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. It can also assess how well your heart pumps blood to your body.
The test can detect problems with blood flow in the heart tissue and can diagnose ischemic heart disease. A nuclear heart scan is an imaging test that uses special cameras and a radioactive substance called a tracer to create pictures of your heart. Nuclear medicine is a type of medical imaging that uses small amounts of radioactive material called tracers to help find and or.
What is nuclear medicine. In normal tissue the tracer is evenly distributed and the area appears uniform on the scan. Areas with less active cells show up as cold spots or darker areas.
The radiotracer travels through the area being examined and gives off energy in the form of gamma rays which are detected by a special camera and a computer to create images of the inside of. Nuclear medicine uses small amounts of radioactive materials called radiotracers that are typically injected into the bloodstream inhaled or swallowed. Martin on july 05 2020 are nuclear medicine scans for cancer safe.
Molecular imaging and the brain reviewed by laura j. Society of nuclear medicine and molecular imaging. Nuclear medicine scans provide the most useful diagnostic or treatment information for many diseases.
Nuclear medicine examinations provide unique information including details on the function and anatomy of body structures that is often unattainable using other imaging procedures. A radioactive material radiopharmaceutical is injected into a vein attaches to the bones and is detected by a special camera gamma camera that takes images or pictures that show how the bones are working. A nuclear medicine bone scan also shows whether there has been any improvement or deterioration in a bone abnormality after treatment.
These scans use liquid substances called radionuclide s also called tracers or radiopharmaceuticals that release low levels of radiation.
Nuclear medicine scan images. Nuclear medicine is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease nuclear medicine imaging in a sense is radiology done inside out or endoradiology because it records radiation emitting from within the body rather than radiation that is generated by external sources like x rays in addition nuclear medicine scans differ. A nuclear medicine thyroid scan is necessary to diagnose the specific disorder. Unlike other forms of medical imaging such as mri or pet scans nuclear medicine scans have the advantage of showing metabolic function in real time. For a nuclear medicine thyroid scan the scan measures the rate at which the thyroid absorbs iodine.
Nuclear scans make pictures based on the body s chemistry like metabolism rather than on physical shapes and forms as is the case with other imaging tests.
