If your doctor suspects you have cancer, to know definitively you typically need a full-body PET or CT scan – which exposes you to high levels of cancer-causing radiation, roughly the equivalent of 750 chest X-rays per scan.

By giving patients an iron supplement to enhance the visibility of tumors and sticking them in an MRI machine – which uses no radiation – they were able to spot tumors as effectively as the traditional technique.
