SPECT is a single-photon emission computed tomography (CT) scanner, commonly known as an ECT test. It is used to make a diagnosis by injecting a contrast agent (radionuclide) intravenously and observing the distribution of the agent in the body to determine the functioning of the organs and the characteristics of the disease. Usually SPECT is fused with CT in the same machine, also known as SPECT/CT, to realize the same machine image fusion of functional image and anatomical image, which has the characteristics of high sensitivity, good resolution, easy to use, stable performance and so on.
Main Clinical Applications
Because of the lack of clarity of SPECT imaging, single SPECT imaging has gradually been replaced by SPECT/CT, which has become one of the most advanced medical imaging equipments for human beings, and is an ideal tool for in vivo diagnosis of diseases and research on the development of new medicines.?
Advanced medical equipment utilizing the SPECT principle can measure and display the biological activities of cells and molecules, such as GE's SPECT system, which combines diagnostic-grade multilayer CT with the composite imaging equipment SPECT-CT and PET-CT systems, which can accurately locate the location, nature and extent of lesions.SPECT imaging has an important role in clinical practice, and can be used in the following ways aspects of tomographic detection and obtaining three-dimensional images.
