CAT Scan Q&A
What is a CAT scan?
During a CAT scan, the device takes a series of X-ray images from different angles around your body. Then a computer processes the information, digitally stacking different angles together to produce highly detailed, three-dimensional images.
When might I need a CAT scan?
A CAT scan produces clear images of your bones, organs, and soft tissues, including your muscles, lungs, heart, blood vessels, stomach, kidneys, and intestines.
This type of imaging reveals the precise details needed to diagnose many health conditions. These are just a few examples:
- Internal injuries
- Fractures
- Head injuries
- Chronic sinusitis
- Musculoskeletal disorders
- Gastrointestinal disease
- Pneumonia or interstitial lung disease
- Colon polyps and tumors
- Brain tumors or brain injury
- Primary and metastatic cancers
- Arterial disease and aneurysms
You may also need a CAT scan to evaluate the effectiveness of certain treatments.
What is a CAT scan with contrast?
Contrast refers to a dye or contrast material that highlights specific structures in your body. Your contrast drug may be administered orally or intravenously, depending on the body area being scanned.
When you get your contrast agent through an IV, you may feel a warm flushing sensation or have a metallic taste in your mouth. These sensations are normal and go away quickly.
Some contrast drugs contain iodine. If you’re scheduled for this type of procedure, the team at Excel Diagnostics & Nuclear Oncology Center asks if you’re allergic to iodine or ever had a reaction to X-ray dye.
How do I prepare for a CAT scan?
The team gives you specific preparation instructions, such as food and drink limitations, based on the type of CAT you are having. Otherwise, you don’t need to do anything special to prepare for a CAT scan.
What should I expect during a CAT scan?
The CAT scanner is a large, donut-shaped machine with a round tunnel that goes through the center of the device. The machine is open on both ends, so you won’t feel like you’re enclosed.
You lie on the table, and your CAT technician makes sure you’re correctly positioned, then your CAT scan begins. During your scan, it’s essential to lie still, and your technician may ask you to hold your breath for a short time. The table may move slowly through the machine, depending on the type of scan.
Though your CAT technologist is in an adjoining room, they see you, and you can communicate throughout the scan.
