| positron emission tomography |
A PET scan creates an image of the body (or of biochemical events) after the injection of a very low dose of a radioactive form of a substance, such as sugar. The scan computes the rate at which the tumor is using the sugar. In general, high-grade tumors use more sugar than normal and low-grade tumors use less. PET scans may also be used to see how well the tumor is responding to treatment
