The diagnostic work-up should include a thorough physical examination, including the pelvis, breasts, lymph nodes, skin and should limit unnecessary exposure to ionizing radiation. Fine needle aspiration, core needle or open excisional biopsies are safe to perform. Chest X-ray and mammography with abdominal shielding and ultrasonic examinations are the cornerstone of a basic staging, supplement...

Single photon emission tomography SPECT has been used in nuclear medicine since the early 1960’s when Kuhl and Edwards developed a rectilinear scanning system for use in neuronuclear medicine. Tomography is now used extensi vely for diagnosis by ultrasound, x-ray CT scanning and magnetic resonance imaging. The improvement in quality of the images is due to the enhanced contrast produced by the ...

This paper reviews the preparation and application of radioactive microspheres for medical purposes. It first discusses the properties of relevant radioisotopes and then explores the diagnostic uses of gammaemitter labeled microspheres, such as blood flow measurement and imaging of the liver and other organs. The therapeutic uses of alphaand beta-emitting microspheres, such as radioembolization...

Background: Technetium-99m radioisotope is the backbone of any nuclear medicine institute. This radioisotope is acquired by the elution of Molybdenum-99/Technetium-99m generator which emits 141 keV gamma ray and having 6.04 hour half-life. Occasionally the contents of Molybdenum-99 may mix up with elute, which may affect image quality and patients may receive higher doses than recommended. This...

From the Newsline editor: Across the globe, the practice of nuclear medicine depends on the sometimes difficult-toachieve confluence of skilled practitioners, specialized equipment, and readily available supplies of short-lived radionuclides. As a result of variations in each of these crucial elements, the practice of nuclear medicine can be quite different from one region of the world to anoth...
