  A PET scan is a medical imaging technique that uses radioactive substances, called radiotracers, to visualize and measure changes in  metabolism  (the chemical processes that take place in cells to keep the body functioning normally). This includes evaluating where blood flow is being directed, where energy is being consumed, and how waste products are being eliminated. 4 A PET scanner is comprised of a table that moves in and out of a doughnut-shaped or tube-shaped port that houses the detection apparatus. 5 PET scans have several different medical uses, including: 6 Diagnosis and monitoring of cancer, including the spread ( metastasi ) of cancer to other parts of the body, including bone Diagnosis and monitoring of brain disorders, such as tumors,  epilepsy , and  Alzheimer's disease Diagnosis and/or monitoring of cardiovascular problems, such as  coronary artery disease (CAD) , heart attacks, and  heart failure Different radiotracers, deliver...

  Diagnosis Imaging tests can help determine the location and size of bone tumors, and whether the tumors have spread to other parts of the body. The types of imaging tests recommended depend on your individual signs and symptoms. Tests may include: Bone scan Computerized tomography (CT) Magnetic resonance imaging (MRI) Positron emission tomography (PET) X-ray Needle or surgical biopsies Your doctor may recommend a procedure to remove a sample of tissue (biopsy) from the tumor for laboratory testing. Testing can tell your doctor whether the tissue is cancerous and, if so, what type of cancer you have. It can also reveal whether the tumor cells are growing quickly or slowly. Types of biopsy procedures used to diagnose bone cancer include: Inserting a needle through your skin and into a tumor.  During a needle biopsy, your doctor inserts a thin needle through your skin and guides it into the tumor. Your doctor uses the needle to remove small pieces of tissue from the tumor. Surg...
