Difference Between CT Scan With Contrast and Without Contrast If your doctor suggested a CT scan, you might have seen or heard two terms that can sound confusing at first: CT scan with contrast and CT scan without contrast. Both types use advanced X-ray technology to form images of the inside of the body in great detail, but the use of a special contrast dye during the exam is the principal difference between the two. This variation may seem like technical jargon to the patient, but it serves a significant role in identifying and diagnosing certain presentations. Knowing the two types of CT scans helps you generally prepare yourself for what to expect and understand why your doctor might think one type of CT scan is better than the other for your examination.
