The National Institute of Standards and Technology (NIST) has developed prototype calibration tools for an experimental medical imaging technique that offers new advantages in diagnosing and monitoring of certain cancers and possibly other medical conditions.

Water diffusion measurements with MRI could decrease false-positive breast cancer results and reduce preventable biopsies, according to a new study published online in the journal Radiology. Researchers said the technique also could improve patient management by differentiating high-risk lesions requiring additional workup from other non-malignant subtypes...
