Also called nuclear medicine scan. A test of the structure, blood flow, and function of the kidneys. The doctor injects a mildly radioactive solution into an arm vein and uses X-rays to monitor its progress through the kidneys.
in liver disease, it determines how much, if any, bile is flowing through the liver.
A technique in which radioactive dye is injected into a vein, so that images of the body can be recorded to detect the cancerous tissue. The brain, bone, and liver are common sites scanned.
test using small amounts of radioactive material to compare left and right lung functions (blood flow and gas exchange)
A procedure in which a weak radioactive substance called a "radioactive tracer" is injected into the bloodstream. A device that resembles an x-ray machine then moves over the area being tested and takes pictures.
For this test, a radioactive substance is injected during exercise. Then a special image is taken of the heart, to see how well blood is flowing through the heart.
A diagnostic procedure in which a weak radioactive substance is injected into the blood stream. The body then absorbs the substance. A machine, like a giant Geiger counter, moves over the area being tested and takes pictures.
is an imaging procedure where a low-dose radioactive tracer is either ingested or injected before images are taken.
A test that measures blood flow to the heart muscle to assess performance or damage.
A variety of Xray studies incorporating radioisotopes that are injected into the bloodstream, to reveal the functioning of the heart. These tests can accurately measure the efficiency of the heart pump and show areas where the muscle has been injured. While nuclear scans often fit into a thoroughdiagnosticc workup, they cannot take the place of cardiac catheterizationn because only catheterizationn can reveal blockages in the coronary arteries.
A procedure in which a weak radioactive material called a radioactive tracer is injected in the blood. The material is taken up by the body, and a machine moves over the area being tested to collect the emission of the radioactive tracer.
