Kidney DCE-MRI aims at both qualitative assessment of kidney anatomy and quantitative assessment of kidney function by estimating the tracer kinetic (TK) model parameters. Accurate estimation of TK model parameters requires an accurate measurement of the arterial input function (AIF) with high temporal resolution. Accelerated imaging is used to achieve high temporal resolution, which yields under-sampling artifacts in the reconstructed images. Compressed sensing (CS) methods offer a variety of… Expand

Modeling dynamic radial contrast enhanced MRI with linear time invariant systems for motion correction in quantitative assessment of kidney function
This work introduces a novel linear time invariant (LTI) model to characterize DCE-MR data for different tissue types within a volume and approximate the LTI model as a sparse sum of first order LTI functions to introduce robustness to motion and sampling artifacts. Expand
A Deep Cascade of Convolutional Neural Networks for Dynamic MR Image Reconstruction
A framework for reconstructing dynamic sequences of 2-D cardiac magnetic resonance images from undersampled data using a deep cascade of convolutional neural networks (CNNs) to accelerate the data acquisition process is proposed and it is demonstrated that CNNs can learn spatio-temporal correlations efficiently by combining convolution and data sharing approaches.

Undersampled radial MRI with multiple coils. Iterative image reconstruction using a total variation constraint
An iterative reconstruction method for undersampled radial MRI which is based on a nonlinear optimization, allows for the incorporation of prior knowledge with use of penalty functions, and deals with data from multiple coils is developed. Expand
PET Image Reconstruction Using Deep Image Prior
Quantification results based on simulation and real data show that the proposed reconstruction framework can outperform Gaussian post-smoothing and anatomically guided reconstructions using the kernel method or the neural-network penalty. Expand

This work formulated the proposed DECT joint reconstruction framework as a constrained optimization problem and solved it using the alternating direction method of multipliers (ADMM) algorithm and shows that the proposed method can outperform the reference denoising methods. Expand
MR Image Reconstruction From Highly Undersampled k-Space Data by Dictionary Learning
Dramatic improvements on the order of 4-18 dB in reconstruction error and doubling of the acceptable undersampling factor using the proposed adaptive dictionary as compared to previous CS methods are demonstrated. Expand
MRI-Measurement of Perfusion and Glomerular Filtration in the Human Kidney With a Separable Compartment Model
The separable compartment model is feasible for application in humans and sufficiently robust for a pixel analysis, and increased filtration values compared with the Patlak model suggest that the difference in accuracy observed in animal studies is relevant in humans. Expand
Coil compression for accelerated imaging with Cartesian sampling
A new coil compression technique for Cartesian sampling is presented that exploits the spatially varying coil sensitivities in these nonsubsampled dimensions for better compression and computation reduction in 3D acquisitions and iterative reconstructions. Expand
Bulk motion‐compensated DCE‐MRI for functional imaging of kidneys in newborns
Evaluation of kidney function in newborns with hydronephrosis is important for clinical decisions. Dynamic contrast‐enhanced (DCE) MRI can provide the necessary anatomical and functional information.Expand
Deep learning with domain adaptation for accelerated projection‐reconstruction MR
A novel deep learning approach with domain adaptation is proposed to restore high‐resolution MR images from under‐sampled k‐space data to solve the problem of streaking artifact patterns in magnetic resonance imaging. Expand
