New PET scanner halves radiation dose and fits inside an MR scanner

So you’re unlucky enough to be hit with the real C-word: cancer. That sucks. But what can be worse is that many current medical scanning techniques come with large levels of radiation. The current practice of combining PET (Positron emission tomography) and CT (computerized tomography) scans produces good images, but the cost is high: a dose of radiation ten times the background amount the average human gets in a year. And that’s just one scan. Many cancer patients have to endure multiple scans. A new PET scanner from physicists at the University of Oslo (UiO) cuts the radiation dose in half and is also small enough to fit inside an MR scanner. Although it was developed for animals, the researchers say it could be easily adapted for human clinical examinations.
