Full-body scans use different technologies, including magnetic resonance imaging (MRI), computed tomography (CT) or positron emission tomography (PET), according to the Dana-Farber Cancer Institute.

They can be life-saving but radiation from the scans also contributes to cancer risk. The authors of a new study estimate ...

Full-body scans use different technologies, including magnetic resonance imaging (MRI), computed tomography (CT) or positron emission tomography (PET), according to the Dana-Farber Cancer Institute.

Cutting out unnecessary imaging scans could reduce those emissions by as much as 129 kilotons, researchers said. Unnecessary ...
