Description
Positron Emission Tomography (PET) scans help diagnose and monitor cancer, heart disease, and brain disorders; in China, costs typically range ¥300–¥700 (US$2,000–$5,000), with ChinaMedicalHub assisting with hospital booking and interpreter support.
Main Uses
The primary purposes and applicable scenarios for a PET scan include: Detecting cancer and assessing its spread, Evaluating the effectiveness of cancer treatment, Diagnosing neurological disorders such as Alzheimer's disease, Assessing heart health and diagnosing cardiovascular diseases, Investigating unexplained fevers or infections, Guiding biopsies and other surgical procedures
Normal Range
For a Positron Emission Tomography (PET) scan, there is no specific 'normal' range of values as it is an imaging test. The results are interpreted based on the visual and quantitative analysis of the radiotracer uptake in different tissues. A normal PET scan shows uniform distribution of the radiotracer with no areas of abnormally increased or decreased uptake.
Low Values - Possible Causes
Low uptake in a PET scan can be caused by: Reduced blood flow to the area, Tissue necrosis or death, Previous treatments like radiation therapy, Low metabolic activity in benign conditions, Technical issues during the scanning process
High Values - Possible Causes
High uptake in a PET scan can be caused by: Malignant tumors, Inflammation or infection, Active healing processes, Hypermetabolic states such as hyperthyroidism, Physiological variations in certain organs like the brain and heart
