First, let's get a bit of the jargon down. The playing surface in curling is called the sheet. Sheet dimensions can vary, but they're usually around 150 feet long by about 15 feet wide. The sheet is covered with tiny droplets of water that become ice and cause the stones to curl, or deviate from a straight path.
RE: FDG Uptake Explanation - PET SCAN. uptake is the amount of radioactive sugar that the cells are using for metabolism. It is possible to have a positive area on PET that is not cancer. Thats why its important to compare one scan to the next to see if there are changes.
FDG PET scan (coronal view).There is increased activity seen in the neck and shoulder muscles. Moderate uptake is also seen in the psoas muscles in this patient with scoliosis (arrows) [Image courtesy of Centre for Molecular Imaging, Peter MacCallum Cancer ...n summary; FDG will localise to any part of the body where there is high physiologic activity. Basic to the proper interpretation of PET CT scans is a clear understanding of the normal variants of uptake and awareness of the benign processes that are FDG avid to avoid potential pitfalls in image interpretation.
