The advantage of a MUGA scan over an echocardiogram or an angiogram is its accuracy. An echocardiogram measures the shortening fraction of the ventricle and is limited by the user's ability. Furthermore, an angiogram is invasive and, often, more expensive. A MUGA scan provides a more accurate representation of cardiac ejection fraction. [1]
For men over 64 with prostate cancer limited to the pelvis, using fewer, larger doses of radiation (hypofractionation) results in similar overall survival rates. [28] The risk of dying from prostate cancer or having acute bladder side effects may be similar to that of longer radiation treatment. [ 28 ]
Radionuclide therapy can be used to treat conditions such as hyperthyroidism, thyroid cancer, skin cancer and blood disorders. In nuclear medicine therapy, the radiation treatment dose is administered internally (e.g. intravenous or oral routes) or externally direct above the area to treat in form of a compound (e.g. in case of skin cancer).
Cardiac ventriculography involves injecting contrast media into the heart's ventricle(s) to measure the volume of blood pumped. Cardiac ventriculography can be performed with a radionuclide in radionuclide ventriculography or with an iodine-based contrast in cardiac chamber catheterization.
The U.S. Preventive Services Task Force recommends that adults ages 45 and older should be screened for colon cancer, and that men over 55 discuss whether to get screened for prostate cancer with ...
It is first necessary to derive a digital number that is proportional to the amplitude of the analog pulse. This is performed in an Analog-to-Digital Converter (ADC) which is a key part of the MCA. Several linear and fast ADCs have been developed over the years (e.g., Wilkinson). [17] One of the first MCAs was developed by Fred Goulding in the ...
Areas covered by the Radiation Exposure Compensation Program. The United States Radiation Exposure Compensation Act (RECA) is a federal statute implemented in 1990, set to expire in July 2024, providing for the monetary compensation of people, including atomic veterans, who contracted cancer and a number of other specified diseases as a direct result of their exposure to atmospheric nuclear ...
Intravenous digital subtraction angiography (IV-DSA) is a form of angiography which was first developed in the late 1970s.. IV-DSA is a computer technique that compares an X-ray image of a region of the body before and after radiopaque iodine based dye has been injected intravenously into the body.
