What is a non-contrast CT scan?

Answer 1

There are two types of contrast used in CT, oral and IV. The oral contrast is usually a thin barium sulfate suspension and is used to distend and coat the stomach and intestines. IV contrast is usually a nonionic iodinated liquid injected into your arm. This highlights anatomy with blood flow. A noncontrast ct scan usually refers to NOT using the IV contrast, oral may still be used.

Answer 2

Non-contrast means you get your test done without any injections of dye or drinking any oral prep. Most modern CT machines take under 10 minutes for a spine CT and many under 5 minutes. You will lay on the ct scan table. You may need to bring your arms over your head if possible. Some places might have you hold your breath when they acquire the scan. (usually for only 12 seconds or so). This is a very simple exam and causes no pain. (unless it hurts you to just lay down)

Answer 3

A CT scan without contrast means no dye will be used for the exam.
