Increased activity on pet scan
WebJul 28, 2024 · PET: PET scan usually refers to PET-CT scan where a CT scan is fused with a PET scan for interpretation. The CT is helpful for anatomic localization of uptake on PET. The PET portion of the exam shows metabolic activity (glucose uptake). Glucose is a nonspecific tracer and can be taken up in inflammatory, infectious, or malignant conditions. WebCalculation of weighted two-point correlation function. Continuous-valued images such as an amyloid-PET can be characterized with multiple two-point correlation functions, one for each voxel value. 20 However, typical amyloid-PET images have more than a few activity values. Therefore, such an approach would require computation of a large number of S 2 …
