经典Pfirrmann grade诊断椎间盘退变带来的不确定性 BACKGROUND CONTEXT: Pfirrmann grading can be used to assess intervertebral disc degeneration (IVDD). There is growing evidence that IVDD is not simply a structural disorder but also involves changes to the substructural characteristics of the disc. Whet...
Objective:To find the MRI characteristics of the lumbar intervertebral disc degeneration in patients less than 30 years old with low back pain, and try to evaluate the correlations between Pfirrmann’s grading scale and intervertebral disc bugle and intervertebral disc protrution. Material and Methods...
Grade V: the structure of the disc is inhomogeneous, with a hypointense black signal intensity. The distinction between nucleus and annulus is lost, and the disc space is collapsed. Grading is performed on T2-weighted Mid-sagittal fast spin-echo images....
Grading is performed on T2-weighted Mid-sagittal fast spin-echo images. Pfirrmann腰椎间盘突出MRI分级是一种很直观的分级,是MRI横断面上突出间盘和神经跟的关系确定的一种分级(如下图所示)。 Pfirrmann I级 突出间盘与神经跟无接触 Pfirrmann II级 突出间盘与神经根接触,神经根无移位 Pfirrmann III级 突出间...
Objective: To investigate the predictive value of material separation technology of spectral CT in Pfirrmann grading of lumbar intervertebral disc degeneration. Methods: Retrospective analysis was performed on 30 patients with lumbar disc herniation in our hospital from October 2020 to Feb...
Degeneration degrees of cervical intervertebral discs were evaluated by the Pfirrmann grading standard based on the preoperative cervical MRI. The weighted Kappa test was used to analyze the consistency of evaluations between different observers of the Pfirrmann scoring system and the McAfee grading system...

cells in intervertebral discs with different grade of Pfirrmann grading system. Method :Human nucleus pulposus cells were isolated by collagenase digestion method and cultured.they were grouped based on the Pfirrmann grading system. Group A represents grade II. Group B represents grade III. Group...
It is a simple and effective disc degeneration grading system.%目的 比较不同Pfirmiann分级椎间盘内髓核细胞的生物学特性,验证腰椎间盘退变Pfirrmann分级能否反应髓核组织在细胞水平的退变程度.方法 取术中获得的患者的髓核组织,按腰椎椎间盘退变Pfrrmann分级标准进行分组.组织切片甲苯胺蓝观察比较各组髓核内细胞...
