You must remain completely still while the scanner takes pictures of your chest. The machine makes a buzzing or clicking sound, and you may feel some vibration from it during the scan, but it’s not painful.

The entire process usually takes about 15 to 20 minutes for the chest CT Scan to be done. A CT scan generates significantly more detailed images than a standard X-ray. You don’t have to take any special precautions after the procedure unless told by your doctor.

How Do I Prepare for a CT Scan

After learning about the most prevalent applications of this technique, you may be asking how to prepare for a chest CT scan. These are the things you need to keep in mind before your appointment:


Imagine getting dressed up for a big function only to have to change as soon as you get there. That could happen in some cases. Wear comfy, easy-to-remove garments to avoid wardrobe mishaps.

Plus, you never know when you might have to part with all your metal accessories – even your trusty glasses. So next time you’re getting ready, think twice about that chunky necklace or statement belt. Who knows, it might save you some hassle in the end.


CT scans require a small amount of radiation. However, it’s only a precaution to ensure everything looks nice. Moreover, your body absorbs little radiation, which won’t hurt it.

However, if you’re pregnant or suspect, you could be. It’s crucial to inform your doctor before your scan. Better safe than sorry, right? Ask questions and voice concerns about your health and safety.


Before any scans, diabetics should make sure their blood sugar is steady. Otherwise, the procedure may have negative effects. Your doctor will recommend you eat a light breakfast or lunch three hours earlier than the scan time.

This will help regulate your glucose levels and give you the best possible results. Drink plenty of water before and after your scan, diabetic or not. Staying hydrated is key to a successful procedure.


Better safe than sorry is a common health-related saying. When it comes to allergies, this is completely accurate. If you suspect an allergic reaction or response, see a doctor immediately.

Your doctor needs to know about any potential allergens before prescribing medications or treatments. Discover your allergies and manage your symptoms with your doctor.


Many people take medication every day, but imaging studies like chest CTs need you to follow your doctor’s instructions. While you can generally continue taking your regular medications leading up to the day of the procedure, certain drugs can interfere with the imaging process or image results.

Before the scan, your doctor may advise you to cease using blood thinners and other drugs. And if you’re a coffee or cocktail lover, you may need to switch it up beforehand too.
