Background: Osteoporosis is a common, underdiagnosed condition causing increased risk of fracture. While dual-energy X-ray absorptiometry (DXA) is the diagnostic standard, this may not be successfully targeted to individuals at the highest risk. This study presents an extensive nationwide dataset characterizing DXA-scanning practices in Denmark.
Methodology: In this study, we identified all Danish residents from the birth cohort 1900-1960, with a first DXA scan between 2010-2022 to form the Nationwide Osteoporosis Cohort Trials Environment (NOCTE) dataset. These individuals were matched 1:5 to a non-scanned reference population by birth year, sex, and region of residence. Individual data were linked to national registers for comprehensive sociodemographic and clinical information.
Results: The final cohort included 263,651 individuals who underwent DXA scanning. At their first scan, 33% of women and 17% of men had osteoporosis. Compared to the matched reference, the scanned cohort had similar socioeconomic profiles but substantially different clinical profiles. Scanned individuals had a much higher prevalence of prior major osteoporotic fractures, prior systemic glucocorticoid exposure, and overall comorbidity burden.
Conclusion: Referral for DXA in Denmark is driven by clinical risk rather than socioeconomic status, reflecting an equitable resource allocation. However, a significant diagnostic gap persists, as many high-risk individuals with prior fractures did not receive a DXA. The NOCTE cohort is a new, powerful resource for developing strategies to help close this gap.
背景:骨质疏松症是一种常见的未被诊断的疾病,会增加骨折的风险。虽然双能x线吸收仪(DXA)是诊断标准,但它可能无法成功地针对高危人群。本研究提出了一个广泛的全国性数据集,描述了丹麦的dxa扫描实践。方法:在这项研究中,我们从1900-1960年出生队列中确定了所有丹麦居民,并在2010-2022年间进行了第一次DXA扫描,形成了全国骨质疏松症队列试验环境(NOCTE)数据集。根据出生年份、性别和居住地区,这些个体与未扫描的参考人群的匹配比例为1:5。个人数据与国家综合社会人口统计和临床信息登记册相关联。结果:最终队列包括263,651名接受DXA扫描的个体。在第一次扫描时,33%的女性和17%的男性患有骨质疏松症。与匹配的参考相比,扫描队列具有相似的社会经济概况,但临床概况有很大不同。扫描的个体有更高的患病率,既往的主要骨质疏松性骨折,既往的系统性糖皮质激素暴露,以及总体合并症负担。结论:丹麦的DXA转诊是由临床风险而不是社会经济地位驱动的,反映了公平的资源分配。然而,显著的诊断差距仍然存在,因为许多先前骨折的高危患者没有接受DXA。note队列是制定有助于缩小这一差距的战略的一个新的、强大的资源。

A serious worldwide health issue, osteoporosis is characterized by weakened bones and a higher risk of fracture. Though alternative imaging modalities like quantitative ultrasound (QUS), radiographic absorptiometry (RA), quantitative computed tomography (QCT), and radiofrequency echographic multispectrometry (REMS) have emerged as viable diagnostic or screening tools, dual-energy X-ray absorptiometry (DEXA) is still the gold standard for measuring bone mineral density (BMD). The purpose of this systematic review was to evaluate the clinical usefulness, diagnostic accuracy, and dependability of different radiographic modalities for osteoporosis detection. In order to find papers published between 2001 and 2023 comparing DEXA with other radiographic modalities for osteoporosis diagnosis, a thorough search of the PubMed, Scopus, and ScienceDirect databases was undertaken. There were ten studies that qualified. Study design, demographic characteristics, imaging methods, diagnostic thresholds, and performance metrics (sensitivity, specificity, and correlation coefficients) were among the data that were extracted. Across studies, DEXA consistently demonstrated high precision and strong correlation with fracture risk, confirming its role as the reference standard. QUS showed moderate agreement with DEXA, supporting its use as a screening tool but not for diagnostic confirmation. RA provided good reproducibility but lower sensitivity compared with DEXA. QCT exhibited superior sensitivity (up to 91%) and early trabecular bone detection but was limited by higher cost and radiation exposure. Emerging evidence for REMS demonstrated strong correlation with DEXA (r = 0.85–0.90), comparable diagnostic accuracy, and the advantage of being radiation-free and portable. DEXA remains the gold standard for osteoporosis diagnosis; however, QCT and REMS show promising diagnostic accuracy and may complement DEXA for early detection and longitudinal monitoring. QUS and RA can serve as cost-effective screening tools, particularly in settings where DEXA is unavailable. Further large-scale, prospective studies with standardized diagnostic thresholds are needed to validate these findings and optimize imaging strategies for osteoporosis management.
骨质疏松症是一个严重的全球性健康问题,其特点是骨骼变弱和骨折风险较高。虽然定量超声(QUS)、放射吸收仪(RA)、定量计算机断层扫描(QCT)和射频超声多光谱法(REMS)等替代成像方式已经成为可行的诊断或筛查工具,但双能x射线吸收仪(DEXA)仍然是测量骨矿物质密度(BMD)的金标准。本系统综述的目的是评估骨质疏松症不同影像学检查的临床有效性、诊断准确性和可靠性。为了找到2001年至2023年间发表的比较DEXA与其他骨质疏松症放射诊断方式的论文,我们对PubMed、Scopus和ScienceDirect数据库进行了全面的搜索。有10项研究符合条件。提取的数据包括研究设计、人口统计学特征、成像方法、诊断阈值和性能指标(敏感性、特异性和相关系数)。在所有研究中,DEXA始终表现出高精度和与骨折风险的强相关性,证实了其作为参考标准的作用。QUS与DEXA表现出中度一致,支持其作为筛查工具,但不用于诊断确认。RA重复性好,但灵敏度较DEXA低。QCT表现出更高的灵敏度(高达91%)和早期小梁骨检测,但受到较高成本和辐射暴露的限制。新出现的证据表明REMS与DEXA (r = 0.85-0.90)、相当的诊断准确性以及无辐射和便携的优势有很强的相关性。DEXA仍然是骨质疏松症诊断的金标准;然而,QCT和REMS显示出有希望的诊断准确性,可以补充DEXA进行早期检测和纵向监测。QUS和RA可以作为具有成本效益的筛查工具,特别是在没有DEXA的情况下。需要进一步的大规模、具有标准化诊断阈值的前瞻性研究来验证这些发现,并优化骨质疏松症管理的影像学策略。

The relationship between changes in calcium concentration and bone mineral density by anti-bone resorptive therapy 抗骨吸收治疗后钙浓度变化与骨密度的关系。

Background: Hypocalcemia after initiating antiresorptive therapy is well documented, but the association between early changes in serum-corrected calcium (Ca) concentration and long-term bone mineral density (BMD) response in osteoporosis remains unclear. This study compared early Ca changes and BMD outcomes in patients treated with zoledronic acid or denosumab.
Methodology: In this retrospective study, 67 outpatients with osteoporosis received either zoledronic acid (n = 25) or denosumab (n = 42). Baseline BMD, serum-corrected Ca concentration, bone turnover markers, estimated glomerular filtration rate (eGFR), and 25-hydroxyvitamin D [25(OH)D] were recorded. Serum-corrected Ca concentration and eGFR were reassessed at 1 week, 6 months, and 12 months and BMD was measured at baseline, 6 months, and 12 months. To prevent hypocalcemia, patients received different vitamin D regimens according to standard practice (active vitamin D3 for zoledronic acid and combined natural and active vitamin D for denosumab). Multivariate regression has been adjusted for age, baseline BMD, 25(OH)D, eGFR, and TRACP-5b.
Results: A significant decrease in serum-corrected Ca at 1 week was observed in both groups. The magnitude of this decrease was negatively associated with lumbar spine BMD change at 12 months (zoledronic acid: r = −0.59, p = 0.0077; denosumab: r = −0.52, p = 0.0067). This association remained significant after multivariate adjustment. ROC analysis showed that Ca decrease predicted greater BMD gains (AUC 0.909 for zoledronic acid and AUC 0.81 for denosumab), but these results should be interpreted with caution due to the small sample size and different vitamin D regimens.
Conclusions: Early decreases in serum-corrected Ca concentration after antiresorptive therapy were associated with greater BMD gains at 12 months, independent of baseline vitamin D, renal function, and bone turnover markers. This study is exploratory and preliminary in nature, and its findings should be interpreted with caution.
背景:开始抗吸收治疗后的低钙血症有充分的文献记载,但骨质疏松症患者血清校正钙(Ca)浓度的早期变化与长期骨密度(BMD)反应之间的关系尚不清楚。该研究比较了接受唑来膦酸或地诺单抗治疗的患者的早期钙变化和BMD结果。方法:在这项回顾性研究中,67例骨质疏松症门诊患者接受唑来膦酸(n = 25)或地诺单抗(n = 42)治疗。记录基线骨密度、血清校正钙浓度、骨转换标志物、估计肾小球滤过率(eGFR)和25-羟基维生素D [25(OH)D]。在1周、6个月和12个月时重新评估血清校正Ca浓度和eGFR,在基线、6个月和12个月时测量BMD。为了预防低钙血症,患者根据标准惯例接受不同的维生素D方案(唑来膦酸治疗活性维生素D3,地诺单抗治疗天然和活性维生素D联合治疗)。对年龄、基线BMD、25(OH)D、eGFR和TRACP-5b进行了多因素回归校正。结果:两组患者1周时血清校正钙均显著降低。这种下降的幅度与12个月时腰椎骨密度变化呈负相关(唑来膦酸:r = -0.59, p = 0.0077;地诺单抗:r = -0.52, p = 0.0067)。在多变量调整后,这种关联仍然显著。ROC分析显示,钙降低预示着更大的骨密度增加(唑来膦酸的AUC为0.909,地诺单抗的AUC为0.81),但由于样本量小和不同的维生素D方案,这些结果应谨慎解释。结论:抗吸收治疗后血清校正钙浓度的早期降低与12个月时更高的骨密度增加相关,与基线维生素D、肾功能和骨转换标志物无关。本研究是探索性的、初步的,研究结果应谨慎解读。

Osteoporotic hip fracture represents a high social and economic burden in western countries. Pharmacological treatments aim to limit/reverse the loss of bone mineral density (BMD). BMD is monitored through dual energy X-ray absorptiometry (DXA). Biomechanical analysis, through 3D-DXA finite element (FE) femur models, has been shown to potentially improve fracture risk prediction. Yet, the capability of 3D-DXA FE simulations to capture the effects of pharmacological treatments on bone strength remains unexplored. Thus, this study aims to evaluate simulated changes in bone strength in subjects with different osteoporosis treatments using 3D-DXA FE models. A cohort of 155 subjects was used to generate the patient-specific FE models. Osteoporosis treatments included Alendronate (AL, n = 54), Denosumab (DMAB, n = 33), Teriparatide (TPTD, n = 31), and Naïve (NAÏVE, n = 37). Bone was modelled as BMD-dependent elasto-plastic material. Lateral fall was simulated, and bone FE-strength changes from baseline were assessed. Integral FE-strength significantly increased by 3.1% and 4.0% in the AL and DMAB groups, respectively. Trabecular and cortical FE-strength significantly increased by 2.2% and 1.9%, respectively with DMAB. Load-bearing capacity increased in both the cortical and trabecular bone of the femoral neck with DMAB and AL, while it only increased in the trabecular bone with TPTD. 3D-DXA FE analysis might help clinicians to better monitor the effects of pharmacological treatments and potentially improve personalised treatment plans for subjects with osteoporosis.
骨质疏松性髋部骨折在西方国家是一个很高的社会和经济负担。药物治疗的目的是限制/逆转骨密度(BMD)的损失。通过双能x射线吸收仪(DXA)监测骨密度。通过3D-DXA有限元(FE)股骨模型进行生物力学分析,已被证明有可能改善骨折风险预测。然而,3D-DXA FE模拟捕捉药物治疗对骨强度的影响的能力仍未被探索。因此,本研究旨在利用3D-DXA FE模型评估不同骨质疏松治疗受试者骨强度的模拟变化。155名受试者被用于生成患者特异性FE模型。治疗骨质疏松的药物包括阿仑膦酸钠(AL, n = 54)、Denosumab (DMAB, n = 33)、特立帕肽(TPTD, n = 31)和Naïve (NAÏVE, n = 37)。骨被建模为依赖于骨密度的弹塑性材料。模拟侧落,评估骨fe强度从基线的变化。AL组和DMAB组整体fe强度分别显著提高3.1%和4.0%。添加DMAB后,骨小梁和皮质fe强度分别显著提高2.2%和1.9%。DMAB和AL组股骨颈皮质骨和股骨小梁骨的承重能力均有增加,而TPTD组仅股骨小梁骨的承重能力有增加。3D-DXA FE分析可以帮助临床医生更好地监测药物治疗的效果,并有可能改善骨质疏松症患者的个性化治疗计划。

Background: This study aimed to evaluate the performance of DeepXray™ Spina, a software that estimates bone mineral density (BMD) and T-scores from frontal lumbar spine X-ray (FLS-X), in predicting osteoporosis.
Methodology: Patients from a Japanese cohort who underwent both FLS-X and dual-energy X-ray absorptiometry (DXA) using Hologic systems within 30 days at Tohoku University Hospital (May 2014-April 2024) were included. BMD was estimated from FLS-X using DeepXray™ Spina, which was developed using dataset from a Taiwanese Cohort. BMD assessed by DXA (observed BMD) and BMD estimated from FLS-X by DeepXray™ Spina (estimated BMD) were compared using Pearson’s correlation coefficient (PCC) and normalized root mean square error (NRMSE). T-scores were converted to osteoporosis classifications as normal, osteopenia, or osteoporosis following the World Health Organization criteria. Classification performance was evaluated by accuracy, sensitivity, specificity, Cohen’s kappa, and quadratic-weighted Cohen’s kappa.
Results: The correlation between estimated and observed BMD was strong, with a PCC of 0.901 and an NRMSE of 0.070. For osteoporosis classification, the accuracy, sensitivity, specificity, and Cohen’s kappa were as follows: 0.902, 1.000, 0.842, and 0.803 for normal; 0.854, 0.729, 0.924, and 0.673 for osteopenia; 0.951, 0.810, 1.000, and 0.863 for osteoporosis.

Background: Osteoporosis is the most common metabolic bone disease in the elderly. This study aimed to assess whether routine T1-weighted MR images can visually indicate the presence of osteoporosis by estimating vertebral bone marrow fat content.
Methods: Lumbar spine MRI and DEXA scans from 320 patients (performed within a 6-month interval) were retrospectively reviewed. Two radiologists independently graded the percentage of high T1 signal within the L4 vertebral body into <50 % or ≥50 %, representing marrow fat content. Visual fat scores were compared with T-scores from DEXA scans. Inter-reader agreement was assessed using Cohen's and Fleiss' kappa statistics. Spearman’s correlation was used to evaluate the association between MRI grading and DEXA scores.
Results: Of the 320 patients (mean age 56.8 years; 80.3 % female), 48.4 % had osteopenia or osteoporosis. Visual MRI grading yielded 141 patients with <50 % and 179 with ≥50 % marrow fat. A weak but statistically significant correlation was observed between MRI visual fat scores and DEXA T-scores (ρ = 0.139, p = 0.013). Inter-reader agreement was moderate (Cohen’s kappa = 0.509, 95 % CI: 0.415 to 0.603).
Conclusion: Routine T1-weighted lumbar spine MRI may serve as an opportunistic screening tool for osteoporosis. Visual estimation of vertebral marrow fat content shows potential to identify patients who may benefit from further DEXA evaluation.
背景:骨质疏松症是老年人最常见的代谢性骨病。本研究旨在评估常规t1加权MR图像是否可以通过估计椎体骨髓脂肪含量来直观地显示骨质疏松症的存在。方法:回顾性分析320例患者的腰椎MRI和DEXA扫描(间隔6个月)。两名放射科医师独立将L4椎体内高T1信号的百分比分为<; 50%或≥50%,代表骨髓脂肪含量。将视觉脂肪评分与DEXA扫描的t评分进行比较。使用Cohen和Fleiss的kappa统计来评估读者间的一致性。Spearman相关用于评估MRI分级与DEXA评分之间的关系。结果:320例患者(平均年龄56.8岁,80.3%为女性)中,48.4%有骨质减少或骨质疏松症。视觉MRI分级显示141例患者骨髓脂肪含量为50%,179例患者骨髓脂肪含量≥50%。MRI视觉脂肪评分与DEXA t评分之间存在微弱但有统计学意义的相关性(ρ = 0.139, p = 0.013)。读者间一致性中等(Cohen’s kappa = 0.509, 95% CI: 0.415 ~ 0.603)。结论:常规t1加权腰椎MRI可作为骨质疏松症的机会性筛查工具。椎骨骨髓脂肪含量的目视估计显示了识别可能从进一步DEXA评估中受益的患者的潜力。

Introduction: Hypertension (HT) and osteoporosis (OP) are common chronic diseases that often coexist in postmenopausal women. This study aimed to investigate the association between the use of antihypertensive medications and the presence of OP.
Methods: We retrospectively analyzed the medical records of 4166 postmenopausal women. Demographic data, age, weight, height, comorbidities, medications and bone mineral density values were collected for all patients screened/followed for OP between 2023 and 2024.
Results: Out of 4166 postmenopausal women, 1659 (39.8 %) were diagnosed with OP. After adjusting for potential confounders using binary logistic regression, diabetes mellitus [OR=0.785 (95 % CI=0.667-0.925) p = 0.004] and hyperlipidemia [OR=0.826 (95 % CI=0.698-0.978) p = 0.026] were negatively associated with OP. Among the antihypertensive medications (N = 2144); furosemide use [OR=1.918 (95 % CI=1.157-3.182) p = 0.012] was positively associated with OP, while thiazide use showed a negative association [OR=0.769 (95 % CI=0.619-0.954) p = 0.017].
Conclusions: Thiazide use was associated with a lower likelihood of OP, while furosemide use was linked to increased odds (about 1.9 times). Further research with larger samples and stratified analyses of antihypertensive classes is warranted to better understand these associations.
高血压(HT)和骨质疏松症(OP)是绝经后妇女常见的慢性疾病。本研究旨在探讨降压药的使用与op的关系。方法:回顾性分析4166例绝经后妇女的医疗记录。收集2023年至2024年间所有OP筛查/随访患者的人口统计学数据、年龄、体重、身高、合并症、药物和骨密度值。结果:在4166名绝经后妇女中,1659名(39.8%)被诊断为op。使用二元logistic回归校正潜在混杂因素后,糖尿病[OR=0.785 (95% CI=0.667-0.925) p = 0.004]和高脂血症[OR=0.826 (95% CI=0.698-0.978) p = 0.026]与op呈负相关。降压药物(N = 2144);速尿使用与OP呈正相关[OR=1.918 (95% CI=1.157 ~ 3.182) p = 0.012],噻嗪类药物使用与OP呈负相关[OR=0.769 (95% CI=0.619 ~ 0.954) p = 0.017]。结论:噻嗪类药物的使用与OP的可能性降低有关,而速尿的使用与OP的可能性增加有关(约1.9倍)。为了更好地了解这些关联,有必要进一步研究更大的样本和降压药类别的分层分析。

Introduction: This study compared the three-dimensional (3D) bone structure based on bone erosion in postmenopausal patients with rheumatoid arthritis (RA) using a novel dual-energy X-ray absorptiometry (DXA)-based 3D analysis tool.
Methods: In this cross-sectional study, 171 postmenopausal women with RA (aged ≥ 50 years) were categorized based on bone erosions on hand and foot X-rays. We conducted 3D bone structure analyses on DXA hip scans using 3D-Shaper software, measuring volumetric BMD of integral (IvBMD), trabecular (TvBMD), and cortical (CvBMD) compartments.
Results: The study included 94 patients without erosion and 77 with erosion. The erosion-positive group showed significantly lower femoral neck (FN) parameters: areal BMD (0.722 ± 0.090 vs. 0.756 ± 0.102 g/cm², p = 0.023), IvBMD (269.784 ± 49.306 vs. 288.610 ± 59.220 mg/cm³, p = 0.027), TvBMD (157.043 ± 39.154 vs. 170.787 ± 45.168 mg/cm³, p = 0.037), and CvBMD (709.563 ± 68.028 vs. 735.182 ± 81.470 mg/cm³, p = 0.026). Multiple regression analysis revealed that disease activity score (DAS28) was independently associated with FN CvBMD (β = -24.693, p = 0.023).
Conclusions: This study demonstrated that bone erosion in RA is associated with significant alterations in bone structure, particularly in the FN region. Disease activity primarily affects cortical bone, highlighting the need for stringent disease management to maintain bone health in patients with RA.
摘要:本研究采用一种新型双能x线吸收仪(DXA)为基础的三维分析工具,比较绝经后类风湿关节炎(RA)患者骨侵蚀的三维(3D)骨结构。方法:在这项横断面研究中,171名绝经后RA患者(年龄≥50岁)根据手部和足部x光片的骨侵蚀情况进行分类。我们使用3D- shaper软件对DXA髋关节扫描进行了三维骨结构分析,测量了整体(IvBMD)、小梁(TvBMD)和皮质(CvBMD)隔室的体积骨密度。结果:无糜烂患者94例,糜烂患者77例。侵蚀阳性组股骨颈FN参数显著降低:面积骨密度(0.722±0.090比0.756±0.102 g/cm²,p = 0.023)、IvBMD(269.784±49.306比288.610±59.220 mg/cm³,p = 0.027)、TvBMD(157.043±39.154比170.787±45.168 mg/cm³,p = 0.037)、CvBMD(709.563±68.028比735.182±81.470 mg/cm³,p = 0.026)。多元回归分析显示,疾病活动评分(DAS28)与FN CvBMD独立相关(β = -24.693, p = 0.023)。结论:本研究表明,RA的骨侵蚀与骨结构的显著改变有关,特别是在FN区域。疾病活动主要影响皮质骨,强调需要严格的疾病管理来维持RA患者的骨骼健康。
