Computed Tomography (CT)

Computed tomography (CT) scans, also called computerized axial tomography (CAT) scans, are a medical imaging method that uses X-rays to generate detailed cross-sectional images of the body. These image "slices" are used to detect broken bones, cancers, blood clots, signs of heart disease and internal bleeding and to guide biopsies.

How You Benefit

CT scanning is fast, painless and usually noninvasive. Compared to regular X-rays, a CT scan provides extremely detailed high-resolution images, and it captures organs, bones, soft tissue and blood vessels all at the same time. This highly detailed and precise imagery helps doctors diagnose your condition more accurately.

Advanced Technology for Diagnosis & Treatment

We offer leading-edge 64-slice CT scanning and a large-opening scanner with tumor localization technology. Used with our radiation planning system, the scans can simulate treatment in 3D–allowing for the highest degree of accuracy in radiotherapy.

We also have the technology to combine CT scanning with positron emission tomography (PET) for an even higher-level accuracy and definition in disease diagnosis. Combined PET/CT scans are particularly helpful in pinpointing cancer, providing critical information for differentiating benign and malignant masses, evaluating the effectiveness of radiation and chemotherapy and detecting tumor recurrence earlier. With this combined technology, you can be assured your doctors are basing your care decisions on the most accurate information available.

What to Expect

A CT scan usually takes only 10-15 minutes. Depending on the type of scan, an intravenous (IV) needle may be placed in your hand or arm and used to inject a contrast dye during the test or the contrast may be given orally as a drink.
