Basic concepts in magnetic resonance angiography.

The field of MR angiography is becoming well-established and is finding its way into the general MR imaging practice. The number of acquisition methods and the supporting physics can be complex; however, once the basic concepts are understood an intuition regarding the basic use of MR angiography and some of the tradeoffs such as scan time, resolution, and coverage associated with different MR angiography methods can be developed. Table 3 summarizes typical applications of several different MR angiography techniques mentioned herein.
