Abstract

Single-Photon Emission Computed Tomography-Computerized Tomography (SPECT-CT) is a new hybrid technique that offers new diagnostic capabilities in daily nuclear medicine practice due to the possible attenuation and/or scatters correction of the SPECT functional images and the availability of helpful anatomic information and that can be used as SPECT alone or as isolated CT. This technique not only allows acquiring fusioned anatomic and functional images at the same time but also, it greatly increases the sensitivity and accuracy of SPECT for particular clinical indications. Until now, SPECT-CT data have been mainly used in oncology and Cardiology, but now, many authors spread its use to many scan studies. SPECT-CT seems to increase diagnostic performances and to modify management of many patients. SPECT-CT the development will probably modify nuclear medicine practice and many studies have to be conducted to highlight consensual procedure guidelines. Daily practice shows indisputably the important contribution of this new nuclear adopted by physicians as by clinicians imaging technique.
