FDGbased

FDGbased refers to the use of fluorodeoxyglucose (FDG) in medical imaging, primarily Positron Emission Tomography (PET). FDG is a radioactive glucose analog that is injected into the bloodstream and taken up by cells. Cells with higher metabolic activity, such as cancer cells, tend to absorb more FDG. This uptake is then detected by the PET scanner, allowing for the visualization and characterization of tissues with abnormal metabolic rates. FDG-PET is a widely used diagnostic tool in oncology for detecting cancer, staging disease, monitoring treatment response, and identifying recurrence. Beyond cancer, FDG-PET has applications in neurology for assessing conditions like Alzheimer's disease and epilepsy, and in cardiology for evaluating myocardial viability. The "based" in FDGbased signifies that the imaging technique or diagnostic approach relies on the principles of FDG uptake and detection. This method provides functional information about tissues, complementing anatomical details obtained from other imaging modalities like CT or MRI. The interpretation of FDG-PET scans requires careful consideration of physiological FDG distribution to avoid false positives and negatives.
