Ionising radiation-free whole-body MRI in children and young adults with cancer

Researchers at Stanford University have tested an ionizing radiation-free staging method based on whole-body diffusion-weighted MRI and the iron supplement ferumoxytol as contrast agent in a pilot study in children and young adults with malignant lymphomas and sarcomas, published in Lancet Oncology in March 2014.

The study concludes that although 18F-FDG PET/CT, which is used as a comparing method, detects a slightly higher number of malignant lesions, the MRI-method is superior as it demonstrates a higher specificity and involves no ionizing radiation.

The MRI-technique is believed to have great potential  as an alternative to imaging methods involving ionizing radiation, not least among children and young adults who are especially sensitive to radiation exposure.
