Dual Source Scanner - Computer Tomography (CT) Scan

Why is the doctor performing this procedure?
Setting new standards in cardiac diagnosis, the dual source computed tomography (CT) scanner can image patients with high or irregular heart rates, or even arrhythmia, without beta-blocker medications that have been previously needed to slow a patient's heart. The system also enables physicians to better identify and characterize plaque, an early indicator of heart disease.

"With the new scanner, physicians can get detailed, razor-sharp images that can identify life-threatening blockages, blood clots and other heart problems - in their earliest, most treatable stages," says Meriter Medical Imaging Acting Director Mary Alice Johns.

What is the procedure?
CT scans use x-rays and a computer to visualize the body. The scans produce two-dimensional images of anatomy, like a cross section. The new dual source, ultra fast CT scanner is the first to use two x-ray sources and two detectors at the same time.

Where is the procedure performed?
The procedure is performed in Meriter Medical Imaging.

How long does the procedure take?
The new technology means a faster exam that is noninvasive, safer and very efficient. The actual scan takes less than 15 seconds, or, in most cases, a single breath hold. Following the procedure, patients are free to continue with their normal daily activities.
