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.
Fat-Based Registration of Breast Dynamic Contrast Enhanced Water Images
Dynamic contrast-enhanced breast MRI scans take 5-10 minutes to acquire, so motion between the temporal phases is a common problem that must be corrected before post-processing.
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.
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. The Double-Echo Steady-State (DESS) sequence is often used for radiographic images of the knee.
Imaging and T2 Relaxometry of Short-T2 Connective Tissues in the Knee using Ultrashort Echo-Time Double-Echo Steady-State (UTEDESS)
Osteoarthritis is a whole-joint disease, however, it is currently challenging to image several tissues in the joint such as the menisci, tendons, and ligaments.
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.
