A CT scan with contrast means the technologist administers a contrast agent that will show up well on the scan because the contrast agent "blocks" or "absorbs" x-rays. Sometimes the difference between body tisssues is so slight that CT scan can't differentiate them well. Since your doctor has asked for a scan of your stomach with contrast, he/she wants to see the fine lining of the stomach ( maybe to look for ulcers or lesions ) . An air contrast upper GI shows that well too. ( you swallow barium with gas pills and your stomach lining shows well on the x-ray. ) CT is slowly replacing upper GI series.

They can do CT without contrast, which takes no prep work. Then, they can put an I.V. in you and do another CT scan. (This contrast is the one that makes them ask you if you are allergic to shellfish. If you are allergic, you must tell them.)

Yes it does. I've had both myself. It highlights in greater detail, certain areas they need more info about. I'm glad we have such a thing!

yup, Can't understand why they didn't do them at the same time though.
