Acquisition & Reconstruction Methods
In addition to numerous specific application areas, our group spends considerable time developing new MRI techniques that can be applied broadly. These include RF pulse design, MRI pulse sequences, reconstruction algorithms and image analysis tools, as well as "packages" that combine some of these elements.
Estimation of Multiple Tissue Parameters Using the DESS Sequence
The Double-Echo Steady-State (DESS) sequence, which produces undistorted, SNR-efficient 3D scans, can provide estimates of multiple tissue parameters.
Rapid Volumetric Quantification of Cartilage Biochemistry with MRI
Detection of changes in cartilage glycosaminoglycan (GAG) content and distribution are vital for early diagnosis of osteoarthritis (OA) and potential treatment monitoring.
Accelerated 3D Multispectral MRI with Robust Principal Component Analysis
We have developed a method to acquire diagnostic MR images in 2-3 minutes to help millions of people who have complications related to metal devices, commonly hip replacements, knee replacements or spinal fixations.
Artifact-Reduced Imaging of Biopsy Needles with 2D Multispectral Imaging
We have validated the use of an MR imaging method that reduces the image artifacts due to metal objects for tracking biopsy needles in MR-guided procedures.
MRI Monitoring of Focused Ultrasound Sonications Near Metallic Hardware
We previously developed a method for imaging temperature changes in tissue near metal hardware; here we evaluate its use to monitor MR-guided focused ultrasound treatments.
Super-Resolution Musculoskeletal MRI Using Deep Learning
In this manuscript, we have demonstrated a method termed ‘DeepResolve’, which can transform low-resolution magnetic resonance images (MRI) into higher-resolution images.
