Brief Summary
The investigators' rationale was to evaluate whether a 64-slice CT scanner allows accurate measurement of computed tomographic changes in coronary artery flow profiles and whether CT flow measurements are suitable for classifying the significance and hemodynamic relevance of a stenosis and thereby supplement as a functional parameter for morphological stenosis analysis.
