CT Scan

What is a CT scan?

CT (computer-aided tomography) scans combine X-rays with computer technology to create detailed images of the inside of your body. 

Instead of creating one image like a traditional X-ray, a CT scan takes multiple images as the machine rotates around your body. 

While each X-ray shows a “slice” of the inside of your body, the CT computer can stack those slices to create a 3D representation of nearly any part of your body.

Sun Radiology has 64 slice/128-channel CT equipment that creates remarkably detailed images, including brain, lungs, abdomen, pelvis, spine, cardiac, angiogram, and neuroimaging. 

While a traditional CT scan may have only produced 4- or 16-slice images, Sun Radiology invests in the best emerging digital imaging technology to provide you with a rapid, accurate diagnosis. 

Why would I need a CT scan?

CT scans provide detailed images of almost every part of your body and have a multitude of uses. 

For example, your doctor may order a CT scan for headaches, back pain, abdominal, or pelvic pain to identify masses or tumours in your abdomen, study your cardiovascular system for chest pain, or examine your head and brain for signs of tumors and blood clots. 

Your doctor may request a CT scan to study your lungs if they suspect you have a tumor, pulmonary embolism, or conditions like emphysema or pneumonia. 

You may also need a CT scan to diagnose complex bone fractures or severely arthritic or eroded joints. CT scans can also reveal bone tumors.

What happens during a CT scan?

You usually change into a hospital gown and remove all jewelry, eyeglasses, and hearing aids for a CT scan. You may need to fast for several hours before your scan if you need a contrast dye injection.

During your CT scan, you lie on a table and stay as still as possible as it moves through the CT machine. The machine rotates around you, taking multiple digital X-rays. You may need to hold your breath for a few seconds to ensure the device creates clear images. 

Your CT technician operates the machine from a neighboring room. They can see you through a glass panel and can talk to you throughout your scan. 

While CT scans are safe, you should let your radiologist know if you’re pregnant, breastfeeding, or have thyroid or kidney disease.
