Computed Tomography (CT)
CT combines X-rays and computers to generate detailed cross-sectional images of the body. These images allow radiologists to non-invasively detect and diagnose a variety of abnormalities. With advances in scanner technology and computing capabilities, the uses for CT and quality of the images continues to improve, making it a reliable and invaluable tool for diagnostic imaging.
Versatility in imaging.
CT scans can be used to visualize nearly all parts of the body. They can aid in the detection of cancer, cardiovascular disease, musculoskeletal disorders, trauma to internal organs and gastrointestinal abnormalities. When your doctor recommends a CT scan, Eastern Radiologists is the place to go. Our Greenville location and outpatient office in Kinston offer state-of-the-art technology as well as convenience. Each scan is performed by a highly trained technologist and interpreted by an experienced, board-certified radiologist. All of our facilities are accredited by the American College of Radiology, a designation only awarded after rigorous review of factors like safety, scan quality and attention to minimizing radiation dose. Remember that when you need a CT scan, the choice is yours. Ask your doctor for a referral to Eastern Radiologists.
Frequently Asked Questions
Are IVs or “shots” involved?
Some scans require oral, IV and/or rectal contrast to better visualize specific parts of the body. The technologist will ask several questions related to medical conditions that could affect the use of contrast material. It’s important to let the technologist know if you’ve ever had an allergic reaction to contrast.
What should I expect?
A CT technologist will guide you through the procedure and can talk to you via intercom throughout the study. You will lie on a padded table, which moves through a doughnut-shaped scanner. It’s critical to lie still and follow the technologist’s instructions along the way. You may be asked to hold your breath for short periods of time. The scan itself usually lasts less than one minute, but the total time in the scanner room is typically 10 – 20 minutes.
Does insurance cover my procedure?
Most major insurance carriers will cover most CT exams. Some require authorization before the study, so please check with your insurer at least one day prior to your appointment. ERI participates in most healthcare plans and will file your insurance claims directly; however, payment may be required at the time of service for some patients. Please bring any insurance cards to your appointment. Patients are responsible for services not covered by insurance. Please call our office at 252.752.5000 with additional insurance questions.
Prepare for your appointment.
An accurate medical history is required when your appointment is scheduled, including age, history of allergic reaction to CT contrast material, and prior medical conditions including renal disease, asthma, diabetes and high blood pressure. A blood test may be required in some cases to evaluate your renal function.
On the day of your appointment, please stick to clear liquids (water, tea, coffee (no cream), soft drinks, Jello (no fruit) apple juice, cranberry juice, ice popsicles) for six hours prior to the exam. Please leave all jewelry at home. Additional instructions specific to certain studies are as follows:
Head, Neck, Chest, Spine & Extremities
If intravenous (IV) contrast is ordered, do not eat or drink six hours prior to exam.
Abdomen & Pelvis
If IV contrast is ordered, do not eat or drink six hours prior to exam. Most cases are performed with oral and IV contrast. Oral prep can be picked up at our Doctors Park location, or in some cases your physician will provide it. Please follow the instructions with the oral prep. If you are unable to pick up your prep ahead of time, you can come in early the day of your appointment and drink it here.
CT Angiogram (CTA)
Do not eat six hours prior to the exam. The CTA will be performed with IV contrast, and in some cases, oral contrast may also be given.
