Summary
Magnetic resonance imaging (MRI) use has rapidly expanded beyond neurology to orthopedics and primary care. Primary care physicians now utilize this advanced imaging technology more frequently, showing increased knowledge of its applications and costs.
Area of Science:
- Radiology
- Medical Imaging
- Health Services Research
Background:
- Magnetic resonance imaging (MRI) is a new, expensive imaging technology with expanding clinical applications.
- Initial use focused on neurology, but indications quickly broadened to spine, pelvis, bone marrow, and joints.
- Concerns exist regarding the appropriate and cost-effective utilization of MRI.
Purpose of the Study:
- To examine the evolution of MRI scanning patterns in central Massachusetts.
- To assess primary care physicians' knowledge, attitudes, and utilization of MRI.
Main Methods:
- Surveyed two MRI centers in central Massachusetts for scan data and ordering physician specialties.
- Distributed questionnaires to primary care physicians in Worcester County regarding MRI knowledge, attitudes, and use.
Main Results:
- MRI utilization patterns have significantly changed over time.
- Orthopedics has shown the largest increase in MRI use, now exceeding neurology.
- Primary care physician utilization of MRI has doubled, with users demonstrating better understanding of indications and costs.
Conclusions:
- MRI utilization patterns have evolved rapidly.
- Primary care physicians are increasingly requesting MRI scans, indicating growing adoption of this technology.
