Automated MRI Field of View Prescription from Region of Interest Prediction by Intra-Stack Attention Neural Network
Autor: Ke Lei, Ali B. Syed, Xucheng Zhu, John M. Pauly, Shreyas V. Vasanawala
Publikováno v: Bioengineering, Vol 10, Iss 1, p 92 (2023)
Manual prescription of the field of view (FOV) by MRI technologists is variable and prolongs the scanning process. Often, the FOV is too large or crops critical anatomy. We propose a deep learning framework, trained by radiologists’ supervision, fo

Autor: Karthik M. Sundaram, Jarrett Rosenberg, Ali B. Syed, Stephanie T. Chang, Andreas M. Loening
Publikováno v: Radiol Imaging Cancer
PURPOSE: To assess whether administration of intramuscular (IM) glucagon improves T2-weighted image quality at multiparametric MRI (mpMRI) of the prostate. MATERIALS AND METHODS: In this Health Insurance Portability and Accountability Act–compliant

Rapid fat–water separated T 1 mapping using a single‐shot radial inversion‐recovery spoiled gradient recalled pulse sequence
Autor: Zhitao Li, Manoj Mathew, Ali B. Syed, Li Feng, Ryan Brunsing, John M. Pauly, Shreyas S. Vasanawala
Publikováno v: NMR in Biomedicine. 35
Tsub1/submapping is increasingly used in clinical practice and research studies. With limited scan time, existing techniques often have limited spatial resolution, contrast resolution and slice coverage. High fat concentrations yield complex errors i

Accelerated two-dimensional phase-contrast for cardiovascular MRI using deep learning-based reconstruction with complex difference estimation
Autor: Julio A. Oscanoa, Matthew J. Middione, Ali B. Syed, Christopher M. Sandino, Shreyas S. Vasanawala, Daniel B. Ennis
Publikováno v: Magnetic resonance in medicineREFERENCES. 89(1)
To develop and validate a deep learning-based reconstruction framework for highly accelerated two-dimensional (2D) phase contrast (PC-MRI) data with accurate and precise quantitative measurements.We propose a modified DL-ESPIRiT reconstruction framew

Free‐breathing mapping of hepatic iron overload in children using 3D multi‐echo UTE cones MRI
Autor: Joseph Y. Cheng, Timothy J. Colgan, Christopher M. Sandino, Ann Shimakawa, Youngwook Kee, Diego Hernando, Ali B. Syed, Shreyas S. Vasanawala
Publikováno v: Magnetic Resonance in Medicine. 85:2608-2621
PURPOSE To enable motion-robust, ungated, free-breathing R2∗ mapping of hepatic iron overload in children with 3D multi-echo UTE cones MRI. METHODS A golden-ratio re-ordered 3D multi-echo UTE cones acquisition was developed with chemical-shift enco

Rosette Trajectories Enable Ungated, Motion‐Robust, Simultaneous Cardiac and Liver T 2 * Iron Assessment
Autor: Marcus T. Alley, Frank Ong, Evan J. Zucker, Ali B. Syed, Nicholas Dwork, Shreya Ramachandran, Christopher M. Sandino, John M. Pauly, Shreyas S. Vasanawala, Adam Bush
Publikováno v: Journal of Magnetic Resonance Imaging. 52:1688-1698
BACKGROUND Quantitative T2 * MRI is the standard of care for the assessment of iron overload. However, patient motion corrupts T2 * estimates. PURPOSE To develop and evaluate a motion-robust, simultaneous cardiac and liver T2 * imaging approach using

Abstract 10639: Abbreviated Cardiac Magnetic Resonance Imaging versus Echocardiography for Interval Assessment of Systolic Function in Duchenne Muscular Dystrophy: Patient Satisfaction, Clinical Utility and Image Quality
Autor: Hamsika Chandrasekar, Beth D Kaufman, Shreyas Vasanawala, Meaghan Beattie, Ali B Syed, Shiraz A Maskatia
Publikováno v: Circulation. 144
Introduction: Interval assessment of systolic function in patients with Duchenne Muscular Dystrophy (DMD) is challenging by echocardiography (echo). Cardiac magnetic resonance imaging (CMR) has been limited due to study duration and patient experienc
