What To Expect
|
You will be asked to remove all jewelry, hairpins, eyeglasses,
hearing aids and dentures. For abdominal exams, your doctor should
direct how long before the scan you should refrain from eating or
drinking.
Let your physician know if you have had allergic reactions to a
contrast medium, iodine or shellfish, or if you have asthma. Also
inform the radiologic team if you have diabetes or take medication.
If contrast medium is used, it will be given either intravenously,
or by mouth to coat the gastrointestinal tract. Most people tolerate
the contrast medium without any problems and merely feel flushed for a
moment.
Though the images are acquired within a few seconds, the entire
exam takes about 15 to 30 minutes; longer if contrast medium is used. |
