Comprehensive diagnosis of heart disease with a single CT scan
Date:3/4/2008

CHARLESTON, S.C. (March 4, 2008) In the current issue of the journal Circulation, a research team from the Medical University of South Carolinas (MUSC) Heart & Vascular Center report their initial experience with a novel imaging technique that enables comprehensive diagnosis of heart disease based on a single computerized tomographic (CT) scan.

The team, led by Balazs Ruzsics, MD, PhD; Eric Powers, MD, medical director of MUSC Heart and Vascular Center; and U. Joseph Schoepf, MD, director of CT Research and Development, explored how CT scans can now detect blocked arteries and narrowing of the blood vessels in the heart in addition to poor blood flow in the heart muscle.

The single-scan technique would also provide considerable cost savings, as well as greater convenience and reduced radiation exposure for patients. For their approach, the MUSC physicians used a Dual-Source CT scanner. The MUSC scanner was the first unit worldwide that was enabled to acquire images of the heart with the dual-energy technique. While the CT scan dissects the heart into thin layers, enabling doctors to detect diseased vessels and valves, it could not detect blood flow. The MUSC researchers added two x-ray spectrums, each emitting varying degrees of energy like a series of x-rays, to gain a static image of the coronary arteries and the heart muscle. This dual-energy technique of the CT scan enables mapping the blood distribution within the heart muscle and pinpointing areas with decreased blood supply.

All this is accomplished with a single CT scan within one short breath-hold of approximately 15 seconds or less. In addition to diagnosing the heart, the CT scan also permits doctors to check for other diseases that may be lurking in the lungs or chest wall.

MUSC physicians have long championed the use of CT scans of the heart to detect blockages or narrowing of heart vessels as harbingers of a heart attack without the need for an invasive heart catheterization.

However, for a comprehensive diagnosis of coronary artery disease, MUSC, like most cardiovascular centers, had traditionally relied on several imaging modalities, such as cardiac catheterization, nuclear medicine or magnetic resonance (MR) scanners.

This technique could be the long coveted one-stop-shop test that allows us to look at the heart vessels, heart function and heart blood flow with a single CT scan and within a single breath-hold said Dr. Schoepf, the lead investigator of the study.

Based on their initial observations, Heart & Vascular Center physicians have launched an intensive research project aimed at systemically comparing the new scanning technique to conventional methods for detecting decreased blood supply in the heart muscle.

Their research has been significantly enhanced by the recent move to a new, state-of-the-art facility, MUSC Ashley River Tower, which provides MUSC physicians with the most cutting edge cardiovascular imaging equipment, all in one convenient, patient-friendly location.
