Brain Scan Preparation
There are minimal preparations for a CT scan. We will
inform you of any steps you may have to take when you
book your appointment.
What to Expect
Most CT examinations are similar and include the following
steps:
You should wear comfortable, loose fitting clothing
for your CT exam. You must also remove any articles
of clothing or jewelry that might degrade the CT images,
such as belts, earrings, bras, glasses, dentures, hairpins,
etc. Zippers and snaps common in many clothes can also
cause image degradation. In some cases, you may be asked
to wear a patient gown.
Once you are for many types of CT exams, for example
CT of the chest or abdomen, you are asked to hold your
breath and remain perfectly still for less than 30 seconds
while the technologist takes the image. At any time
during the CT examination, you may communicate with
the technologist using an intercom. The technologist
controls the CT examination from a workstation console
in the control room next to the room with the CT scanner.
The technologist watches over you during the exam to
ensure your comfort and monitors the progress of the
image acquisition.
You may hear the CT scanner rotating during the study.
Depending upon the type of study being performed, the
whirring noise may be very quiet or more noticeable.
The table will move very slowly during the CT data acquisition.
Once the CT examination is complete, the technologist
will ask you to get dressed and wait while the CT images
are reviewed on the monitor.
