Multislice CT Services

Imaging Services at Sibley Hospital offers the latest in computed tomography (CT) imaging, including 64-slice CT technology, which is capable of performing the latest in diagnostic imaging. Traditional examinations, such as a CT of the abdomen, can be performed in a single 10-second breath hold with current technology. The 64-slice technology also allows the department to perform more complex examinations, including the following.

CT Scan

Coronary CT Angiography

Coronary CT angiography (CCTA) acquires images of the heart in a very short period of time. This allows the radiologist to see the blood vessels supplying blood to the heart by the coronary arteries. An IV is started, and contrast is injected to directly visualize these vessels. Medications (beta blockers) are given to regulate the heart rate. CCTA tests take about two hours.

Virtual Colonoscopy

Virtual colonoscopy in a noninvasive way to visualize the inside of the colon. A CT scan is performed with the patient lying on their stomach and then on their back. Special software is utilized to allow the radiologist to look at the inside of the colon. Anesthesia is not necessary for this exam, and it usually takes only 30 minutes. Patient preparation is required.

Low-Dose Lung Screening

Lung cancer is the leading cause of cancer deaths in the United States. Most patients do not exhibit symptoms of lung cancer until the tumor is too large to be effectively treated. Low-dose CT scans are taken of the lungs to detect the presence of lung nodules or cancers while they are very small and treatments can be more effective.

Calcium Scoring (Heart Screening)

The presence of calcium deposits in the coronary arteries can be a predictor of more severe disease in these arteries. This is a 15-minute screening exam used to measure the amount of calcium in the coronary arteries.

All of these tests require a physician to receive the report and to provide you with follow-up care. Insurance restrictions may apply.
