What to Expect During an MRI, CT, or Ultrasound Procedure

Medical imaging plays a vital role in diagnosing health conditions, and knowing what to expect can help reduce anxiety and make the entire process smoother. At Tranquil and Quest Specialist Hospital (TQSH) in Lekki, Lagos, our imaging team ensures every patient feels safe, informed, and comfortable before, during, and after each procedure.

Whether you’re preparing for an MRI, CT scan, or Ultrasound, this guide explains what happens and how to prepare.

1. What to Expect During an MRI Scan

Before the Scan

  • You’ll be asked about any metal implants, pacemakers, or medical devices.
  • Remove all metallic items such as jewellery, keys, phones, or belts.
  • You may change into a hospital gown for comfort.

During the Scan

  • You will lie on a movable bed that slides into the MRI scanner.
  • The machine uses magnetic fields and radio waves, so you will not feel any pain.
  • It can be noisy; you’ll hear rhythmic tapping sounds, but headphones or earplugs are usually provided.
  • You might hear gentle clanging sounds from the machine.
  • You must stay still to ensure clear images.
  • A radiographer monitors you throughout and can communicate with you at any time.

How Long Does It Take

Most MRI scans take 15–45 minutes, depending on the body area being examined.

After the Scan

  • You can resume normal activities immediately.
  • If contrast dye was used, you may be asked to drink water to help flush it out.

2. What to Expect During a CT Scan

Before the Scan

  • You may be asked to avoid eating for a few hours if contrast material is required.
  • Remove metal objects from the body.
  • Inform the radiographer if you are pregnant or allergic to contrast dye.

During the Scan

  • You will lie on a flat bed that moves slowly through a circular scanner.
  • You might hear gentle whirring sounds from the machine.
  • The scan is quick and painless; you only need to stay still for a few seconds at a time.

How Long Does It Take

A CT scan usually takes 5–10 minutes. With contrast dye, the process may take slightly longer.

After the Scan

  • You can return to regular activities right away.
  • If you received contrast material, drink water to help eliminate it from your system.

3. What to Expect During an Ultrasound Scan

Before the Scan

  • For abdominal ultrasounds, you may need to fast for several hours.
  • For pelvic or pregnancy scans, you may be advised to drink water and not empty your bladder.
  • Wear comfortable clothing for easy access to the area being scanned.

During the Scan

  • You will lie on a couch while a warm gel is applied to your skin.
  • The sonographer moves a handheld device (transducer) over the area.
  • Ultrasound uses sound waves, so the procedure is completely safe and painless.
  • You can see the images on the screen in real time.

How Long Does It Take

Most ultrasounds take 15–30 minutes.

After the Scan

  • You can go back to your normal routine immediately.
  • The gel is wiped off before you leave.

What to Expect During an X-Ray Procedure

X-rays use advanced radiation to capture images of bones, lungs, or internal organs.

Before the Scan

  • You may be asked to remove metal objects from the area being examined.
  • Pregnant women should inform the technologist.

During the Scan

  • You’ll either sit, stand, or lie down depending on the type of X-ray.
  • The technologist positions the X-ray machine and may ask you to hold your breath for a few seconds.
  • The process is quick and painless, usually completed within 5 minutes.

How It Feels

  • You will not feel anything during the X-ray.
  • Some positions may feel slightly uncomfortable but only for a brief moment.
