QCT scans can measure bone mineral density and muscle mass. metabolism of the bone is working. Scanning the whole skeleton helps in diagnosing a wide range of bone disorders, including: Although the test relies on radioactive tracers to produce the images, these tracers produce little radiation exposure less than a CT scan. Nuclear imaging involves using small amounts of radioactive substances (radiotracers), a special camera that can detect the radioactivity and a computer to see structures such as bones inside the body. Does a PET scan always mean cancer? Does uptake on a bone scan mean cancer? Defects in uptake in the bone may be seen with a number of malignancies, typically lung cancer and breast cancer and occasionally in myeloma. Read More Created for people with ongoing healthcare needs but benefits everyone. unlocking this expert answer. UNCOMMON CAUSES 1. look for electromagnetic radiation in those energy ranges. A CT or PET scan may be more helpful to identify signs of this type of cancer. Swelling. Increased radio tracer uptake means the area had increased metabolic activity. Although lighter cold spots are abnormal, they typically represent conditions that are less serious than those represented by darker hot spots. 3 & 4. It is also known as the dose uptake ratio (DUR).

This definition was used in an attempt to separate patients with thyroiditis, which usually manifests with diffuse FDG thyroid uptake (,14), from those with malignancy, which usually manifests with focal FDG thyroid uptake (,15). In patients who have undergone recent radiation therapy, 812 weeks should elapse before an FDG PET study to avoid false-positive findings of radiation-induced esophagitis. Cold spots and hot spots can appear simultaneously on a bone scan and represent different but concurrent diseases or conditions. Tiny amounts of radioactive materials (tracers) are injected into a vein in the hand or arm. The prevalence of tumors of the rib bones ranges from 3 to 8% depending on the series [1], [2].
