CT
What is a CT scan?
Computed Tomography (CT) is an x-ray examination performed with a computerised
x-ray scanning machine. The CT scan looks at the body in cross section. To
produce images, a narrow beam of x-rays is rotated around the part of your body
to be examined. The x-ray beam is monitored and recorded by an array of
sensitive detectors which channel the signals to a large computer within the
scanner. The computer then generates a visible image of the cross section of the
body region being examined. The resulting pictures are recorded on a laser
camera and printed on film, and sometimes onto a CD.
Preparation
You will need to make an appointment for this examination. Depending on the
type of CT examination requires, you may be asked to fast or to drink oral
contrast prior to the study, this may require you to arrive earlier for your
appointment.
We may ask you to remove your hairclips, earrings, pins, chains
or other items of jewellery before the examination, as these can sometimes
interfere with the scan. We may also need you to change into a gown, depending
on the type of examination being performed. You may be asked to sign a consent
form prior to the procedure.
