Quiescent Interval Single Shot MR Angiography
Introduction Given the frequency of renal functional impairment in patients with peripheral vascular disease (PVD) and concerns about nephrogenic systemic fibrosis, there is growing interest in unenhanced MRA (1,2). While promising, existing unenhanced MRA methods suffer from limitations that preclude robust clinical application for PVD. An ideal unenhanced method should be fast, easy to use, a...
متن کاملQuiescent-Interval Single-Shot Unenhanced Magnetic Resonance Angiography featuring Continuous Table Movement
Most recently, quiescent-interval single-shot (QISS) peripheral MRA [1] has been introduced as a fast and robust alternative to unenhanced MRA methods such as two-dimensional time of flight [2] and fresh blood imaging [3]. Being a single-shot technique, QISS is relatively robust in the presence of respiratory and bowel motion. The method, furthermore, is widely independent of the arterial peak ...
متن کاملHigh acceleration quiescent-interval single shot magnetic resonance angiography at 3T in patients with peripheral artery disease
Background Quiescent-Interval Single Shot (QISS) non-contrast MR angiography (QISS-MRA) is an emerging technique with growing evidence for its use in the evaluation of peripheral artery disease (PAD) at 1.5T [1,2]. The use of 3 Tesla MRI scans is becoming more common in clinical practice and offers the main advantage of roughly double the signal-to-noise ratio (SNR) than that of 1.5 Tesla MRI. ...
متن کاملThe diagnostic value of non-contrast enhanced quiescent interval single shot (QISS) magnetic resonance angiography at 3T for lower extremity peripheral arterial disease, in comparison to CT angiography
BACKGROUND The high incidence of renal insufficiency in patients with Peripheral Arterial Disease raises the concern for nephrogenic systemic fibrosis (NSF) with respect to contrast enhanced MRA. The risk of NSF is eliminated with non-contrast enhanced magnetic resonance angiography. The purpose of the current study is to compare image quality and diagnostic performance of non-contrast enhanced...
متن کاملEvaluation of Peripheral Arterial Disease with Nonenhanced Quiescent-Interval Single-Shot MR Angiography.
PURPOSE To assess the diagnostic performance of quiescent-interval single-shot (QISS) magnetic resonance (MR) angiography, a nonenhanced two-dimensional electrocardiographically gated single-shot balanced steady-state free precession examination for the evaluation of symptomatic chronic lower limb ischemia. MATERIALS AND METHODS For this prospective institutional review board-approved, HIPAA-...
