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.
Relatively common side effects include vomiting, diarrhea, and skin redness. [4] 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]
Of the CT scans, six to eleven percent are done in children, [168] an increase of seven to eightfold from 1980. [167] Similar increases have been seen in Europe and Asia. [167] In Calgary, Canada, 12.1% of people who present to the emergency with an urgent complaint received a CT scan, most commonly either of the head or of the abdomen.
An upper gastrointestinal series, also called a barium swallow, barium study, or barium meal, is a series of radiographs used to examine the gastrointestinal tract for abnormalities. A contrast medium , usually a radiocontrast agent such as barium sulfate mixed with water, is ingested or instilled into the gastrointestinal tract, and X-rays are ...
Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4. It is a white crystalline solid that is odorless and insoluble in water. It occurs in nature as the mineral barite, which is the main commercial source of barium and materials prepared from it. Its opaque white appearance and its high density are exploited ...
What’s more, once a person has tried two different antidepressants, stayed with each one for long enough to feel the effects, and doesn’t get relief, their depression is considered treatment ...
A CT myelography scan can identify the site of a cerebrospinal fluid leakage. Once identified, the leak can often be repaired by an epidural blood patch , an injection of the patient's own blood at the site of the leak, a fibrin glue injection, or surgery.
