Single CT scan could diagnose heart disease.

A comprehensive diagnosis of heart disease could be possible with a single computed tomography scan, according to a report that appeared in the March 4 issue of Circulation.

Comprehensive heart disease diagnosis is difficult. Clinicians at most cardiovascular centers traditionally have relied on several imaging modalities and although CT can provide images of heart structures, it cannot detect blood flow.

Researchers at the Medical University of South Carolina in Charleston, S.C., developed a dual-source CT scanner technique that enables comprehensive diagnosis of heart disease based on a single CT scan.

They added two x-ray spectra to gain a static image of the coronary arteries and the heart muscle. This dual-energy technique helps to map the blood distribution within the heart muscle and pinpoint areas with decreased blood supply.

CT scans are less invasive than other techniques, and a single-scan technique would provide considerable cost savings, as well as greater convenience and reduced radiation exposure for patients, according to the researchers.
