[Possibilities and limits of quantitative image analysis using magnetic resonance procedures].
Magnetic resonance imaging provides three-dimensional images of the heart with good spatial and temporal resolution. Therefore, right and left ventricular function can be assessed without assumptions regarding ventricular morphology. Depiction of intracardiac blood flow with gradient echo sequences permits estimation of the severity of valvular regurgitation. Using improved paramagnetic contrast media magnetic resonance imaging may be able to directly visualize regions of ischemic myocardium. Real-time imaging of the heart will be possible using echo planar techniques. Although quantification of cardiac parameters by MRI is still mainly a research tool, clinical applications will emerge in the near future.
