  1. Millard Neisler:

    In medical science, contrast dye plays an essential role in solving human health riddles. Using different types of tests like CT scans, MRIs and angiograms, doctors and ancillary healthcare workers can begin to unravel mysteries of the human body. Although not the only piece of the puzzle, these scans provide a significant advantage when it comes to knowledge and detection of many ailments.

  2. Pansy Plumadore:

    Contrast materials, also called contrast agents or contrast media, are used to improve pictures of the inside of the body produced by x-rays , computed tomography CT , magnetic resonance MR imaging, and ultrasound. Often, contrast materials allow the radiologist to distinguish normal from abnormal conditions. Contrast materials are not dyes that permanently discolor internal organs.

  3. Deidre Dierking:

    Intravenous IV dye dye given through the vein —also known as radiocontrast media RCM —is used widely in the United States for various radiological studies, such as angiograms, X-rays, magnetic resonance imaging MRI , and computed tomography CT scans. Adverse reactions to RCM are fairly common, though allergies are rarer.

  4. Jc Jerome:

    When a MRI is performed on a patient, contrast dyes may be administered. The method of entry of the contrast dye will vary based on the part of the body that is imaged.
