There are certain health and functional questions that demand deep, highly detailed investigation. Not long ago, many of these inquiries required exploratory surgery, but thanks to sophisticated imaging advances like computed tomography (otherwise known as a “cat scan”), many medical mysteries can be discovered, diagnosed and even treated, quickly, safely and with greater accuracy without invasive or risky procedures.
What is Computed Tomography (CT)?
CT is a highly sophisticated x-ray exam that produces 3D-quality cross-sectional images of internal organs and systems. The donut-shaped imager scans the area of interest with 360-degree thoroughness, capturing dozens of images of organs, soft tissues, bones and blood vessels with remarkable speed for the lowest possible radiation exposure. The numerous images are assembled into a composite image for painstaking inspection by your radiologist and referring clinician. Apart from an injectable contrast agent that may be used to enhance details, CT is non-invasive, completely painless and takes only minutes to perform. You simply lie still while the scanner captures images. Because RAO uses advanced helictical CT, you can expect a quick and comfortable experience, with minimal interruption of your day.
What Conditions Warrant a CT Scan?
Because CT is so thorough and accurate, it can be used to diagnose a wide array of internal injuries, diseases and dysfunctions. Here we describe some of CT’s most common applications, but the complete roster is more extensive.
CT’s exceptional detailing is capable of capturing injury and disease nearly anywhere in the body. CT can detect problems in the joints and bones, from complex fracture to tumors to arthritic conditions. CT can discover even tiny abnormalities in the organs and tissues, including masses, internal bleeding, clots and infection. CT can be used to guide biopsies, plan surgery and deliver radiation treatment.
CT angiography (CTA) is used to study the heart and blood vessels for damage, disease, obstruction and other problems. CT is also used for a screening exam called cardiac scoring, which reveals the presence and severity of calcified plaque in the coronary arteries, so treatment can be used to help prevent a heart attack before it strikes.
CT enterography (CTE) is used to diagnose and evaluate gastrointestinal problems affecting the small bowel such as inflammation, tumors, obstructions, fistulas and diseases like Crohn’s. CT enterography utilizes an oral contrast agent to capture fine details.
Parathyroid 4D-CT is a four-dimensional imaging exam used to examine parathyroid glands for even the tiniest tumors, lesions and abnormalities. Parathyroid 4D-CT can be beneficial to many patients who were previously considered ineligible for additional surgical treatment, providing for some a renewed chance for a cure.
Lung Cancer Screening
One of CT’s most revolutionary uses is in the early discovery of lung cancer among high-risk patients. Low Dose Computed Tomography, or LDCT, is a specialized chest scan that can reveal the earliest stages of lung cancer before it produces symptoms and has a chance to spread. Regular LDCT screening can catch lung cancer very early on, when it is highly treatable. While anyone can get lung cancer, it is by far most common among heavy smokers age 50 and older. People who quit smoking within the past 15 years are still considered at elevated risk. If you wonder if LDCT might be right for you, have an honest talk with your clinician.
Why Choose RAO for CT?
When your doctor prescribes a diagnostic CT scan or an LDCT screening, you have a choice of providers to perform your procedure. Why choose RAO? Locally-owned and operated since 1973, RAO consistently leads the field in today’s most advanced medical imaging technologies and procedures. RAO features helical CT for optimal image quality, superior detection, reduced radiation exposure and faster exam times compared to standard CT. We also offer 128-slice CT for extremely high detail when needed for a rapid diagnosis or to stage treatment.
Our Board-certified, subspecializing radiologists read all test results personally, and interact directly with your clinician. Our doctors are the exclusive imaging providers for AdventHealth Ocala, Ocala Regional Medical Center, West Marion Community Hospital and Bayfront Health Seven Rivers in Citrus County.
Finally, and perhaps most important, RAO is the imaging provider friends and neighbors throughout the region know and trust. RAO’s radiologists, technologists and talented support staff not only serve our community, they are part of it.
Should you need a CT scan, another diagnostic exam or an interventional treatment, we hope you’ll come see us. RAO is here to provide advanced, accurate and considerate care, and assist your clinician with focused and effective resolutions.
