Introduction
Iohexol is a medical contrast agent widely used in myelography, urography, angiography, and contrast-enhanced CT scans. Iohexol oral contrast imaging is a method that involves administering an oral contrast agent followed by visualization of internal organs using imaging equipment. It is recommended that iohexol oral contrast examinations be performed at正规 hospitals under the supervision of qualified physicians.
Iohexol is a medical contrast agent widely used in myelography, urography, angiography, and contrast-enhanced CT scans. Taking chest imaging as an example, the specific procedure is as follows:
1. Before the examination, patients should take oral laxatives and fast (no food or water) for six hours.
2. After orally administering the iohexol contrast agent, wait for half an hour.
3. The patient lies supine on the examination table, with the head placed in a head holder to begin the scan. During the examination, a contrast monitor is used to observe whether there are any pathological changes or other abnormalities in the thoracic cavity.
4. At the end of the examination, the patient sits up and leaves the examination room.
High-atomic-number medications such as bismuth and calcium should be discontinued three days prior to the procedure to avoid interference with the examination results. Oral iohexol contrast examinations are recommended to be performed at正规 hospitals under the supervision of qualified physicians.
