What are the disadvantages of a PET scan?
Limitations of a PET Scan A PET scan is less accurate in certain situations: Slow-growing, less active tumors may not absorb much tracer. Small tumors (less than 7mm) may not be detectable. High levels of blood sugar can cause the cells to absorb this normal sugar rather than the radioactive, injected kind.
Are body scans safe?
At the low doses of radiation a CT scan uses, your risk of developing cancer from it is so small that it can’t be reliably measured. Because of the possibility of an increased risk, however, the American College of Radiology advises that no imaging exam be done unless there is a clear medical benefit.
What does a full body scan detect?
The Total Body CT scan analyzes three major areas of the body: the lungs, the heart, and the abdomen/pelvis. The lung CT can detect early, potentially malignant nodules. In the heart, the scan can detect aortic aneurysms and calcium deposits within plaque in the coronary arteries.
Do all cancers show up on a PET scan?

What is the best scan to detect cancer?
CT (computed tomography) and MRI (magnetic resonance imaging) are both used to diagnose and stage cancer. Many people do not know the difference between the two methods or why one might be selected over the other.
What does a CT scan look like with cancer?
CT scans show a slice, or cross-section, of the body. The image shows your bones, organs, and soft tissues more clearly than standard x-rays. CT scans can show a tumor’s shape, size, and location. They can even show the blood vessels that feed the tumor – all without having to cut into the patient.
Why would a doctor order a full body scan?
Are whole-body scans ever recommended? Your doctor may order the test if you already have cancer, to see if it has spread. The test may also be helpful in an emergency. Doctors may use the test to help examine a major injury.
How does cancer kill you in the end?
