3D Non-Contrast-Enhanced MRA Using Flow-Sensitive Dephasing (FSD) Prepared Balanced SSFP: Identification of the Optimal First-Order Gradient Moment
نویسندگان
چکیده
Introduction: A non-gadolinium-enhanced MRA technique using ECG-triggered 3D balanced SSFP with flow-sensitive dephasing (FSD) preparation has recently been developed and validated in the distal lower extremities of healthy volunteers [1]. The FSD’s first-order gradient moment, m1, is shown to be the most important parameter to determine angiographic quality. A suboptimal m1 may result in venous contamination or incomplete arterial delineation. This work aimed to develop an m1-scout approach to rapidly identify the optimal m1 for FSD-based noncontrast MRA.

Non Contrast MRA of the Hand in Patients with Raynauds disease using Flow Sensitized Dephasing Prepared SSFP
Introduction Raynauds disease is vasospastic disorder of the digital arteries. 3D contrast-enhanced (CE) MRA is increasingly utilized for patients with Raynauds. Safety concerns with contrast administration in patients with renal insufficiency has led to a renaissance of non-contrast MRA (NC-MRA). NC-MRA strategies employing 3D half-Fourier FSE [1] or SSFP [2] have shown great promise but vario...

Fig. 3. FSD gradient strength has significant effect on arterial SNR and image quality score, and also substantial effect on artery-vein CNR (p-value shown in each panel). All five gradient strengths were able to generate MRA images with satisfactory diagnostic quality. G=10mT/m resulted in the highest SNR, CNR, and image score (* indicates significant difference from other groups using paired ...
متن کاملNon-Contrast MRA Based-on SSFP
Conventional non-contrast MRA techniques, including time-of-flight (TOF) and phase contrast (PC) methods have not been widely used in clinical practice due to their lengthy acquisition times and potential overestimation of the severity of stenosis due to stagnant or complex flow. However, the TOF phenomenon has become the basis for a variety of MRA techniques that utilize magnetization preparat...

متن کامل3D flow-insensitive vessel wall imaging using T2PREP PSIR with SSFP
Introduction Double Inversion Recovery (DIR) [1] and Flow Sensitive Dephasing (FSD) [2] have been used to suppress arterial signal in vessel wall imaging. However, the “black blood” effect of DIR and FSD depends on blood flow, which makes these techniques less effective with slow or in-plane flow. In this work, T1 and T2 differences between blood and vessel wall were exploited using a T2-prepar...
