Short Summary
Main recommendation: Prepare for a CT scan by following your clinic's instructions, which often means not eating for a couple of hours beforehand, and remove all clothing and jewelry except underwear before the scan so metal does not interfere with image quality. The video explains that a CT scan is quick and painless, usually under 30 minutes, and the machine never touches you.
Key Points
- A CT (computed tomography) scan is an imaging study that takes a look inside your body, and the machine never touches you.
- The whole process usually takes less than 30 minutes.
- Fasting for a couple of hours before the appointment helps the doctors see everything they need as clearly as possible.
- You will fill out a questionnaire in the waiting area after check-in.
- During the scan you lie on a table that slides through the donut-shaped scanner, and staff watch from the next room while you can speak through a microphone at any time.
Details Worth Noting
- Concrete instructions:
- Before the appointment, follow the preparation instructions clinic staff give you when booking, which usually means not eating for a couple of hours beforehand.
- On arrival, check in at the front desk, complete the questionnaire in the waiting area, and wait to be called.
- Change into a gown after removing all clothing and jewelry except underwear, and store your belongings in the lockers provided.
- If an IV is needed, a nurse will place it before you enter the scan room.
- Lie still on the sliding table, using any safety straps, pillows, or a head cradle staff provide, and hold your breath if the technologist asks, to avoid blurred images.
- If you have contrast material, drink plenty of fluids afterward to help your kidneys flush it from your body, and follow any special instructions given.
- A parent may stay with you during the scan if you are nervous, but they must wear a lead apron.
- You may hear buzzing, clicking, and whirring noises as the detectors rotate around you.
- After the exam you can usually return to normal activities, but you may be asked to wait briefly before leaving to make sure you feel fine.
- The technologist sends the results to your doctor, who is the person who reviews them.
Bottom Line
A CT scan is a quick, painless imaging test, and the main things you control are fasting if instructed, removing metal, and staying still during the scan.
