Accelerated 4D flow imaging with variable-density cartesian undersampling and parallel imaging reconstruction
Methods Variable-density Poisson Disk Distribution (VD-PDD) undersampling was applied for 4D flow imaging. By applying VD-PDD independently at each time frame (Figure 1a), we achieved random undersampling in both the ky-kz plane and temporal domains. In addition, we applied an improved initial solution for SPIRIT to significantly improve reconstruction accuracy and robustness. We explored the d...
متن کاملClinical evaluation of aortic coarctation with 4D flow MR imaging.
PURPOSE To show that 4D Flow is a clinically viable tool for evaluation of collateral blood flow and demonstration of distorted blood flow patterns in patients with treated and untreated aortic coarctation. MATERIALS AND METHODS Time-resolved, 3D phase contrast magnetic resonance imaging (MRI) (4D Flow) was used to assess blood flow in the thoracic aorta of 34 individuals: 26 patients with co...
متن کاملHighly accelerated dynamic contrast enhanced imaging with prospective undersampling
Introduction: Dynamic contrast enhanced (DCE) imaging employs serial T1-weighted scans to quantify the pharmacokinetics of an injectable contrast agent. This allows assessment of tissue properties such as vascular permeability. Clinical applications of DCE, such as tumor characterization, will benefit from improvements in spatiotemporal resolution and volume coverage beyond what is possible tod...
متن کاملHighly Accelerated Free-breathing 4D Cardiac Imaging with CIRCUS Acquisition
INTRODUCTION 4D cardiovascular MRI applications typically require prolonged scan times and suffer from artifacts due to physiological motion. Compressed sensing (CS) and its combination with parallel imaging (PI) have recently emerged as valuable tools for accelerating MRI acquisitions by reconstructing images from undersampled k-space data. The required incoherent artifact in CS is usually ach...
