Skeletal Scintigraphy (Bone Scan) Bone Scan. Guide. A bone scan is a test that can find damage to the bones, find cancer that has spread to the bones, and watch problems such as infection and trauma to the bones. A bone scan can often find a problem days to months earlier than a regular X-ray test.During a bone scan, a radioactive substance called a tracer is injected into a vein in your arm. The tracer travels through your bloodstream and into your bones. Then a special camera takes pictures of the tracer in your bones.Areas that absorb little or no amount of tracer appear as dark or cold spots.hy It Is Done. A bone scan is done to: 1  Find bone cancer or determine whether cancer from another area, such as the breast, lung, kidney, thyroid gland, or prostate gland, has spread (metastasized) to the bone. 2  Help diagnose the cause or location of unexplained bone pain, such as ongoing low back pain.

- A lung scan is a specialized radiology procedure used to examine the lungs to identify certain conditions. A lung scan may also be used to follow the progress of treatment of certain conditions. A lung scan is a type of nuclear medicine procedure. This means that a tiny amount of a radioactive substance is used during the procedure to assist in the examination of the lungs. There are 2 types of lung scans: ventilation scans and perfusion scans.

- A bone scan is an imaging test that safely uses a very small amount of radioactive dye to help diagnose problems with your bones. This test reveals problems with bone metabolism. The normal process of bone metabolism includes how bones are broken down and how they rebuild themselves.

What is a nuclear heart scan? A nuclear heart scan is a test that provides important information about the health of your heart. For this test, a safe, radioactive substance called a tracer is injected into your bloodstream through a vein.The tracer travels to your heart and releases energy. Special cameras outside of your body detect the energy and use it to create pictures of your heart. Nuclear heart scans are used for three main purposes: When a nuclear heart scan is done for this purpose, it's called myocardial perfusion scanning. 2  To look for damaged heart muscle. 3  Damage might be the result of a previous heart attack, injury, infection, or medicine.

- Why nuclear medicine imaging is done. A nuclear medicine scan may be done to: 1  check the structure and function of tissues or organs, such as the brain, thyroid, lungs, heart, liver, spleen, kidney and bone. 2  detect disease in organs or bones. 3  find tumours, especially in the bones and thyroid.

Thyroid Nuclear Medicine Scan A thyroid nuclear medicine scan is a diagnostic procedure to evaluate the thyroid gland, which is located in the front of the neck and controls the body's metabolism.A radioactive substance that concentrates in the thyroid is taken orally or injected into a vein (intravenously), or both.his indicates that this area of the thyroid gland is underactive. A variety of conditions, including cysts, nonfunctioning benign growths, localized inflammation, or cancer may produce a cold spot. A thyroid nuclear medicine scan is rarely sufficient to establish a clear diagnosis.

FDA warns of rare but serious risk of heart attack and death with cardiac nuclear stress test drugs Lexiscan (regadenoson) and Adenoscan (adenosine) Lexiscan and Adenoscan cause blood to flow preferentially to the healthier, unblocked or unobstructed arteries, which can reduce blood flow in the obstructed artery. In some cases, this reduced blood flow can lead to a heart attack, which can be fatal..

Spine Tests: Bone Scan A bone scan is a useful diagnostic tool that spine surgeons sometimes use to detect areas of unusual activity in the bones. Bone scans are also known as nuclear imaging, because they capture pictures of the body using low-levels of radioactive elements. Why We Use Bone Scans. Bone scans provide surgeons with a detailed assessment of areas of abnormal bone activity. This test can be important for diagnosing spinal problems such as:

Bone scan for bone cancer What is a bone scan? A bone scan is an imaging test that can detect cancerous cells, evaluate fractures in the bones, and monitor other bone conditions, such as infections and arthritis.During a bone scan, a small dose of radioactive material is injected into a vein, where it travels through the bloodstream. bone scan can detect cancer that has metastasized to the bone from a different primary site, such as the breast, prostate or lungs.

Nuclear Scans Nuclear scans use radioactive substances to see structures and functions inside your body. They use a special camera that detects radioactivity. Before the test, you receive a small amount of radioactive material. You may get it as an injection. Sometimes you swallow it or inhale it.

- The three phase bone scan detects different types of pathology in the bone. The first phase is also known as the nuclear angiogram or the flow phase. During this phase, serial scans are taken during the first 2 to 5 seconds after injection of the Technetium-99m-MDP. This phase typically shows perfusion to a lesion.

- A multigated acquisition scan (also called equilibrium radionuclide angiogram or blood pool scan) is a noninvasive diagnostic test used to evaluate the pumping function of the ventricles (lower chambers of the heart).uring the test, a small amount of radioactive tracer is injected into a vein. A special camera, called a gamma camera, detects the radiation released by the tracer to produce computer-generated movie images of the beating heart. The MUGA scan is a highly accurate test used to determine the heart’s pumping function.
