Diatrizoate, also known as amidotrizoate, Gastrografin, is a contrast agent used during X-ray imaging. [1] This includes visualizing veins, the urinary system, spleen, and joints, as well as computer tomography (CT scan). [1] It is given by mouth, injection into a vein, injection into the bladder, through a nasogastric tube, or rectally. [2] [3]
European guidelines classify a pre-existing decreased kidney function to be a risk factor of contrast-induced nephropathy in the following cases: [5]. Estimated glomerular filtration rate (eGFR) < 45 ml/min/1.73 m 2 of body surface area before intra-arterial administration with first-pass renal exposure (not passing lungs or peripheral circulation before kidneys), or in the intensive care unit

This is a list of mnemonics used in medicine and medical science, categorized and alphabetized. A mnemonic is any technique that assists the human memory with information retention or retrieval by making abstract or impersonal information more accessible and meaningful, and therefore easier to remember; many of them are acronyms or initialisms which reduce a lengthy set of terms to a single ...
Confusion is often reported as a possible clinical symptom. [33] The FDA has asked doctors to limit the use of gadolinium contrast agents to examinations where necessary information is obtained only through its use. [35] Intrathecal injections of doses higher than 1 mmol are associated with severe neurological complications and can lead to death.
Hypersensitivity to iodinated contrast medium or a history of iodinated contrast dye anaphylaxis is not a contraindication of ERCP, though it should be discussed with your health provider, and you should tell them you are allergic to iodine, as an alternative contrast iodine-free material ("dye") is then injected gently into the ducts ...
However, there are no absolute contraindications to iodinated contrast, so the benefits needs to be weighted against the risks. [14] As with CT scans in general, the radiation dose can potentially increase the risk of radiation-induced cancer. The injection of iodinated contrast agents may sometimes lead to its extravasation. [15]
The loss of contrast sensitivity can be quickly and easily measured by a contrast sensitivity test like Pelli Robson performed either at home or by an eye specialist. [citation needed] When viewing an Amsler grid, some straight lines appear wavy and some patches appear blank [67] When viewing a Snellen chart, at least 2 lines decline [citation ...
