'A diagnostic revolutionary' -- the legacy of Godfrey Hounsfield
CT has become a vital form of medical imaging that is ubiquitous throughout the world, offering powerful insights into the human body. Most of the credit for the development of CT goes to Sir Godfrey Hounsfield, the U.K. scientist who developed the first CT scanner in 1971.

Nuclear medicine physicians must change to survive
While nuclear medicine is not in imminent danger of extinction, it may need to reinvent itself for the future, according to the president of the British Nuclear Medicine Society. In particular, nuclear medicine physicians need to shed their self-image as purely imaging-based physicians to become more involved in clinical areas.
