long-held belief that even low doses of radiation, such as those received in diagnostic imaging, increase cancer risk is based on an inaccurate, 70-year-old hypothesis, according to the authors. {read more here}
