About Computed Tomography (CT)
Computed tomography (CT) uses X-rays and computers to create highly detailed cross-sectional images of a patient's internal organs, bones, and blood vessels. This technology produces multiple images of a single focal area, providing radiologists with several vantage points as they work with other specialists and care teams to find answers for each patient. CT is a reliable tool for detecting and accurately diagnosing a variety of conditions and abnormalities.
CT technology is commonly used in the following imaging studies:
Calcium scoring utilizes CT to evaluate the amount of calcified (hardened) plaque in a person's arteries and determine the likelihood of a heart attack. Physicians compare the findings to other patients of the same sex and similar age, ultimately quantifying the patient's risk for a cardiac event.
A coronary angiogram uses CT to provide visual images of the arteries that supply blood to the heart, creating three-dimensional images that reveal the presence both hard and soft plaque. This information can help determine a patient's risk for heart attack and/or help care teams manage a patient's coronary artery disease (CAD).
CT colonography (also known as virtual colonoscopy) generates detailed images of the colon, rectum, and surrounding organs. This test can sometimes be used instead of a colonoscopy to help detect cancers, polyps, inflammation, or diverticula.
Lung Cancer Screening
Low-dose CT lung cancer screenings produce multiple high-quality images that can facilitate the detection of many lung diseases and conditions. This test is most often utilized for patients with a high risk of developing lung cancer but no signs or symptoms of disease.
