Compared to techniques such as X-rays and MRI, the use of radioactive materials for diagnostic imaging is comparatively unknown. However such images can provide very useful information about the function (as opposed to the structure) of all the major organs of the body, and the technique is important in many diagnoses.
This talk will start by looking at the basic physics used, the choice of radionuclides for both gamma and PET imaging and the operation of the detectors used. Examples of clinical images will show the wide range of uses of this technique and the way in which 3D images can be created. The most recent developments in this area are the combined SPECT/CT and PET/CT systems which allow simultaneous imaging of structure and function.
