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 …

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 …

Time‐resolved contrast‐enhanced magnetic resonance angiography of the brain is
challenging due to the need for rapid imaging and high spatial resolution. Moreover, the …

Sensitivity encoding (SENSE) and partial Fourier techniques have been shown to reduce
the acquisition time and provide high diagnostic quality images. However, for time‐resolved …

Purpose To present a new 4D method that is designed to provide high spatial resolution MR
angiograms at subsecond temporal resolution by combining different techniques of view …

Purpose To investigate the feasibility of using time‐of‐flight (TOF) images as a constraint in
the reconstruction of a series of highly undersampled time‐resolved contrast‐enhanced MR …

Sufficient temporal resolution is required to image the dynamics of blood flow, which may be
critical for accurate diagnosis and treatment of various intracranial vascular diseases, such …

Contrast‐enhanced magnetic resonance angiography is challenging due to the need for
both high spatial and temporal resolution. A multishot trajectory composed of pseudo …

BACKGROUND AND PURPOSE: A method is presented for high-temporal-resolution MR
angiography (MRA) using a combination of undersampling strategies and a high-field (3T) …

A method for reconstruction of time‐resolved MRI called highly‐constrained backprojection
(HYPR) has been developed. To evaluate the HYPR reconstruction in relation to data …
