The significance of increased periprosthetic uptake however is less certain. A normal study ie one in which periprosthetic uptake is indistinguishable from surrounding nonarticular bone rules against a prosthetic abnormality figure 1. Bone scintigraphy is widely available easily performed and extremely sensitive.
A bone scan can also be used to determine whether cancer has spread to the bones from another area of the. A bone scan is a good way to view and document abnormal metabolic activity in the bones. Whereas the typical radiographic features of a fracture such as mineralisation loss and callus formation may take several days to weeks to evolve bone scans become abnormal within a day or two after the event as sufficient osteogenic response to the injury will have developed for detection by this method.
When might a bone scan be positive when the x ray is negative. Bone scintigraphy is a highly sensitive diagnostic nuclear medicine imaging technique that uses a radiotracer to evaluate the distribution of active bone formation in the skeleton related to malignant and benign diseases as well as physiological processes. The radionuclide bone scan is the cornerstone of skeletal nuclear medicine imaging.
Results can show abnormal bone cells and advanced arthritis as well as help determine the cause of bone pain. Bone scans are also helpful in looking for determining whether cancer has metastasized or spread to the bones. A bone scan can often help physicians diagnose bone infections or osteomyelitis bone tumors and fractures.
A bone scan looks at the bones to see if there are any abnormalities such as a fracture tumour or infection. A bone scan is a nuclear medicine imaging test that uses bone seeking radioactive materials or tracers radiopharmaceuticals and a computer to create an image of the skeleton bones. A bone scan is a nuclear imaging procedure.
What you can expect. Tell your doctor if you re pregnant or think you might be pregnant or if you re nursing. Bone scans aren t usually performed on pregnant women or nursing mothers because of concerns about radiation exposure to the baby.
X trustworthy source mayo clinic educational website from one of the world s leading hospitals go to source some activity is normal but too much or too little bone remodeling is a sign of disease or injury.
Nuclear medicine bone scan normal vs abnormal. Bone scans cannot identify some types of cancer. Occasionally an abnormal finding on a bone scan may require additional tests like ct mri blood tests or a biopsy to help distinguish between normal and abnormal bone. Nuclear medicine procedures can be time consuming. A bone scan is done to show problems with bone metabolism the process of building and recycling bone tissue.
