What to Expect During the Exam
Computerized Axial Tomography (CT)
Prior to the CT exam the technologist will explain the procedure. Depending on the type of exam your physician ordered, you might be given oral contrast material one hour before your scan. The radiology nurse may start an intravenous line needed to administer the contrast material.
The average CT exam takes between 15 and 30 minutes. The technologist will be in constant contact with you throughout the exam.
