The purpose of this exhibit is:
1.) To review the technical capabilities and limitations of existing low-field MRI systems
2.) To learn about the available MR pulse sequences for clinical imaging at low field
3.) To explore the feasibility of low field MR imaging research in resource-limited settings
4.) The understand the state of quality control procedures for low-field MR systems
A review of the technical abilities and limitations of low-field MR systems
- Limitation of the main field (B0) strength for permanent magnets
- Unique installation challenges for a magnet that is always “on”
- RF receiver chain design and coil availability
- Gradient system performance
Available MR pulse sequences for clinical imaging
- Structural imaging capabilities and example images
- Quantitative imaging – what we can and cannot do
- Contrast agent performance considerations at low-field
Feasibility of imaging research in resource-limited settings
- Research utilization – experiences from our institution
- Image management and post-processing in settings with limited digital infrastructure.
The state of quality control procedure for low-field MR systems
- The state of accreditation for low-field systems
- Existence of phantoms for low-field Quality Control procedures
Future directions and summary
