Is A Bone Scan Necessary?

Why would a doctor order a bone scan?

Your doctor may order a bone scan if you have unexplained skeletal pain, a bone infection or a bone injury that can’t be seen on a standard X-ray.

A bone scan can also be an important tool for detecting cancer that has spread (metastasized) to the bone from the tumor’s original location, such as the breast or prostate..

Does a bone scan show osteoporosis?

Unlike ordinary X-rays, DEXA scans can measure tiny reductions in bone density. This makes it possible to diagnose osteoporosis in its early stages, before you break a bone. A DEXA scan also uses a low dose of radiation, which means the risks to health are much lower than with standard X-rays.

Is a bone scan the same as a CT scan?

A bone scan involves a small dose of ionizing radiation from the radiopharmaceutical injected into your vein, and also from the CT scan during the CT portion of SPECT/CT imaging.

What is the difference between a bone scan and a bone density test?

And the denser your bones, the stronger they generally are and the less likely they are to break. Bone density tests differ from bone scans. Bone scans require an injection beforehand and are usually used to detect fractures, cancer, infections and other abnormalities in the bone.

How should I dress for a bone scan?

Patients should not have had a barium study, radioisotope injection, or an oral or IV contrast material from a CT scan or MRI within 7 days prior to their DEXA exam. Patient should wear loose, comfortable clothing. Sweat suits and casual attire without zippers, buttons, grommets, metal hooks, or underwire bra.

What does a body scan tell you?

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.

Who needs a bone scan?

To detect conditions such as arthritis , benign bone tumors, Paget’s disease (a bone disorder, usually occurring in people over age 50, in which there is thickening and softening of the bones, and curving of the long bones), and avascular necrosis (death of bone tissue due to loss of blood supply to the bones)

Do you have to take your clothes off for a bone scan?

When you return the technologist will have you/your child remove clothing that has metal or other clothing fasteners like buttons or zippers. You will be given a hospital gown and/or pajama bottoms to wear if this is not possible. You will lie on an imaging table during the bone scan.

Can I drink coffee before a bone scan?

24 hours before your appointment: Do not do any strenuous exercise or deep tissue massage. Refrain from consuming any caffeine, including any decaffeinated products.

What is the difference between a bone scan and a PET scan?

Conclusions The difference between bone scan and PET/CT for detection of bone metastases may be attributable to the different mechanism. Bone scan depends on the osteoblastic response to bone destruction by tumor cells,and FDG-PET/CT detects the metabolic activity of the tumor cells.

What machine is used for a bone scan?

Gamma cameras and PET scanners are the 2 basic types of cameras used to image the radioactive decay from the radiotracers utilized in bone scintigraphy.

Can you have a CT scan and a bone scan the same day?

Bone Scan, Skeletal Imaging If a CT scan is scheduled for the same day, an IV line will be placed prior to the injection for the bone scan. You may not eat until after the CT scan is completed.

How long does it take to get a bone scan?

It takes pictures of the tracer in your bones. The technologist may ask you to change positions during the scan. This helps to get pictures from different angles. A whole-body bone scan takes about 1 hour to finish.

Does a bone scan show inflammation?

Bone scan is one of the most common and oldest examinations among all nuclear medicine procedures. It is used in the evaluation of benign bone disease like infection/inflammation and also is the standard of care for evaluating metastatic disease in the breast, prostate, and lung cancer.

Will a bone scan show disc problems?

Making a degenerative disc disease diagnosis can require additional tests. Bone scan: To help your surgeon detect spinal problems such as osteoarthritis, fractures, or infections (which can all be related to DDD), you may have a bone scan.

How accurate is a bone scan?

Ohta and colleagues compared PET and bone scan in evaluation of skeletal metastases in 51 patients with breast cancer and found that the sensitivity, specificity and accuracy of the bone scan were 77.7%, 80.9% and 80.3%, respectively.

What happens when you have a bone scan?

During a bone scan, a radioactive substance is injected into a vein that is taken up by your bones. You’ll then be monitored for several hours. A very small amount of radiation is used in the substance, and nearly all of it is released from your body within two or three days.

Will a bone scan show arthritis?

Many changes that show up on a bone scan are not cancer. With arthritis, the radioactive material tends to show up on the bone surfaces of joints, not inside the bone. But it can be hard to tell the difference between arthritis and cancer — especially in the spine.

What does a cold spot on a bone scan mean?

Areas that absorb little or no amount of tracer appear as dark or “cold” spots. This could show a lack of blood supply to the bone or certain types of cancer. Areas of fast bone growth or repair absorb more tracer and show up as bright or “hot” spots in the pictures.

How do you prepare for a bone scan?

Preparing for a Nuclear Bone Scan You can eat and drink as you usually would before your scan. You don’t have to do anything special to prepare. But certain things can interfere with the tracer, so tell your doctor if you have: Taken an over-the-counter medication containing bismuth (such as Pepto-Bismol)
