Accelerated 4D flow imaging using randomly undersampled echo planer imaging with compressed-sensing reconstruction

Introduction 2D phase contrast (PC) CMR is currently the standard clinical imaging sequence for evaluation of blood flow [1]. Recently, 3D time-resolved PC CMR (4D-PC) has been used for quantification and visualization of blood flow in all three directions of a volume [2]. However, such acquisitions require long scan times (often 10-20 minutes), which reduces its clinical feasibility and leads ...

Compressed sensing reconstruction for undersampled breath-hold radial cine imaging with auxiliary free-breathing data.

PURPOSE To improve compressed sensing (CS) reconstruction of accelerated breath-hold (BH) radial cine magnetic resonance imaging (MRI) by exploiting auxiliary data acquired between different BHs. MATERIALS AND METHODS Cardiac function is usually assessed using segmented cine acquisitions over multiple BHs to cover the entire left ventricle (LV). Subjects are given a resting period between adj...

Sparse BLIP: BLind Iterative Parallel imaging reconstruction using compressed sensing.

PURPOSE To develop a sensitivity-based parallel imaging reconstruction method to reconstruct iteratively both the coil sensitivities and MR image simultaneously based on their prior information. METHODS Parallel magnetic resonance imaging reconstruction problem can be formulated as a multichannel sampling problem where solutions are sought analytically. However, the channel functions given by...

Accelerated three-dimensional cine phase contrast imaging using randomly undersampled echo planar imaging with compressed sensing reconstruction.

The aim of this study was to implement and evaluate an accelerated three-dimensional (3D) cine phase contrast MRI sequence by combining a randomly sampled 3D k-space acquisition sequence with an echo planar imaging (EPI) readout. An accelerated 3D cine phase contrast MRI sequence was implemented by combining EPI readout with randomly undersampled 3D k-space data suitable for compressed sensing ...

PROMISE: parallel-imaging and compressed-sensing reconstruction of multicontrast imaging using SharablE information.

PURPOSE A typical clinical MR examination includes multiple scans to acquire images with different contrasts for complementary diagnostic information. The multicontrast scheme requires long scanning time. The combination of partially parallel imaging and compressed sensing (CS-PPI) has been used to reconstruct accelerated scans. However, there are several unsolved problems in existing methods. ...
