Computed tomography, sometimes called a CT scan, is a modern medical imaging system in which an x-ray transmitter rotates around the patient. A CT scan can photograph the internal parts of the organs and divide overlapping structures precisely, creating cross-sectional scans of all areas of the body. A CT scan is a helpful diagnostic tool that helps recognize a number of different conditions or illnesses. It can be used to find irregularities within your body or assist during surgery. If you have digestive health issues and require a CT scan in Phoenix, AZ, our team can help. Please call your local Arizona Digestive Health location to request a consultation with one of our experienced providers.

The need for a CT scan varies from person to person. Some of the main reasons a CT scan is done are:


  • To identify internal bleeding or internal damage
  • To oversee disease and ailments including heart disease, lung nodules, liver masses, and cancer
  • To support operations, radiation therapy, and biopsies
  • To track down bone and muscle maladies like bone fractures and tumors
  • To locate an infection, a tumor, or a thrombus

A radiologist, certified by the American Board of Radiology, oversees the CT scan. The radiologist may be assisted by a radiology technician and perhaps a radiology nurse. You might be asked not to consume food or liquid for a set number of hours prior to your scan with our Phoenix, AZ team. A contrast agent, sometimes called “dye,” could be administered to outline vascular systems or strengthen organ images. If a contrast agent is used, it will be administered into a vein, usually in your arm. Some or all of the agent may be administered by a syringe, or all of it may run steadily into your vascular system through an intravenous (IV) drip. A history of contrast (such as iodine) sensitivity should be reported to our team before the CT scan. You will be asked to lie on a platform that moves into an empty ring in the center of the CT scanning machine. X-rays move through the area of interest on your body and are detected by computerized sensors. You will be given breathing instructions, and then the bed will run gradually through the CT scanner. The full scan will be finished within minutes. You will not experience any pain during the scan. Information from these sensors are then digitally processed and displayed as a picture on the monitor. Film copies of these images may be made for further examination.

EAST VALLEY GASTRO- Dr Panossian: The most caring physician I have seen in years. Not that the others have been bad, he is just several notches above. He is very upbeat, great bedside manner with exceptional communication. Took his time and seemed to really care to find the cause of my belly pain- even suggesting possibilities outside of his scope of practice. He's definitely one of the good ones. I'd recommend him to anyone!
