What Does Cancer Look Like On A Pet Scan
Bright: Pet scans take advantage of the thought that most caners are more metabolically active than the normal tissues around them. This makes the cancers show up as "hot" or "bright" on pet imaging. There are other areas that are "bright" normally as well, like brain and to some extent liver. However, when using pet for breast cancer staging one is looking to see if there are unexpected bright areas. ...Read moreSee 1 more doctor answer
Pet scans most often use a radioactive form of glucose, the energy source for most of the cells in our bodies. The pet scanner can detect and measure how much of the radioactive glucose analog, f-18 fdg, is in a particular organ or region. The areas using more glucose are hyper metabolic and generally more worrisome. Our brains and sometimes hearts prefer glucose as food, making ...Read more
Lost about 50 pounds and have tenderness on right side and small lump. Doctor ordered pet scan also said it looks like cancer thank you in advance

Yes and no: Areas with cancer are usually hypermetabolic in a pet scan due to the increased uptake of the radioactive glucose by cancerous cells. Looking at an FDG pet scan alone, you can grossly see "dark" areas in the brain, heart, kidneys and bladder and these are due to physiologic distribution/excretion of fdg. Not all "dark" is cancer and cancer is often but not always "dark". ...Read moreSee 2 more doctor answers

PET is not 100%: The distribution and intensity of hyper-metabolic activity appearance on a pet/ct scan could be abnormal and may represent malignancy but is not pathognomonic and may also represent inflammation, infection or granulomatous disease. If biopsy is correctly done, results of direct tissue are usually more certain. However, short interval follow-up with pet/ct is often recommended. ...Read moreSee 1 more doctor answer
