Abstract
Magnetic resonance angiography (MRA) is a noninvasive imaging method for the evaluation of the blood vessels. Images of the blood vessels can be generated using a variety of MR techniques with or without the need for exogenous intravenous contrast. Technical advances in hardware and software development coupled with the increasing availability of more powerful magnets have greatly improved the imaging capabilities of MRA. Thus, clinicians are increasingly relying on MRA as a tool for vascular assessment. The technological developments, advantages, limitations, and indications for MRA are discussed in detail in this article.
