    However, for patients at high risk of contrast-induced nephropathy, it is possible to reduce the required amount of contrast using dual energy CT. With such a protocol, only 7–10 g of iodine (20–30 cc of 370 mg/ml iodine solution) may be needed. [10]

    Contrasted CT scans of the chest are usually used to confirm diagnosis of for lung cancer and abscesses, as well as to assess lymph node status at the hila and the mediastinum. CT pulmonary angiogram , which uses time-matched ("phased") protocols to assess the lung perfusion and the patency of great arteries and veins , particularly to look for ...

    Volume rendered CT scan of abdominal and pelvic blood vessels. CT angiography is a contrast CT where images are taken with a certain delay after injection of radiocontrast material. The contrast material is radiodense causing it to light up brightly within the blood vessels of interest. In order for the CT scanner to be able to scan the correct ...

    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.

    CT scanning can perform a virtual colonoscopy with greater accuracy and less discomfort for the patient than a traditional colonoscopy. [143] [144] Virtual colonography is far more accurate than a barium enema for detection of tumors and uses a lower radiation dose. [145] CT is a moderate-to-high radiation diagnostic technique.

  9. Iodinated contrast - Wikipedia

    en.wikipedia.org/wiki/Iodinated_contrast

    Iodinated contrast is a form of water-soluble, intravenous radiocontrast agent containing iodine, which enhances the visibility of vascular structures and organs during radiographic procedures. Some pathologies, such as cancer , have particularly improved visibility with iodinated contrast.
