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.
Standardized uptake value. The standardized uptake value (SUV) is a nuclear medicine term, used in positron emission tomography (PET) as well as in modern calibrated Single Photon Emission Tomography (SPECT) imaging for a (semi)quantitative analysis. Its use is particularly common in the analysis of F]fluorodeoxyglucose (F]FDG) images of cancer patients.
