Magnetic resonance angiography continues to develop both in technical capabilities and in clinical applications. Head and neck MR angiography is now in common use and is being compared to digital subtraction angiography (DSA) on a daily basis. New approaches to MR angiography in the abdomen and thorax and peripheral areas are making progress. Even coronary angiography is likely to fall prey to MR angiography and the prowess of those designing new techniques. The role of contrast agents in MR angiography is becoming more evident; contrast agents are likely to play an important role in the future. Furthermore, quantitative flow velocity measurements of major vessels are also possible and are of interest to clinicians for blood flow information. This review covers these and other recent developments in MR angiography, including both technical and clinical developments.
