Background: Many studies have explored the application of the magnetic resonance imaging (MRI)-based vertebral bone quality (VBQ) score as a tool for opportunistic osteoporosis screening before spine surgery. We aimed to conduct a systematic review and meta-analysis of studies to determine the diagnostic value of the VBQ score for bone mineral density (BMD) assessment.

Methods: The PubMed, EBSCO, Ovid, Web of Science, Cochrane Library, Wanfang, China National Knowledge Infrastructure, Chinese Science and Technology Periodical databases were searched to retrieve original studies on VBQ and BMD published from inception to 31 December 2023 with no restrictions on language and the reference standard of BMD. The quality of the included articles was assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2). Summary accuracy metrics were obtained by bivariate random-effects meta-analysis. The area under the curve (AUC) of the summary receiver operating characteristic (SROC) analysis was used to evaluate the performance of the VBQ score. Meta-regression and subgroup analyses were performed to examine the source of heterogeneity.

Results: In total, 23 studies, comprising 2981 patients, from 2022 to 2023, of high- or medium-to-high scientific quality were included in the meta-analysis. The pooled sensitivity, specificity, and diagnostic odds ratio (DOR) of the VBQ score in the assessment of BMD were 0.77 [95% confidence interval (CI), 0.73-0.81; P<0.001], 0.65 (95% CI, 0.59-0.71; P<0.001), and 6.49 (95% CI, 4.82-8.73; P<0.001), respectively, with an area under the SROC curve of 0.78 (95% CI, 0.74-0.82; P<0.001). The presence of heterogeneity was found to have a significant association with factors such as the reference standard, sex, mean age, region of publication, VBQ method, and magnet field strength.

Conclusions: The MRI-based VBQ score has some diagnostic value in detecting osteoporosis. The VBQ score could be used as a tool for opportunistic osteoporosis screening before spine surgery.

Objective: The incidence of vertebral fragile fractures peaked among the elderly population, and identifying individuals at high risk of vertebral fractures and promptly instituting preventions are of critical importance. This study aims to determine the efficacy and values of Hounsfield unit (HU) values, vertebral bone quality (VBQ) scores, bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA), and quantitative computed tomography (QCT) to discriminate between patients with and without vertebral fractures.

Methods: A thorough search was conducted across PubMed, EMBASE, Cochrane Library, Web of Science, CNKI, and Wan Fang Database to identify potential studies that met the eligibility criteria.

Background Context: As lumbar degenerative diseases become more prevalent in an aging population, there is an increasing demand for surgical interventions, such as posterior lumbar interbody fusion (PLIF). However, cage subsidence (CS), observed in 23.9-54% of cases postoperatively, remains a significant complication.

Background: Residual back pain (RBP) is one of the complications following percutaneous vertebroplasty (PVP) in older people with osteoporotic vertebral compression fractures (OVCFs). The vertebral bone quality (VBQ) score obtained from magnetic resonance imaging (MRI) can be used to evaluate bone quality. The objective of this study aimed to explore the potential relationship between the VBQ score and RBP after PVP.

Bone Density of Vertebral Bodies and Ossified Masses in Cervical Ossification of the Posterior Longitudinal Ligament: An Imaging Study Based on MRI, CT, and DEXA.

Calcif Tissue Int

December 2024

Spine Center, Department of Orthopaedics, Shanghai Changzheng Hospital, Second Affiliated Hospital of Naval Medical University, No. 415 Fengyang Road, Huangpu District, Shanghai, 200003, China.

Complications from anterior decompression fusion for cervical ossification of the posterior longitudinal ligament (OPLL) are often related to the bone mineral density (BMD) of vertebral bodies and ossified masses. The aim of this study was to clarify whether dual-energy X-ray absorptiometry (DEXA) T-scores reliably predict BMD in these structures, and whether vertebral bone quality (VBQ) and Hounsfield units (HU) can be effectively used to screen for osteopenia and osteoporosis. A total of 122 patients with cervical OPLL and 105 non-OPLL patients were included.

Objective: To evaluate the modified vertebral bone quality (VBQ) method on the magnetic resonance imaging (MRI) T1-weighted (T1w), T2-weighted (T2w), and fat suppression (FS) series in evaluating bone mineral density (BMD) for patients with degenerative lumbar disease.

Methods: We reviewed preoperative data of postmenopausal female patients aged ≥ 50 years hospitalized to undergo lumbar surgery for degenerative lumbar disease with available MRI and dual-energy X-ray absorptiometry (DEXA). Patients were categorized into three groups according to T-score.
