“…In standing position, the lumbosacral angle decreases in relation to verticality of the spine, which is necessary to support the increase in weight, whereas the increase in lordosis angle reflects compensation by muscle contracture. The reduction of intervertebral disc height was highly significant ( p = 0.000083), undoubtedly due to body weight and muscle activation [11, 14, 17]. In particular, the reduction of disc height affects the posterior portion, whereas anteriorly, there was a slight increase, with major changes at L2–L3 and L3–L4 [18].…”

BackgroundPatients with low back pain frequently demonstrate recumbent magnetic resonance imaging (MRI) alterations not always related to homogeneous clinical symptoms. The purpose of this study was to evaluate and quantify the statistical significance of variations of some anatomical parameters of the lumbosacral spine and reveal occult disc pathologies from recumbent to upright position in patients with acute and chronic low back pain.Materials and methodsFifty-seven patients complaining of low back pain (27 women, 30 men) underwent dynamic lumbosacral MRI with a 0.25-T tilting system (G-scan Esaote). We settled five parameters for which variations have been evaluated: lumbosacral angle, lordosis angle, L3–L4 intersomatic disc height, L3–L4 interspinous processes distance, and widest anteroposterior dural sac diameter. Images were obtained in both recumbent and upright positions.ResultsStatistically significant differences [one-way analysis of variance (ANOVA), p = 0.0043] were found between each pair of values of parameters sampled in recumbent and upright positions. In 70 % of patients, on visual qualitative analysis only, an increment of disc protrusions and/or spondylolisthesis was found in the upright position; in three cases, in the upright position only, an interarticular pseudocyst was found.ConclusionsDynamic MRI with an open-configuration, low-field tilting MRI system is a feasible and promising tool to study degenerative pathology of the spine. Moreover, in cases of low back pain with negative MRI in the recumbent position or in patients with pain in the upright position only, tilting MRI permits visualization of occult spine and disc pathologies in patients with acute or chronic low back pain.

“…It provides an accurate morphological assessment of both osseous and soft tissue structures including intervertebral discs, spinal ligaments, and the neural elements. Dynamic weight bearing MRI has recently been championed as the preferred technique for pathology-specific diagnosis [5, 6]. Computed tomography in isolation lacks the soft tissue detail achieved with MRI scanning.…”

“…Recumbent imaging was found to have missed pathology in 15% of cases and underestimated it in 62% of cases. 21 This work included 13 cases of spondylolisthesis. The pros and cons of open positional imaging and routine scanning protocols have been discussed previously.…”
