Golden-ratio rotated stack-of-stars acquisition for improved volumetric MRI

Automatic Bolus Analysis for DCE-MRI Using Radial Golden-Angle Stack-of-stars GRE Imaging

INTRODUCTION: In clinical 3D Dynamic Contrast-Enhanced MRI (DCE-MRI) of the abdomen, multiple phases of perfusion (pre-contrast, arterial, venous, delayed phases) are captured subsequently in breath-hold scans. Novel imaging and reconstruction techniques such as GRASP promise DCEMRI at a temporal resolution of only few seconds from a single, continuous image acquisition. This reduces the requir...

Improved real-time MRI of oral-velar coordination using a golden-ratio spiral view order

In speech research using real-time magnetic resonance imaging (RT-MRI), frame reconstruction is typically performed with a constant temporal resolution. However, a flexible selection of temporal resolution is desirable because of natural variations in speaking rate and variations in the speed of different articulators. In this work, a novel spiral golden-ratio temporal view order was applied to...

Golden-angle radial sparse parallel MRI: combination of compressed sensing, parallel imaging, and golden-angle radial sampling for fast and flexible dynamic volumetric MRI.

PURPOSE To develop a fast and flexible free-breathing dynamic volumetric MRI technique, iterative Golden-angle RAdial Sparse Parallel MRI (iGRASP), that combines compressed sensing, parallel imaging, and golden-angle radial sampling. METHODS Radial k-space data are acquired continuously using the golden-angle scheme and sorted into time series by grouping an arbitrary number of consecutive sp...
