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.
Cancerous cells multiply more rapidly than normal cells, so they are more active. A positron emission tomography (PET) scan creates images of cell activity, using standardized uptake value (SUV) as a measurement. SUV describes the level of activity in a particular spot compared to activity elsewhere in the body. An SUV reading of 1 is baseline or normal celluar activity.
