  2. MRI contrast agent - Wikipedia

    en.wikipedia.org/wiki/MRI_contrast_agent

    The spectrum of adverse drug reactions is greater with gadolinium-based contrast agents than with iodinated contrast agents (radiocontrast agents). [ 30 ] Gadolinium has been found to remain in the brain, heart muscle, kidney, liver, and other organs after one or more injections of a linear or macrocyclic gadolinium-based contrast agents, even ...

  3. Contrast agent - Wikipedia

    en.wikipedia.org/wiki/Contrast_agent

    A contrast agent (or contrast medium) is a substance used to increase the contrast of structures or fluids within the body in medical imaging. [1] Contrast agents absorb or alter external electromagnetism or ultrasound , which is different from radiopharmaceuticals , which emit radiation themselves.

    Otherwise a noncontrast helical CT scan with 5 millimeters (0.2 in) sections is the diagnostic method to use to detect kidney stones and confirm the diagnosis of kidney stone disease. [16] [57] [61] [66] [7] Near all stones are detectable on CT scans with the exception of those composed of certain drug residues in the urine, [59] such as from ...

    Intravenous contrast media increases diagnostic capability of enterography MRI. Although it is better tolerated than iodinated contrast media used for CT-scan, the use of gadolinium-based contrast agent should always be preceded by kidney function assessment, in order to reduce the risk of nephrogenic systemic fibrosis , and prophylactic ...

  6. Radiocontrast agent - Wikipedia

    en.wikipedia.org/wiki/Radiocontrast_agent

    Iodinated contrast contains iodine.It is the main type of radiocontrast used for intravenous administration.Iodine has a particular advantage as a contrast agent for radiography because its innermost electron ("k-shell") binding energy is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography.

    Metformin use: Historically, the drug metformin has been required to stop 48 hours pre and post procedure, as it known to cause a reaction with the contrast agent. However, guidelines published by the Royal College of Radiologists suggests this is not as important for patients having <100mls of contrast, who have a normal kidney function .

    Other side effects include itchiness, kidney problems, low blood pressure, and allergic reactions. [1] It is not recommended in people who have an iodine allergy. [1] Diatrizoate is an iodinated ionic radiocontrast agent with high osmolality. [2] Diatrizoate was approved for medical use in the United States in 1954. [4]

  9. Enzyme-activated MR contrast agents - Wikipedia

    en.wikipedia.org/wiki/Enzyme-activated_MR...

    In the sole paper describing in vivo use of enzyme-activated MR contrast agents, the agent was delivered to embryonic cells via a micropipette. However, the authors of the paper acknowledge that this is not a feasible approach for many research projects, [5] and it presents a clear impediment to clinical use. There is active research in using ...
