CLINICAL MEDICINE

Detailed explanation-1: -For a CT scan with contrast, your technologist will often use an iodine-based material or a material containing barium sulfate, a type of powder. If you’re having an MRI scan with contrast, your technologist will use a contrast dye containing the element gadolinium.

Detailed explanation-2: -Iodine-based contrast materials injected into a vein (intravenously) are used to enhance x-ray (including fluoroscopic images) and CT images.

Detailed explanation-3: -Gadolinium contrast media (sometimes called a MRI contrast media, agents or ‘dyes’) are chemical substances used in magnetic resonance imaging (MRI) scans. When injected into the body, gadolinium contrast medium enhances and improves the quality of the MRI images (or pictures).

Detailed explanation-4: -Both gadolinium contrast (used for MRI) and iodinated contrast (used for CT, angiography and other procedures that involve X-rays) leave the body in the urine, which is made by your kidneys.
