History and Principles of Hybrid Imaging

  • James A. Patton


Positron emission tomography (PET) and single photon emission computed tomography (SPECT) systems are used to image distributions of radiopharmaceuticals in order to provide physicians with physiological information for diagnostic and therapeutic purposes. However, these images often lack sufficient anatomical detail, a fact that has triggered the development of a new technology termed hybrid imaging. Hybrid imaging is a term that is now being used to describe the combination of x-ray computed tomography (CT) systems with nuclear medicine imaging devices (PET and SPECT systems) in order to provide the technology for acquiring images of anatomy and function in a registered format during a single imaging session with the patient positioned on a common imaging table. There are two primary advantages to this technology.
