Computed Tomography, abbreviated as CT, is a procedure that uses a computerised, narrow beam of X-rays that are aimed at the body of a patient in a rotating circle. The procedure is generally quite quick but can range in length depending on the type of scan being performed. The rotating X-rays produce cross-sectional image slices (processed by the computer of the scanner), which provide greater detail than traditional X-ray.
What is a CT scan?
When might we use it?
A CT scan is used when greater detail is required for the clinician to diagnose or monitor recovery of an injury. You may need a CT scan if you have a problem with a bone structure or if you have trauma to the spine or brain. CT scans are also used to investigate bone tumours. To make certain parts of the body show up clearer, contrast dye is sometimes used for the scan.
What happens during the procedure
Modern CT machines are exceedingly fast so that the whole chest can be scanned during a single breath-hold. You will need to lie still while scanning takes place and the radiographer will remind you about this. It is important to keep still just as you need to keep still for photographs – any movement during scanning can mean that the images will be blurred and the study may need to be repeated.
I have been told that I might need an injection of a dye. Is this correct?
Yes. Depending on the question(s) being asked, we may need to inject a dye (called ‘contrast’) into one of the veins in your arm. The contrast flows in and highlights blood vessels. This helps the radiologist when interpreting the scan.
The dye is very safe and only very rarely causes problems (e.g. allergic reaction). Most patients notice a warm feeling after the contrast is injected. This is completely normal and will wear-off within a few minutes.
What makes our CT beyond better?
At OneWelbeck, our CT uses “Smart Dose”, intelligent technology that allows us to capture high quality images but with low doses of radiation. This ensures we are making our scans as safe as possible for our patients. Our CT devices use “Spectral Technology”, meaning our lesion/damage detection is second to none. The technology in our devices gives our specialists the best tools possible to ensure your road to recovery.
