CT Scan

Service Overview

What is a CT?

Computed Tomography (CT), sometimes called “CAT scanning,” uses special x-ray equipment to obtain image data from different angles around the body, and then uses computer processing of the information to show a cross-section of body tissues and organs.

Low Dose Scans:

Our GE Revolution™ Maxima

The AI-based Auto Positioning* Xtream camera uses real-time depth sensing technology to generate a 3D model of the patient’s body. Using a deep learning algorithm to align with the isocenter, this equipment is designed to maximize clinical performance for intelligent superior imaging! And our GE Revolution™ Maxima allows us to lower patient radiating dose to our patients by 82%

What to Expect:

The technologist or technologist’s aide has you change into clothes appropriate for your particular exam. That individual asks you questions about medical history pertinent to the exam being done that day. You will be asked to lie down and depending on the type of exam you may be given a pillow for your head and under your legs.

The CT scanner is shaped like a ring or doughnut and the part of your body being looked at passes back and forth through the ring. The CT scanner is programmed to give breathing instructions in 24 different languages.

Some exams require the use of IV contrast. The contrast highlights blood vessels and gives greater definition to the organs being evaluated. IV contrast is injected into your bloodstream and produces a warm flush sensation that last roughly 30 seconds.

Abdominal scans require you to also drink oral contrast followed by water. The oral contrast distends the stomach and intestines allowing our radiologist a better look at inside those organs.

While inside CT scanner, the CT technologist is able to hear you and talk to you over a microphone/speaker.

Our CT technologists are here to help. Feel free to ask any question or concern you may have.

Lung Cancer Screening Program in conjunction with Community Medical Centers

Smoking continues to be the leading cause of lung cancer deaths in men and women.  Screening and early detection for lung cancer can drastically improve lung cancer survival rates by finding and treating the disease at an early stage.  Smokers and past smokers, who are within the ages of 55-77 years old, may be eligible for the preventative screening program.

The Lung Cancer Screening Program works directly with the Community Cancer Institute and the Lung Nodule Program to provide holistic care to each patient.

Once enrolled in this program, a low-dose chest CT scan is performed at Advanced Medical Imaging annually to ensure your lungs are monitored on a regular basis.  This continual care is the key to cancer prevention and keeping you healthy.  A lung screening nurse coordinator will be in direct contact with you and your physician to make sure the screening process is easy and stress-free.

Contact Community Medical Centers’ Lung Cancer Screening Program  If you are smokers or past smoker, who are within the ages of 55-77 years old, you may be eligible for this preventative screening program.
