What are the 3 phases of a bone scan?
– Discussion: – initial dynamic images are aquired over the area of concern and then followed immediately afterwards by static images obtained over.
What is the meaning of bone scan?
A bone scan is a specialized radiology procedure used to examine the various bones of the skeleton. It is done to identify areas of physical and chemical changes in bone. A bone scan may also be used to follow the progress of treatment of certain conditions. A bone scan is a type of nuclear radiology procedure.
How do I read my bone scan results?
Understanding Bone Density Test Results
- A T-score of -1.0 or above is normal bone density. Examples are 0.9, 0 and -0.9.
- A T-score between -1.0 and -2.5 means you have low bone density or osteopenia.
- A T-score of -2.5 or below is a diagnosis of osteoporosis.
- The lower a person’s T-score, the lower the bone density.
What is the difference between a bone scan and a CT scan?
A CT scan is a high-resolution X-ray that gives detailed information about organ anatomy. A bone scan is a nuclear imaging test that aids in the diagnosis and tracking of several bone diseases. A CT scan uses a combination of X-rays and a computer to create images of the bones.
What does a dark spot on a bone scan mean?
Scan A shows hot spots (dark areas) in both knees, a sign of arthritis, and a possible fracture in the second toe of the right foot. Otherwise it shows normal bone metabolism.
Do you have to take your clothes off for a bone scan?
No special preparations are needed. You may be able to remain fully clothed, depending on the area of your body being scanned. But you’ll need to remove any clothes that have metal fasteners, such as zips, hooks or buckles. In some cases, you may need to wear a gown.
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.
How long does it take to get the results of a bone scan?
How soon will the scan results be available? A radiologist will interpret the images, write a report, and deliver the results to your doctor via the internal computer system. This process usually takes less than 24 hours.
What does an abnormal bone scan look like?
Results are considered abnormal when the scan shows darker “hot spots” or lighter “cold spots” in the bones. Hot spots describe places where an excess of radioactive substance has collected. Cold spots, on the other hand, are areas where it didn’t collect at all.
What does a bad bone scan look like?
What do bright spots on a bone scan mean?
Areas of fast bone growth or repair absorb more tracer and show up as bright or “hot” spots in the pictures. Hot spots may point to problems such as arthritis, a tumor, a fracture, or an infection.
What do bone scans look for?
Bone scan can provide early detection of primary cancer and cancer that has spread to the bones from other parts of the body. Bone scan can detect osteomyelitis, an infection of the bone or bone marrow. Bone scan helps monitor the effects of treatment on bone abnormalities.
What to expect in a bone scan?
What you can expect. A bone scan is a nuclear imaging procedure. In nuclear imaging, tiny amounts of radioactive materials (tracers) are injected into a vein and taken up in varying amounts at different sites in the body. Areas of the body where cells and tissues are repairing themselves most actively take up the largest amounts of tracer.
What is the reason for bone scan?
Bone scans are useful in a wide range of diseases. A common reason to obtain a bone scan is in the evaluation of pain, in which a bone scan can help determine whether the source of the pain is from bone pathology or from the soft tissues.
What does a bone scan show?
A bone scan is done to show problems with bone metabolism — the process of building and recycling bone tissue. Some activity is normal, but too much or too little bone remodeling is a sign of disease or injury.
How long is a bone scan?
A whole body bone scan takes around 3-4 hours, which includes two separate visits. In the first visit you will be given an injection of a radioactive isotope into a vein in your arm.
