Answer

MRA is useful for imaging large and small vessels. Although it was initially considered to provide inadequate images, this is no longer the case. With improved imaging capabilities, MRA can be used not only to diagnose but also to help plan the type of indicated intervention.

A study that compared MRA with conventional angiography in regard to quality of life and cost-effectiveness found that although MRA was nearly 20% cheaper, there was no difference in quality of life. [9]
