Positron Emission Tomography (PET) and Computer Tomography (CT) scans can help in determining and evaluating bone cancer. Combining PET with CAT scan enable physicians in finding the right area to do a biopsy or to determine if the cancer treatment is working. It can also aid in planning radiation therapy.
PET scan is an imaging technology that reveals parts of abnormal bone growth associated with tumors and other abnormalities. CT scan, on the other hand, uses X-ray and computer in creating images of body cross-sections.
When used in conjunction, a PET Bone scan helps detect metastatic bone disease and to check the effects of cancer treatment.
PET Bone scan is an imaging test that uses a radioactive substance called F-18 sodium fluoride to look for disease in the entire skeletal system. It is both sensitive and specific for the detection of lytic and sclerotic malignant lesions and can precisely differentiate malignant from benign bone lesions.
There is no special preparation required prior to having a PET Bone scan. Please be sure to drink plenty of fluids before and after the injection of the tracer. Please wear comfortable and warm clothing to the exam and do not wear jewelry or clothes with any metal buttons, underwire bra, or metal zippers. If you have had a prior PET/CT and or CT scan at another facility, you must bring a copy of that disc or discs. Plan to be in the PET/CT department for approximately 2 to 3hrs and please note that we advise patients to stay away from children and pregnant women for 12 to 24 hours following the time of injection. Please do not bring children or pregnant women with you to your appointment. We are extremely cautious in this regard; there are NO definite risks from this level of radiation.
During a PET Bone scan, a tracer is injected intravenously into the patient’s body. It would take approximately sixty to ninety minutes for the bones to absorb the radioactive material.
While waiting for the tracer to be absorbed by the bones, you will be asked to drink water, unless otherwise instructed by your doctor. This would lead to more frequent urination aimed at removing the radioactive material not collected in the bones.
Prior to the scan, you will be asked to empty your bladder before your scan. You will be asked to remove jewelry and other accessories that could get in the way. You then asked to lie flat on an exam table and moved into the PET/CT scanner, a huge machine with a round hole in the center. It would take roughly another hour for a whole-body scan to complete. You can go back to your normal routine including driving. While there are no side effects from the intake of the tracer, it is recommended that you drink lots of water to flush out the material from the body.
PET/CT Bone scans are used in assessing bone cancer. The combination of these two imaging technologies also helps specialists in finding the proper body area to perform a biopsy or determine if cancer treatment is functioning.
