Simultaneous static and time-resolved nonenhanced peripheral MR angiography

چکیده
Background Due to the association of gadolinium with nephrogenic systemic fibrosis in patients with renal insufficiency, nonenhanced methods for peripheral angiography such as quiescent interval single shot (QISS) and subtractive fast spin-echo are of increasing clinical interest. Despite the ability of these methods to depict peripheral vascular pathology, they have limited ability to display the arterial pulse wave which may aid in characterization of peripheral vascular disease. We describe a rapid nonenhanced MRA method that provides for static and time-resolved display of blood flow within the peripheral vasculature.

While nonenhanced magnetic resonance (MR) angiographic methods have been available since the earliest days of MR imaging, prolonged acquisition times and image artifacts have generally limited their use in favor of gadolinium-enhanced MR angiographic techniques. However, the combination of recent technical advances and new concerns about the safety of gadolinium-based contrast agents has spurre...
