Bone scan vs pet scan for cancer. In this post i will briefly blog about getting the biopsy results and about getting a pet scan. The glucose goes to the area of active cell growth. Oncologist #2 says that oncologist #1 had a bad idea.

Pet scans (positron emission tomography scans) are often done in conjunction with ct scans (computerized tomography scans) or mri scans (magnetic resonance imaging scans).
Doctors might also use a pet scan to assess heart and brain functioning. • a bone scan is able to detect cancer in bones when psa is as low as 10 ng/ml but is not able to detect cancer metastasis in other parts of the body, such as the prostate or lymph nodes. The reality is that you cannot rely on a ct scan (or ultrasound, mri, or blood test) to tell you if you have cancer.
If the result shows change or damage to your bones, you may need more tests. A pet scan uses small amounts of radioactive substances, called contrast materials, for contrast within the body. While it sounds scary, the tracer typically leaves your body a few hours after the scan.
I have widespread bone disease an the pet did not pick it up because it was stable. As i noted in the last post, the radiology doctor had let me know it would be three to five days until i got the biopsy results. Enables a high detection rate that is equal to or better than mri in the prostate bed.
Bone scan is a crude way of measuring active disease in bone. A pet scan is an expensive test. Pet/ct scans provide significantly more information than ct scans, and are far more reliable when diagnosing cancer.
In other words, since a pet scan takes images of disorders at the molecular level, it can help the physician detect abnormalities in the activity of the prostate’s tissue cells at its early stages. He said that i needed a bone scan and another ct, preferably with contrast to check this spot out. There are more sensitive tests available now.
Sunnysideup, actually, a pet is a nuclear medicine test. It does not pick up dead cells. Pet scans are most commonly used to detect or monitor cancer.

Deciding on the right scan. The specific use of a bone scan is to diagnose active bone diseases, such as osteoporosis, paget’s disease or the spread of cancer into the bone. A pet image can map the biological function of an organ, can detect subtle metabolic changes, determine if a disease is active or dormant, may be used to determine if a tumor is benign or malignant (malignant tumors have classic metabolic patterns), and may be used to stage certain types of cancer.
During this test, radioactive material is injected into a vein, and seeps in the bones and is detected with nuclear imaging, in order to reveal cell activity and function in the bones. This is because not all cancers are the same, and because some scans work better on certain parts of the body than others. So i'm headed for a bone scan soon, but probably with a ct without contrast.
A pet scan uses a tiny amount of radioactive material called a radiotracer, a camera and a computer to create images of the inside of your body.
