LGGS: Longitudinal MRI Reconstruction via Guided Group Sparsity
Nikola Janjušević, Hersh Chandarana, Yao Wang +1
Serial MRI is routinely performed in current clinical practice for disease surveillance and applications such as MR-guided radiotherapy. However, long MRI scan times increase costs…
Distortion-Free High-Resolution PROPELLER-DWI: Technical Advances and Initial Demonstration for the Prostate
Jingjia Chen, Kun Zhou, Haoyang Pei +7
Purpose: To develop and evaluate an integrated acquisition and reconstruction framework for distortion-free, high-resolution prostate diffusion-weighted imaging (DWI). Methods: PRO…
Free-Breathing PDFF and R2* Quantification at 0.55T: Reduced Respiratory Motion Sensitivity and a Time-Resolved 4D MRI Approach
Jeffery Wong, Jingjia Chen, Ding Xia +5
Purpose: Free-breathing multi-echo MRI enables hepatic PDFF/R2* quantification without breath-holds, but respiratory motion can affect R2* estimation through motion-induced field v…
Masked and Predictive Self-Supervised Pretraining for Brain MRI: Effects of Objective Design on Disease Detection
Esra Ergün, Hersh Chandarana, Dan Sodickson +2
MRI self-supervised learning (SSL) has largely emphasized segmentation and dense prediction, while controlled studies of how alternative pretraining objectives shape transferable r…
GRASP MRI: A Decade of Innovation from Bench to Bedside
Li Feng, Kai Tobias Block, Hersh Chandarana +1
GRASP (Golden-angle RAdial Sparse Parallel) MRI has emerged as one of the most influential motion-robust dynamic MRI frameworks over the past decade. By combining continuous golden…
Respiratory Motion Management in Abdominal MRI: Revisiting the Gap Between Technical Advances and Clinical Translation
Li Feng, Hersh Chandarana
The inherently slow acquisition speed of MRI makes abdominal imaging highly sensitive to respiratory motion artifacts. Since the early days of MRI, the development of respiratory m…
