The Ultimate Guide to Preparing for a CT Scan of the Abdomen and Pelvis

If your doctor has recommended a CT scan of your abdomen and pelvis, you might be feeling a little unsure about what to expect, especially when it comes to preparation. The good news? It’s a straightforward process, and with a bit of guidance, you will be well-prepared and less anxious.

In this guide, we will walk you through everything you need to know about your CT abdomen and pelvis scan preparation, including what to expect on the day of your imaging.

But first, let’s start with the basics.

What is a CT Scan of the Abdomen and Pelvis?

A CT (Computed Tomography) scan uses X-rays and computer technology to create detailed cross-sectional images of the inside of your body.

When you are going for a CT scan of the abdomen and pelvis, the scan gives doctors a clear look (in great detail) at your blood vessels, bones, soft tissues, and organs in that area like the liver, kidneys, bladder, uterus, and intestines.

This type of CT scan helps diagnose and monitor a wide range of conditions, such as:

Abdominal pain or swelling
Kidney stones
Bowel issues like Crohn’s disease or diverticulitis
Tumours or cysts
Injuries or trauma
Unexplained weight loss
Suspected infections or abscesses

Why Proper CT Scan Abdomen and Pelvis Preparation Matters

Good preparation can make a big difference in how clear and useful your test images are. Without the right prep, your scan might need to be rescheduled, or the images might not show what your doctor needs to see.

That’s why proper CT abdomen pelvis preparation is an essential step in the process. It ensures your scan goes smoothly and gives the most accurate results.

Depending on the reason for your scan, your doctor or our radiology clinic will give you specific instructions. Following these guidelines closely helps ensure your results are accurate, so you won’t need to come back for a second scan.

In general, the preparation you’ll need depends on a few things:

Whether contrast dye is being used (this might also call for a CT abdomen pelvis enhanced preparation [scroll down to know more])
The time of your scan
Your general health (e.g. if you have diabetes or kidney problems)

CT Abdomen and Pelvis Preparation Guidelines

While preparation can vary slightly based on your health and the type of scan being done, here are some things you can expect:

Fasting

If you’re having a scan with contrast (intravenous or oral), you’ll be asked to stop eating for about 4–6 hours before your appointment (this comes under CT abdomen pelvis enhanced preparation).

You can usually still drink water unless told otherwise.

If no contrast is needed, you may be able to eat and drink as usual, but check with your doctor or the imaging center (like CareWell Diagnostix) for specific instructions.

Why fasting? Food in your stomach or bowels can interfere with the scan or reduce the quality of the images. In scans with contrast, fasting also reduces the chance of nausea from the dye.

Medications

Always tell the clinic about any medications you’re taking. You might be asked to skip certain medications for a few hours before your scan, especially if you are diabetic.

Never stop any medications without checking with your doctor first.

Allergies and Medical Conditions

If you’ve had an allergic reaction to iodine or contrast dye in the past, or if you have kidney problems, asthma, or any other allergies, make sure you let the clinic know ahead of time. They might adjust your scan or give you medication beforehand to prevent a reaction.

What to Wear

You’ll probably be asked to wear a hospital gown during the scan. It’s a good idea to wear comfortable, loose-fitting clothes and avoid jewellery or metal objects (like belts or bras with underwire), as they can interfere with the scan.

What Happens During the Scan Day?

On the day of your appointment, arrive early, ideally 15 to 30 minutes before your scheduled time. This gives you time to check in, go over your medical history, and complete any final CT abdomen and pelvis preparation steps like drinking contrast or getting a cannula.

Once you’re ready, the radiographer will help you lie down on the CT scanner bed. The bed slowly moves through a large doughnut-shaped machine. It’s not noisy or enclosed like an MRI, and many people find it much less intimidating. You’ll need to lie still and may be asked to hold your breath for a few seconds while the images are taken.

The scan itself is painless and usually takes 10 to 20 minutes, but the whole visit may take up to an hour depending on preparation time.

You’ll be monitored the whole time, and our team will keep you comfortable throughout.

What Happens After the Scan?

You can usually go back to your normal activities right after your scan. If you had contrast dye, drink plenty of water throughout the day to help flush it out of your system. If anything feels off, don’t hesitate to call the imaging clinic or GP.

The images will be reviewed by a radiologist (a specialist doctor who interprets medical images), and the report will be sent to your referring doctor, usually within a day or two.

Frequently Asked Questions (and Answers)

Will it hurt?

Not at all. The scan itself is completely painless. If you’re having IV contrast, you might feel a brief sting when the cannula goes in, and a warm flush when the dye is injected—but nothing to worry about.

Can I drive after my scan?

Yes! CT scans don’t involve sedation, so you can drive yourself home afterwards.

What if I’m pregnant?

Let your doctor or the radiology clinic know if you are or might be pregnant. CT scans involve radiation, so they’re generally avoided during pregnancy unless absolutely necessary.

Quick Tips to Make Things Easier

Let’s be honest: no one loves medical scans, but here are a few tips to make the process smoother:

Set a reminder for fasting time the night before
Follow your CT abdomen and pelvis preparation instructions carefully. If you’re unsure, call your clinic and ask.
Bring a book or something to keep busy while waiting if your scan involves drinking contrast over time.
Wear comfy clothes and avoid jewellery.
Ask questions. Radiology staff are there to help, and they’ve seen it all. No question is silly.
Don’t stress. CT scans are safe, quick, and routine.
Let the staff know if you’re nervous. They’re there to help.
