BMR Publication Highlights
The following are general descriptions of recent highlights from BMR publications. You may also view a complete list of BMR group publications.
Automatic Renal Segmentation for MR Urography Using 3D-GrabCut and Random Forests
A new, automated workflow uses dynamic MR images of the kidney to segment portions of the kidney and quantitatively characterize regional kidney function.
2D Multi-Spectral Imaging For Fast MRI Near Metal
This approach offers a fast (tens of seconds per slice) approach to MRI near metal while correcting much of the signal loss, distortion and abnormally bright signal that can occur near implanted metal.
Improved Field Mapping Near Metal
Reducing the noise and distortion in magnetic field maps near metal implants allows for better visualization of the anatomy near the implant.
Imaging and T2 Relaxometry of Short-T2 Connective Tissues in the Knee using UTEDESS
Osteoarthritis is a whole-joint disease, but it is currently challenging to image some of the tissues in the knee.
A Simple Analytic Method for Estimating T2 in the Knee from DESS
MRI measurements of the relaxation time T2 can help estimate the progression of diseases such as osteoarthritis and its associated tissue deterioration.
Imaging of Metabolic Activity in Osteoarthritis with PET/MRI
Osteoarthritis (OA) is a chronic, degenerative disease of the joint that is characterized by degeneration affecting all tissues in the joint.
Cluster Analysis for Identifying Focal Cartilage Defects
A new visualization and cluster analysis tool helps identify focal cartilage T2 and T1rho relaxation time defects in the femoral condyles of an ACL-injured population.
Metallic Implant Estimation Using Susceptibility Mapping
Magnetic field patterns can be used to identify the location and shape of metal devices and render them on images.
MRI with Compressed Sensing and Variable View Sharing
A new sampling pattern enables retrospective selection of frame rates in MRI to allow for different spatiotemporal resoluiton tradeoffs and protocol optimization for different imaging applications.
MR Thermometry Near Metal
This novel development enables non-invasive temperature measurement using MRI (MR thermometry), in the vicinity of implanted metallic devices such as joint replacements or fixation hardware.
