Letter to the editor concerning 'nucleus pulposus deformation in response to lumbar spine lateral flexion: an in vivo MRI investigation' by Fazey PJ et al. (2010) Eur Spine J 19:1115-1120.

摘要

With interest I read the article by Fazey et al. [1] describing a meticulously conducted study in which they used an image analysis software (NIH Image-J, Bethesda, USA) to investigate hydration pattern within the lumbar interverte-bral disc (IVD) in response to lateral flexion. I want to commend on their effort in seeking to share this information through publication of their work. Such novel method employed the use of linear pixel samples across the width of the disc from T2-weighted magnetic resonance imaging (MRI) images in order to determine the magnitude and direction of the displacement of the nucleus pulposus (NP) in lumbar IVD.
