Synopsis

This presentation overviews non-contrast-enhanced techniques for magnetic resonance angiography (MRA). Non-contrast-enhanced MRA can be performed using a variety of techniques. This presentation describes the main non-contrast-enhanced MRA techniques, their contrast mechanisms, as well as their clinical applications. Strengths and drawbacks of non-contrast-enhanced MRA will also be discussed. This presentation also reviews emerging methods that hold promise for expanding the role of non-contrast-enhanced MRA in the clinical setting.
