title: Nuclear imaging: new developments.
abstract: Tomographic images produced with very short-lived radioisotopes of basic biologic elements can provide a form of moving in vivo autoradiography that delineates the dynamic state of the body constituents. The nuclides must be used at the site of the cyclotron where they are produced, but the day may be at hand when such facilities will be common, at least in the larger teaching hospitals.
