A CT scan, also known as a computerized tomogram or CAT scan, is a noninvasive type of X-ray that helps doctors diagnose medical conditions that may not be visible on other types of imaging technology.

Using a CT scan allows radiologists the ability to see more than what a regular X-raycan provide. Wellcare radiologists review and interpret CT scans to diagnose a variety of illnesses, including abdominal, cardiac, musculoskeletal, neurological, spine-related, and thoracic conditions. Wellcare offers patients the most advanced CT scanner technology available, providing images of exceptional quality, while using the lowest possible radiation dose to keep you safe.

Why Doctors Order a CT Scan

CT scans enable doctors to see cross-sectional images of your internal organs. CT scans can potentially help your doctor see the cause of your symptoms, diagnose certain diseases, and evaluate treatment response. Critical information can be provided to your doctor, often more quickly and economically compared with other tests.
Compared to MRI, CT provides a better evaluation of certain elements such as air, blood, and calcifications. This means that air-containing structures such as the lungs are better studied using CT.

Preparing for a CT Scan

You may be asked not to eat or drink anything for up to three hours before your CT scan, especially if a contrast material is going to be used in your exam. You should inform your doctor of any medications that you are taking and if you have any allergies. You can take your medications before the CT scan.
Talk with your doctor before the CT scan for any specific instructions. Also, please inform your doctor of any recent illnesses or other medical conditions, such as a history of heart disease, asthma, diabetes, kidney disease, or thyroid.
Some abdominal CT scans require the administration of water or oral contrast material to allow the radiologist to evaluate your bowel and also to separate the bowel from other important organs and tissues.

During a CT Scan

Our CT technologist takes you into the CT scanner room and positions you on the table, which moves into the doughnut-shaped portion of the scanner. At this point, the CT technologist exits the room. You and the technologist are able to speak with each other through an intercom system.
The exam length depends on the type of scan that has been ordered for you. Most people are on the scanning table for less than 10 minutes. A technologist communicates with you throughout the exam and lets you know if additional images need to be taken.

After a CT Scan

When your scan is completed, you may resume your regular diet and activities. We recommend that you drink plenty of non-alcoholic, decaffeinated fluids, such as water or juice, to help your body flush out any IV or oral contrast material.
After your CT scan, our radiologists read the images and dictate a report that is sent to your doctor, who contacts you with the results.
