II. Indications
- Heart functional studies
- Noninvasive Coronary Artery stenosis evaluation
- Right and left ventricular function evaluation
- Great Vessel evaluation (aorta and vena cava)
- Anomalous Coronary Artery evaluation
- Heart structural studies
- Cardiac mass evaluation
- Congenital Heart Disease evaluation
III. Efficacy: Coronary MRA
- Test Specificity: 58% (42% False Positive Rate)
-
Test Sensitivity
- Overall sensitivity for >50% coronary stenosis: 88%
-
Clinically Significant disease: 93%
- Left main Coronary Artery Disease
- Three vessel Coronary Artery Disease
IV. Advantages
- Noninvasive
- Relatively sensitive for significant disease
- But misses 7% of these cases
V. Disadvantages
- Long study (average of 70 minutes, may be >2 hours)
- High False Positive Rate (42%)
VI. Interpretation: Findings suggestive of coronary disease
- Coronary stenosis and myocardial perfusion
- Myocardial metabolism
- Wall motion abnormalities on stress testing
- Differentiate infarcted from viable Myocardium
- Uses delayed hyperenhancement imaging
