JUL 13, diagnostic imaging: DOGgraphy

Authors' Note:   The confusing terminology for advanced, i.e. 3D medical imaging, uses acronyms that may be historically based or poorly explained. The development of a method of imaging known as ‘DOGgraphy’ is apocryphal. 

CAT: computerized axial tomography, X-ray imaging of a body section; better described in modern terms as ‘x-ray CT’
PET: positron (dual-photon) emission tomography; a Nuclear Medicine technique involving prior injection of a positron-emitting radionuclide ('isotope'); becoming an important modality in cancer assessment
Holography: processing of fields of light or other radiation scattered from objects; well developed with lasers, but with limited current application in medical imaging.
