The 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 کاملNon-contrast peripheral angiography at 3T using QISS: improving venous suppression
Background Quiescent Interval Single Shot (QISS) has emerged as a robust technique for non-enhanced angiography of peripheral arteries (1). It has been clinically validated with contrast enhanced magnetic resonance angiography (CE-MRA) and digital subtraction angiography (DSA) (2,3). Both of these validation studies were performed at 1.5T field strength. Although the initial experience with QIS...
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 کاملAnkle-brachial index (ABI) and quiescent-interval single shot (QISS) MRA in peripheral arterial disease (PAD): comparison of diagnostic accuracy and need for additional imaging procedures
Background PAD is a major cause of morbidity and accurate diagnosis is essential for optimal patient management. ABI measurement is the initial diagnostic test of choice however, accuracy is sometimes limited, e.g. in diabetic patients and with vessel calcification. Additional imaging with CTA, MRA, or DSA is often required prior to revascularization. QISS MRA is a rapid, operator-independent n...
