Nonenhanced ECG-gated quiescent-interval single shot MRA: Image quality and stenosis assessment at 3 tesla compared with contrast-enhanced MRA and digital subtraction angiography

Abstract

Overall image quality and specificity of QISS-MRA at 3T are diminished relative to CE-MRA. However, when image quality is adequate, QISS-MRA has high sensitivity and, thus, has potential use in patients with contraindications to gadolinium.
