title: Magnetic resonance angiography: today and tomorrow.
abstract: Magnetic resonance angiography (MRA) has enjoyed enthusiastic success at many research institutions where it is now routinely used in place of invasive x-ray angiography (XRA) for a variety of applications. While the physical principles of MRA are well understood, there is still plenty of opportunity for growth in the coming years. Recent improvements in instrumentation have permitted more rapid acquisition and manipulation of larger data sets. Instruments in the future are sure to continue this trend as computer hardware becomes more capable and less expensive. New clinical applications will also expand the utility of MRA beyond its current use. MRA is already being used in peripheral vessels and it appears to have great potential in the abdomen. Research into MRA methods for coronary vessel imaging is also beginning to show intriguing results. In addition, preliminary research results suggest that interventional MRA may one day become a reality.
