If your doctor has ordered a CT (Computed Tomography) scan, it is natural to feel a bit nervous or unsure about what to expect. However, the procedure is generally quick and straightforward, and the more you know about what to expect, the more comfortable you are likely to feel. Here is a comprehensive guide for patients on what to expect during a CT scan:
Before the scan:
- You may be asked to remove any metal objects, such as jewelry or hairpins, as these can interfere with the scan.
- Depending on the area of your body being scanned, you may be asked to change into a hospital gown.
- If you are receiving a contrast dye, you may be asked to fast for a few hours before the scan to ensure accurate results.
During the scan:
- You will lie on a table that slides into a large, circular scanner. The scanner may be open or closed, depending on the model used.
- The technician will give you instructions on how to lie still and may use a strap or foam blocks to help you remain in the correct position.
- The scanner will emit a series of X-rays, which will produce detailed images of the inside of your body. You may hear whirring or clicking noises as the scanner moves around you.
- If you are receiving a contrast dye, it will be injected into your vein through a small needle, either before or during the scan. You may experience a warm sensation or metallic taste in your mouth as the dye is injected.
- The scan itself typically takes only a few minutes, although you may be asked to hold your breath briefly during certain parts of the scan.
After the scan:
- You will be able to resume your normal activities immediately following the scan.
- If you received contrast dye, you may be asked to drink plenty of fluids to help flush it out of your system.
- Your doctor will review the results of the scan and discuss them with you at a later appointment.
In summary, a CT scan is a non-invasive imaging procedure that typically takes only a few minutes to complete. Although it may feel intimidating at first, understanding what to expect can help you feel more comfortable and confident during the process.
