11C-acetate

11C-acetate is a radioactive compound used in medical imaging, specifically in positron emission tomography (PET) scans. It contains a form of carbon called carbon-11, which emits signals that can be detected by the scanner. When injected into the body, 11C-acetate is taken up by cells, especially those with high energy needs like cancer cells or the heart. This allows doctors to visualize and assess metabolic activity, helping in the detection and evaluation of tumors or heart conditions. Its short half-life (around 20 minutes) ensures rapid imaging and minimal radiation exposure.
