Upright Multi-Position Weight-Bearing MRI
| Specifications | THE FONAR UPRIGHT® WEIGHT-BEARING MRI (also known as the Stand-Up® MRI) |
| Unique Applications | Rotates patients from recumbent to upright |
| Comparative scans in both Upright and Recumbent positions | |
| Flexion, Extension, Standing, Sitting and Lateral Bending positions | |
| Scans patients in their position of symptoms | |
| Ideal for anxious and claustrophobic patients | |
| The only choice for patients that cannot lie down | |
