[Magnetic-resonance imaging under degenerative changes in lumbar spine: state of the art]

Magnetic resonance imaging (MRI) of lumbar spine is a very frequent examination in any computer tomography unit. However, there are still no scan standards or standards for scan interpretation in the world's medical community. In this article based on our experience we describe common problems encountered by a radiologist during MRI examination of lumbar spine and its subsequent description. The literature survey and analysis are presented with a summary of current recommendations. We examined routine sequences, which could be included in MRI protocol, discussed common terminology, and showed the incidence of different pathologies. The special emphasis is made on assessing lumbar canal stenosis. In this article we focus on qualitative and quantitative criteria of lumbar spinal stenosis.
