Abstract:
A number of new magnetic resonance imaging techniques are offering excellent views of the cardiovascular system. These techniques can provide accurate information about chamber sizes, ventricular mass, and wall motion. Blood flow patterns can be analyzed to provide semiquantitative estimates of valvular regurgitation. Accurate measurements of the area and velocity of great vessel flow may provide the first truly quantitative magnetic resonance imaging estimates of shunt flow and regurgitant volumes. Future developments and improvements may lead to coronary artery imaging in clinical patients. In addition to these promising developments in magnetic resonance imaging, several other interesting imaging papers are discussed in this review of magnetic resonance and other imaging techniques.
