Single Photon Emission Computed Tomography (SPECT) is a medical imaging technique that uses radioactive tracers to produce detailed images of internal organs, tissues, and bones. SPECT can help diagnose a range of medical conditions, including heart disease, cancer, and neurological disorders. However, there are several synonyms for SPECT, including single-photon emission tomography, gamma camera tomography, isotope scanning, and nuclear medicine imaging. Each of these terms refers to the same imaging technique, but may be used interchangeably depending on the context and the medical professional using the term. Regardless of the name, SPECT remains a vital tool in modern medicine for diagnosing and treating a variety of health conditions.
