SPFHs

SPFHs, or Single-Photon Emission Computed Tomography/Computed Tomography, is a hybrid medical imaging technique. It combines the functional information from SPECT imaging with the detailed anatomical information from CT scanning. SPECT uses radioactive tracers that emit gamma rays, which are detected by a rotating gamma camera to create cross-sectional images of the body's internal organs and tissues. CT, on the other hand, uses X-rays to generate detailed anatomical slices. By fusing these two datasets, SPFHs allows clinicians to visualize both the physiological processes occurring in a region and its precise anatomical location simultaneously. This integrated approach enhances diagnostic accuracy for a wide range of conditions. For example, in oncology, SPFHs can help identify tumors, assess their metabolic activity, and determine their spread. In cardiology, it can evaluate blood flow to the heart muscle and detect areas of damage. Neurology applications include assessing brain function and identifying neurodegenerative diseases. The radioactive tracer used in SPECT is chosen based on the specific organ or disease being investigated, targeting different biological processes like metabolism, blood flow, or receptor binding. The CT component provides the structural context, aiding in the accurate interpretation of the SPECT findings and helping to rule out artifacts.
