The objective of the review was to examine the evidence comparing upright to supine MRI of the lumbar spine.
A literature search identified 14 articles comparing data where subjects had been scanned in both supine and upright positions on the same scanner. Lumbar spine anatomy is dynamic and therefore subject to morphological changes when transitioning from the supine to the upright position. There is strong evidence to suggest structural changes in spinal morphology due to radiographic positioning, and that upright positioning is better for evaluating spondylolisthesis.
It has been demonstrated that the scanning position is important in the outcome of the MRI examination of the lumbar spine. With this in mind, it would be beneficial for guidance to be written and adopted to improve the consistency and quality of scanning.
As upright MRI occupies a niche in the scanning sector, many professionals are unaware of its capabilities. This article aims to increase awareness of the use of upright MRI in evaluating the lumbar spine.
本综述旨在比较腰椎磁共振成像（MRI）仰卧位与直立位检查的证据。
通过文献检索，共确定了 14 篇比较受试者在同一台扫描仪上仰卧位和直立位两种体位下扫描数据的文章。腰椎解剖结构具有动态性，因此在从仰卧位向直立位转换时会发生形态学变化。有强有力的证据表明，由于影像学定位，脊柱形态会发生结构变化，并且直立位更有利于评估脊椎滑脱症。
已经证明，扫描体位对腰椎 MRI 检查的结果很重要。有鉴于此，编写和采用指导意见将有助于提高扫描的一致性和质量。
由于直立 MRI 在扫描领域占据一席之地，许多专业人员并不了解其功能。本文旨在提高人们对直立 MRI 在评估腰椎方面的应用的认识。
