pright magnetic resonance imaging for evaluation of lateral recess stenosis of the lumbar spine

pright MRI, as a non-invasive diagnostic modality, is capable of demonstrating an incr ease in lateral recess stenosis under axial loading. However, the reduced image quality of the applied 0.25 Tesla scanner, the limits of the measurement accuracy as well as the restrictedly investig able patient collective have to be taken into account in a limiting manner. The extent to which upright MRI can support future surgical indications as a complementary imaging modality remains to be investigated.
