    Abscess scan - radioactive

    Radioactive abscess scan looks abscesses in the body using a radioactive material. An occurs when pus collects due to an infection.

    Bone scan

    A radiotracer is injected into a peripheral vein.  As the radiotracer decays, gamma radiation is emitted and is detected by a Gamma camera.  When the tracer has collected in the target organ the area is scanned.  Radionuclide scans can detect abnormalities such as fractures, bone infections, arthritis, rickets, and tumors that have spread, among other diseases.

    A bone scan is an imaging test that shows areas of increased or decreased bone turnover ().

    Gallbladder radionuclide scan

    The gallbladder radionuclide scan is performed by injecting a tracer (radioactive chemical) into the bloodstream.  A gamma camera is used to perform the scan.  The camera will detect the gamma rays being emitted from the tracer, and the image of where the tracer is found in the organs is transmitted to a computer.  This test is very good for detecting acute infection (cholecystitis) or blockage of a bile duct. It is also helpful in determining whether there is rejection of a transplanted liver.

    Gallbladder radionuclide scan is a test that uses radioactive material to check gallbladder function. It is also used to look for or bile duct obstruction.

    Gallium scan

    The gallium scan is a type of nuclear scan involving radioactive gallium which helps determine whether a patient has inflammation in the lungs. Gallium is injected in a vein and a series of x-rays are taken to identify where the gallium has accumulated in the lungs. This test is most often performed when there is evidence of inflammation in the lungs (sarcoidosis).

    A gallium scan is a test to look for swelling (inflammation), infection, or cancer in the body. It uses a radioactive material called gallium and is a type of exam. A related test is .

    Liver scan

    After a radioisotope has been injected into a vein, a series of pictures are taken of the liver by a scanner.  The liver scan is probably the best way to study the liver without surgery. It is particularly valuable because it can provide information about liver function. It is also used to help confirm other test results.

    A liver scan uses a radioactive material to check how well the liver or spleen is working.

    MIBG scintiscan

    This image shows enlargement of the thyroid gland and extension down behind the breastbone (retrosternal space). The image, called a scintiscan, was generated using a radioactive isotope.

    An MIBG scintiscan is a type of imaging test. It uses a radioactive substance (called a tracer) and a special scanner to find or confirm the presence of and neuroblastoma. These are types of tumors that affect the nervous tissue.

    Nuclear stress test

    A radiotracer is injected into a peripheral vein.  As the radiotracer decays, gamma radiation is emitted and is detected by a Gamma camera.  When the tracer has collected in the target organ the area is scanned.  Radionuclide scans can detect abnormalities such as fractures, bone infections, arthritis, rickets, and tumors that have spread, among other diseases.

    Thallium stress test is a nuclear imaging method that shows how well blood flows into the heart muscle, both at rest and during activity.

    Nuclear ventriculography

    During the MUGA test, a radioactive isotope is injected into the vein. Radioactive isotopes attach to red blood cells and pass through the heart in the circulation. The isotopes can be traced through the heart using special cameras or scanners. The test is often given at rest, then repeated with exercise, or after administering certain medications. The test is performed to detect certain heart conditions.

    Nuclear ventriculography is a test that uses radioactive materials called tracers to show the heart chambers. The procedure is . The instruments do not directly touch the heart.

    Radioactive iodine uptake

    Radioactive iodine uptake test is a type of nuclear test performed to evaluate thyroid function.  The patient ingests radioactive iodine (I-123 or I-131) capsules or liquid.  After a time (usually 6 and 24-hours later), a gamma probe is placed over the thyroid gland to measure the amount of radioactivity in the thyroid gland.  The values are then compared.

    Radioactive iodine uptake (RAIU) is a test of thyroid function. It measures how much radioactive iodine is taken up by the thyroid gland in a certain time period. A similar test is the . The two tests are commonly performed together.

    Radionuclide cisternogram

    Cerebral spinal fluid (CSF) is a clear fluid that circulates in the space surrounding the spinal cord and brain. CSF protects the brain and spinal cord from injury by acting like a liquid cushion.  CSF is usually obtained through a lumbar puncture (spinal tap).  During the procedure, a needle is inserted usually between the 3rd and 4th lumbar vertebrae and the CSF fluid is collected for testing

    A radionuclide cisternogram is a nuclear scan test. It is used to diagnose problems with the flow of spinal fluid.

    Radionuclide cystogram

    Cystography is a detailed study of the bladder, which uses a dye and X-rays.  A catheter is inserted into the bladder in which the dye flows.  When the bladder is full, the catheter is removed and the X-rays are taken. X-rays are also taken when the bladder is empty.  The test is performed to check for the integrity of the bladder, determine the cause of infections and check for tumors or stones.

    A radionuclide cystogram is a special imaging test called a that checks how well your bladder and urinary tract work.

    RBC nuclear scan

    An RBC nuclear scan uses small amounts of radioactive material to mark (tag) red blood cells (RBCs). Your body is then scanned to see the cells and track how they move through the body.
