چکیده
HYPR TRICKS is an acquisition method that combines radial k-space trajectories, sampling k-space at different rates (TRICKS), and a new strategy for image reconstruction that uses highly constrained backprojection reconstruction (HYPR). This approach provides 3D time-resolved contrast-enhanced MR angiograms of the cerebral vessels with subsecond frame update times and submillimeter in-plane spatial resolution. Artifacts are suppressed, and signal-to-noise ratio is well maintained, by using HYPR reconstruction.

Time-resolved angiography: Past, present, and future.
The introduction of digital subtraction angiography (DSA) in 1980 provided a method for real time 2D subtraction imaging. Later, 4D magnetic resonance (MR) angiography emerged beginning with techniques like Keyhole and time-resolved imaging of contrast kinetics (TRICKS) that provided frame rates of one every 5 seconds with limited spatial resolution. Undersampled radial acquisition was subseque...
متن کاملAccelerated 3D Time-Resolved MR Angiography using Cartesian HYPR LR Reconstruction
INTRODUCTION In many MR applications, it is desirable to achieve high spatial and temporal resolution at the same time, such as contrast-enhanced MR angiography (CE-MRA). However, fully-sampled Cartesian acquisition for large matrices is extremely time consuming and precludes the simultaneous achievement of both goals. Several Cartesian undersampling methods, such as CAPR [1], TRIPPS [2] and va...
متن کاملAccelerated Time Resolved Inflow with 3D Multi-Echo Radial Trajectories
Introduction: Arterial spin labeling (ASL) sequences which utilize tagging schemes to images the flow of blood have emerged as effective techniques for the non-contrast angiography; however, these techniques typically suffer from long acquisition times, sensitivity to tag delay parameters, and uncertain performance in cases of complex flow [1-3]. To mitigate these errors, we have previously dem...
متن کاملFast whole-brain 4D contrast-enhanced MR angiography with velocity encoding using undersampled radial acquisition and highly constrained projection reconstruction: image-quality assessment in volunteer subjects.
We report on the image quality obtained by using fast contrast-enhanced whole-brain 4D radial MRA with 0.75-second temporal resolution, isotropic submillimeter spatial resolution, and velocity encoding (HYPRFlow). Images generated by HYPR-LR by using the velocity-encoded data as the constraining image were of diagnostic quality. In addition, we demonstrate that measurements of shear stress with...
متن کاملRecent advances in 3D time-resolved contrast-enhanced MR angiography.
Contrast-enhanced magnetic resonance angiography (CE-MRA) was first introduced for clinical studies approximately 20 years ago. Early work provided 3-4 mm spatial resolution with acquisition times in the 30-second range. Since that time there has been continuing effort to provide improved spatial resolution with reduced acquisition time, allowing high resolution 3D time-resolved studies. The pu...
