This information may also be useful for decision making when allocating resources dedicated to the health care system, a critical issue that is especially important for the development of nuclear medicine in developing countries. This report presents an overview of clinical applications of SPECT/CT and a relevant source of information for nuclear medicine physicians, radiologists and clinical practitioners. Large numbers of people could therefore benefit from this shift all over the world. It has been reported that moving from SPECT alone to SPECT/CT could change diagnoses in 30% of cases. Clinical applications with SPECT/CT have started and expanded in developed countries. It may also be used as a one-stopshop for various diseases. However SPECT/CT is not just advantageous in oncology.
SPECT/CT, a hybrid image, precisely identified where the surgeon should operate. For example, in the case of a patient with metastatic thyroid cancer, neither SPECT nor CT alone could identify the site of malignancy. SPECT/CT has proven to be valuable in oncology. Integration of X ray computed tomography (CT) into SPECT has recently emerged as a brilliant diagnostic tool in medical imaging, where anatomical details may delineate functional and metabolic information. Single photon emission computed tomography (SPECT) has enabled the evaluation of disease processes based on functional and metabolic information of organs and cells. New tracers are spreading out the spectrum of clinical applications and innovative technological solutions are preparing the way for yet more modality marriages: hybrid imaging.
