Magnetic resonance angiography of the neck. Technical issues.
This article reviews the technical issues faced when using any of several methods of MR angiography that are in widespread use today. Both time-of-flight and phase-contrast¿based techniques are addressed. Artifacts as a function of echo times, vessel contrast, and vessel contrast enhancement are key issues. Selective visualization of arteries or veins is discussed also.
