Caution: Cardiac Imaging in Progress

Facebook X LinkedIn Email
Unless a patient has worrisome risk factors or symptoms that are suggestive of heart disease, the American Heart Association (AHA) is advising against cardiac imaging tests that use radiation, according to its councils on Clinical Cardiology and Cardiovascular Radiology and Intervention. Risks from the ionizing radiation levels used in cardiac CT and nuclear medicine scans, although low, are not fully understood, and any unnecessary or repeated exposure could be damaging in the long run. These findings by an AHA advisory committee led by Dr. Thomas Gerber were published in the Feb. 3, 2009,...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
