In this technique, one or more of the atoms of the molecule of interest is substituted for an atom of the same chemical element , but of a different isotope like a radioactive isotope used in radioactive tracing.

Two scans of the same woman with a small tumor in her breast: The scan on the left is a traditional x-ray scan where the tumor is not visible, the scan on the right is using new technology where the tumor appears in blue Dr Mike Shere, breast specialist at Southmead Hospital, said: It is quick, safe, comfortable and cheap, and is already producing good images with high sensitivity.

This technology uses radio waves which are almost exactly the same as mobile phone frequency — and less energy.
