Overview
Brief Summary
The purpose of the study is to assess the diagnostic accuracy of a combined use of non-invasive coronary angiography with multi-slice computed tomography (MSCT) and stress cardiac magnetic resonance (CMR) imaging in patients with obstructive lesions on MSCT and with low to intermediate pre-test likelihood of coronary artery disease (CAD) as compared to invasive coronary angiography (CAG) and Fractional Flow Reserve (FFR) measurements.

Outcomes
Primary Outcomes
Diagnostic accuracy to detect ischemia with stress CMR compared to FFR
Time Frame: one month
The diagnostic accuracy of MSCT coronary angiography in combination with stress CMR imaging as compared to invasive CAG and FFR measurement, as a standard of reference to detect obstructive and hemodynamically significant stenoses in patients with low to intermediate pre-test likelihood of CAD.
Secondary Outcomes
- Predictive value for treatment strategy of a non-invasive strategy with MSCT and stress CMR compared to an invasive strategy(one month)
