64‐Slice CT scans

What is CT?

Also known as a “CAT scan,” Computer Tomography is an x-ray technique that generates images of the inside of the body. Instead of a single X-ray image, a CT scan produces a series of “slices” that allow a highly detailed and precise view for the radiologist. AROC performs many types of CT scans, including imaging the abdomen/pelvis, head/neck, extremities, spine, chest and various preventative screenings especially of the heart

CT imaging is used to clearly show soft tissue, like the brain, as well as dense tissue, like bone. The information gathered during a CT scan is processed by a computer and interpreted by a radiologist to diagnose or rule out disease.

The Toshiba Aquilion 64-slice CT scanner used at AROC is the most advanced scanner of its kind, capable of producing exceptionally detailed, precise and vivid images. In addition to reducing the amount of time required for testing (some full-body scans can be completed in as few as 10 seconds), this technology enables almost anyone to have a high quality CT scan, including claustrophobic or anxious patients, children and those with difficulty breathing.

Some CT scans require the use of a contrast medium. Given intravenously, the contrast agent highlights certain body parts to enable the radiologist to better see any abnormalities. For example, CT scans of the abdomen and pelvis often require the patient to drink a barium-based liquid to outline the intestines for better viewing.

CT Scans for Heart Health

Because of their ability to see both soft and dense tissue, images from our advanced 64-slice CT scanner offer a variety of ways to monitor your heart health. For example, we can perform the non-invasive Coronary CT Angiography and detect, quantify and characterize the plaque in your coronary arteries, even plaque at risk of rupture that wouldn't be detected by EKG or stress profusion. The CTA is a less invasive, less expensive alternative to cardiac catheterization. 

Another great tool for you to use to monitor your heart health is the Coronary Calcium Score, also known as the Heart Scan. It's the most accurate model for measuring a patient's risk of coronary artery disease, designed to identify it at the pre-clinical, or asymptomatic, stage. Using our advanced 64-slice CT scanner and special software, we can effectively quantify the amount of calcified plaque in your arteries and then recommend options to halt--or even reverse--the progression of the disease. 

What should I expect during the exam?

A CT scan will typically take 10-30 minutes, depending on the area of the body being imaged. In some cases, you may be required to drink an oral contrast, or receive an IV contrast, depending on the type of test your doctor has ordered.

How do I prepare for a CT?

Unless a contrast agent is needed, no other special preparation is required. However, please inform your radiologist or technologist in advance of your scan if you:

• Are pregnant
• Have had a previous adverse reaction to iodine contrast injection
• Have renal disease
• Are claustrophobic
• Are over 65
• Have asthma and use an inhaler two or more times per day
• Are diabetic and taking glucaphage

A report of your examination results will be provided to your doctor, usually within 24 hours of your test.
