1.5T MRI or Open Permanent-Magnet MRI?
MRI system selection should be based on the intended examination mix, expected patient volume, site conditions, infrastructure requirements and future clinical development rather than field strength alone.
Consider 1.5T When
The project requires a general-purpose high-field MRI platform, broader advanced imaging functions, multi-channel acquisition and higher clinical throughput potential.
Consider 0.5T When
Open patient access remains a major requirement, while a higher-field permanent-magnet platform is preferred over a 0.35T system.
Consider 0.35T When
The primary requirement is routine MRI in an open permanent-magnet architecture with a comparatively simpler system concept.
