Cardiac CT exhibits both clinical and cost benefits
December 1st 2007Increasing efforts to screen and diagnose coronary artery disease have used imaging modalities such as catheter angiography, ultrasound, and MRI. Electron-beam CT was, for a long time, the only CT system able to image the coronary arteries without motion artifacts. But multislice CT has advanced rapidly over the last decade, and state-of-the-art 64-slice and dual-source CT now offer high-quality imaging of the coronary arteries, myocardium, and valves, providing morphological and even functional information.
Dual-source CT advances coronary angiography
December 1st 2006Dual-source CT represents a significant advance for coronary CT angiography. In our preliminary experience, it has made CTA more robust and provided reliable assessment of vessel wall irregularities and stenoses without motion artifacts. Radiation exposure can be reduced significantly compared with conventional CTA.
