nuclear imaging
Isotope-based diagnostics
Nuclear imaging is a medical diagnostic technique that uses small amounts of radioactive materials to visualize organ function and structure.
Unlike X-rays, which show anatomy, nuclear imaging reveals how organs and tissues are working: The nuclear imaging scan showed reduced blood flow to the heart.
Common forms include PET scans and bone scans.
