Nuclear Medicine Scans Nuclear medicine scans use small amounts of radioactive dye (tracer) to highlight areas of concern, such as cancer cells or infection. Pictures can than be taken of these areas. There are many types of nuclear medicine scans, including: A special dye called a radioactive isotope, or tracer, is given through an IV. This tracer contains a small amount of radiation, about the same amount as an x-ray. The dye travels through the body and gathers in the area of the body being examined.

Nuclear Medicine - Hepatobiliary Nuclear medicine imaging procedures are noninvasive and, with the exception of intravenous injections, are usually painless medical tests that help physicians diagnose and evaluate medical conditions. These imaging scans use radioactive materials called radiopharmaceuticals or radiotracers. Depending on the type of nuclear medicine exam, the radiotracer is either injected into the body, swallowed or inhaled as a gas and eventually accumulates in the organ or area of the body being examined.

MRI Scan Your body contains millions of hydrogen atoms. When you are in an MRI scanner: 1  A strong magnetic field aligns particles called protons which are within the hydrogen atoms. 2  All the protons line up in parallel to the magnetic field, like tiny magnets. ( 3 Normally the millions of protons all lie in random directions.).

How to Prepare for an MRI A: Depending on the type of MRI scanner and the type of scan your doctor ordered, the MRI technologist may wrap a special belt (actually an antenna) around the region of your body that is to be scanned. If you are having a head scan, your head will rest in a special fixture.ere are some examples: If you are going to have a scan of the lower spine (lumbar spine) or the abdomen area, don't wear clothing or under-clothing that has metal on it in that area. For example, a body suit that has snaps in the crotch, or pants with fasteners or a zipper will cause a problem.

- The contrast used in MRI is different than the CT dyes, and the likelihood of a reaction is even more rare. If the doctor and/or radiologist decides that a contrast scan is necessary, patients must be sure to mention any allergic history (especially to previous dye injections). They also should ask if the dye is absolutely necessary and if so, should request a newer, milder dye.

Nuclear Medicine Procedures Nuclear medicine procedures are used in diagnosing and treating certain illnesses. These procedures use radioactive materials called radiopharmaceuticals. Examples of diseases treated with nuclear medicine procedures are hyperthyroidism, thyroid cancer, lymphomas, and bone pain from some types of cancer. The amount of radioactive materials used in diagnosing illnesses depends on the needs of the person and range from a small amount to a large amount.

Gallbladder Scan A kidney scan is a specialized radiology procedure used to assess the function and structure of the kidneys, as well as the perfusion (blood flow) to the kidney tissue. A kidney scan is a type of nuclear radiology procedure.This means that a tiny amount of a radioactive substance is used during the procedure to assist in the examination of the kidneys. The radioactive substance, called a radionuclide (radiopharmaceutical or radioactive tracer), is absorbed by normal kidney tissue.he gamma radiation is detected by a scanner, which processes the information into a picture of the kidneys. By measuring the behavior of the radionuclide in the body during a nuclear scan, the doctor can assess and diagnose various conditions, such as tumors, abscesses, hematomas, organ enlargement, or cysts.

Cut cost on MRI with largest network of MRI Scan in Delhi MRI stands for magnetic resonance imaging; it basically uses powerful magnets and radio waves to create detailed images of the interior of your body. It can be done with or without contrast. Contrast is a type of dye that is injected intravenously either right before, or during the procedure. Certain abnormalities, such as tumors, will absorb the dye and show up very clearly on the MRI with contrast. Your doctor will determine whether you need an MRI with contrast or without, and may order both tests. An MRI scan is different than a regular x-ray or a CT scan, which both use ionizing radiation to create images. MRI scans generally produce clearer images with much more detail than an x-ray or CT 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:
