The CT topogram is the equivalent of chest X-ray rather than using an X-ray machine, it uses a CT scanner. It produces a similar picture using X-rays generated from the CT scanner.
Typically, a chest topogram is used if someone is suffering with a respiratory condition and the consultant wants to check the lung tissue for evidence of disease.
How should I prepare for this test?
There is no special preparation for this scan. However, it is recommended that you do not smoke for at least four hours before it takes place. Whilst there are no injections it is advisable to wear comfortable and loose-fitting clothing.
What to expect during a Chest Topogram?
On the day you will be asked to remove your clothing on the top half of your body, and you will be given a gown to wear. You will be asked to lie on the scanner. You’ll be alone in the scan room during the scan, but our friendly experts will always be able to speak to you and hear you. The scan should take no more than 15-20 minutes and you will be given the results straight away.
