What to Expect During a CT of
the Brain
Although the exact procedure you will follow
may be different than the information provided here, this is a general
description of the exam.
A CT technologist will position you on
the exam table and place your head in a specially designed holder that
is fitted with velcro straps. This helps you hold your head still during
the exam and should not cause any discomfort.
The exam table then moves into position
and your exam begins. During the scan, you will hear a "whirring" sound
as the x-ray tube rotates around you. You will also feel the exam table
move in small increments as the pictures are taken.
Usually two sets of pictures are done.
After the first set, the CT technologist may need to inject an iodine contrast
agent into a vein on the arm or hand. If this is necessary, the procedure
will be explained to you in more detail.
Typically, the CT examination takes
10 to 20 minutes to perform.
