These standards do not supersede the judgment of the individual nuclear medicine technologist and other healthcare professionals serving the patient in light of all of the facts of the individual case. In this example, the gamma camera detector measures 50 15cm and is read out by 30 PM tubes 5cm in diameter. An image is formed from a histogram of the number of events at each possible X-Y location. This instrument, the Anger scintillation camera,1 or gamma camera, has been substantially refined and improved since that time. Nuclear Medicine Scans for Cancer Nuclear medicine scans ( also known as nuclear imaging, radionuclide imaging, and nuclear scans) can help doctors find tumors and see how much the cancer has spread in the body (called the cancer's stage ). Thyroid uptake study: to evaluate functions of the thyroid gland using sodium iodide 131I. Brachytherapy is commonly used as an effective treatment for cervical, prostate, breast, and skin cancer. It should have a short half-life, again to keep the radiation dose as low as possible. An array of PM tubes is coupled optically to the back face of the crystal with a silicone-based adhesive or grease. Single Photon Emission Computed Tomography or SPECT and Positron Emission Tomography or PET scans However, a malfunctioning gamma camera may result in errors in diagnosis or an non-interpretive study so that the patient gets no benefit from the radiation exposure arising from the administered radiopharmaceutical.

Four radionuclides account for the large majority of clinical procedures. Some are particles or aggregates of molecules labelled with a radionuclide. A sodium iodide [NaI(Tl)] scintillation detector (see, In the late 1950s, Anger replaced the film-screen combination with a single, large-area, NaI(Tl) crystal and a photomultiplier (PM) tube assembly to greatly increase the detection efficiency of his camera concept. "description": "Nuclear medicine procedures may be: diagnostic studies, which are tests of body function. A nuclear medicine scan uses small amounts of radiation to create pictures of tissues, bones, and organs inside the body. This is illustrated in one dimension in Figure 13-4. This branch of radiology is often used to help diagnose and treat abnormalities very early in the progression of a disease, such as thyroid cancer. Re-focus with SNMMI's technologist-focused publications and enhance your nuclear medicine knowledge and comprehension.

This approach also permits improved handling of pulse pile-up at high counting rates, as described in Section B.2. This would enable the position of an event to be determined by taking a weighted average or centroid of the PM tube signals using the simple relationships shown in. Take the Pharmacy College Admission Test (PCAT). Common uses of radioactive drugs for imaging tests include scans of your: Healthcare providers use radioactive drugs for certain treatments to target a harmful organ or tissue. It's injected intravenously, then circulates in the body, sticks to the tumor cells, delivers radiation directly and causes them to die.
