If you’ve been told that you need to have a CT scan in order to provide a more accurate diagnosis of a possible heart condition, you might be concerned as to what the procedure actually involves. Whilst some people are familiar with the process, it’s possible that you might not be, and the prospect of having it may feel a little daunting as a result.
Here’s a brief explanation as to what a CT scan actually is and what to expect during the procedure.
CT Scan: What Exactly Is It?
A CT scan helps specialists to gain really useful insight as to what’s happening inside your body. It uses X-ray imaging to create a three-dimensional cross-section of a particular area, and can be used to diagnose or monitor a wide number of health conditions.
In most cases, the procedure is carried out by a trained radiographer. In certain circumstances, a CT scan may be used to help assist with another treatment; for example, if you’re undergoing a biopsy, a CT scan is really useful in helping your surgeon to direct the needle to the correct position.
The machine itself is ring-shaped, and inside the ring is the X-ray. This creates a beam of X-rays that capture the image of the interior of your body. You’ll lie flat on the table, the tube will rotate gradually around you, and the images will be gathered. These are then transmitted to a computer, which creates the final cohesive images for the doctor to refer to.
What to Expect During the Procedure
CT scans are painless and completely non-invasive. They are conducted as an outpatient procedure and you won’t be expected to stay overnight. Before having the scan, it’s likely that your radiographer will talk to you and this is a good time to ask any questions that you might have.
It’s also important to let your radiographer know if you suffer from any conditions, such as asthma, kidney problems, allergies or diabetes. If you’re concerned about being enclosed in a narrow, dark space, let your radiographer know. It’s likely that they’ll be used to dealing with people who suffer with claustrophobia, and they’ll know how to put you at ease.
You’ll be asked to remove any obstructive clothing and put on a gown. You’ll also be asked to remove items such as jewelry, dentures, glasses or hearing aids. Dye may be applied to your body, in order to help the visibility of the tissue. Alternatively, it may be injected into a vein.
The scan itself takes approximately 15-20 minutes. At various points, your radiographer will ask you to hold your breath or not to swallow. This is in order to get the best image possible. It’s also incredibly important to remain as still as you can.
