Bone metabolism refers to the process in which bones break down and rebuild themselves. The test may be uncomfortable if you are having joint or bone pain. Areas of the body where cells and tissues are repairing themselves most actively take up the largest amounts of tracer. Plus, we give quick fixes for when…. 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.
After the injection you can leave the department for a couple of hours. Mann Dr.
But you may find lying still uncomfortable. The tracers in the radioactive substance used in a bone scan produce very little radiation exposure.
Exposure to radiation during a bone scan can slightly increase your risk of developing cancer in the future. Discuss any recent illnesses, medical conditions, allergies and medications you're taking, including vitamins and herbal supplements. How is the procedure performed? You might have a test scan immediately after the injection. Nuclear medicine imaging procedures are noninvasive and — with the exception of intravenous injections — usually painless medical tests that help physicians diagnose and evaluate medical conditions.
Talk to your doctor or radiographer if this worries you. McGraw-Hill; 2014.
The special camera and imaging techniques used in nuclear medicine include the gamma camera and single-photon emission-computed tomography SPECT. Nevertheless, you should inform the nuclear medicine personnel of any allergies you may have or other problems that may have occurred during a previous nuclear medicine exam.
A nuclear medicine technologist will perform the skeletal scintigraphy procedure. It takes a few hours, usually two to four hours, for the radiotracer to circulate through your body and bind to your bones so that the pictures can be taken.
The resolution of structures of the body with nuclear medicine may not be as high as with other imaging techniques, such as CT or MRI.
You may be asked to wear a gown. Call your health care team right away if you have pain, redness, or swelling around the injection site on your arm.
But your doctor may ask you to drink lots of water for the next 1 to 2 days. You will be asked to wear a gown during the exam. Elsayes KM, et al. Brandon, David C.
