Abstract

Background: Currently, dual-energy X-ray absorptiometry (DEXA) and quantitative CT (QCT) are commonly used in clinical practice to measure bone mineral density (BMD), offering diagnostic value but involving radiation and inability to visualize bone microstructure. This study aims to assess lumbar spine bone microstructure changes in normal, osteopenic, and osteoporotic groups using IVIM-DWI and IDEAL-IQ sequences to provide useful information for clinical practice.

Methods: A total of 346 patients (50-87 years, 232 females, 114 males) underwent spinal DEXA and MRI. Based on the BMD obtained from DEXA, the patients were stratified into: normal (n=79), osteopenia (n=92), and OP (n=175) groups. Then to evaluated the results of IVIM-DWI and IDEAL-IQ and extracted quantitative parameters from regions of interest covering the L1 to L4 vertebrae. Group comparisons used One-way analysis of variance and the Kruskal‒Wallis H-test. Receiver operating characteristic (ROC) and Spearman's analyses evaluated diagnostic performance and correlations.

Results: Significant differences existed in the ADCslow, f, FF and R2* between groups (P<0.05). BMD was weakly positively correlated with ADCslow, f, and R2* (r=0.494, 0.153, 0.182, 0.029, P<0.001) but a negative correlation with FF (r=-0.402, P<0.001). BMD and the ADCslow and R2* decreased but FF increased with age (P<0.05 for all), whereas no significant association existed between age and ADCfast or f value (P>0.05). FF had the highest areas under the curve (AUCs) (0.624, 0.831 and 0.747) and sensitivity (72.2%, 70.9% and 81.5%) in differentiating normal from osteopenia patients, normal from osteoporosis patients, and osteopenia from osteoporosis patients, respectively. ADCslow and f had the highest specificity (88%) in differentiating between normal and osteopenia patients, while ADCslow had the highest specificity (91.4%) in differentiating between normal and osteoporosis patients.

Conclusion: Quantitative parameters extracted from IVIM-DWI and IDEAL-IQ have the potential to become good biomarkers for diagnosing OP.

利用IVIM-DWI和IDEAL-IQ序列评估骨质疏松症腰椎微结构。
背景:目前,临床常用双能x线吸收仪(DEXA)和定量CT (QCT)测量骨矿物质密度(BMD),具有诊断价值,但涉及辐射且无法观察骨微观结构。本研究旨在利用IVIM-DWI和IDEAL-IQ序列评估正常、骨质减少和骨质疏松组腰椎骨微观结构的变化,为临床实践提供有用的信息。方法:346例患者(50 ~ 87岁,女性232例,男性114例)行脊柱DEXA和MRI检查。根据DEXA获得的骨密度,将患者分为正常组(n=79)、骨质减少组(n=92)和OP组(n=175)。然后评估IVIM-DWI和IDEAL-IQ的结果,并从L1至L4椎体的感兴趣区域提取定量参数。组间比较采用单向方差分析和Kruskal-Wallis h检验。受试者工作特征(ROC)和Spearman分析评估诊断表现和相关性。结果:各组间ADCslow、f、FF及R2*差异均有统计学意义(P0.05)。FF曲线下面积(auc)最高,分别为0.624、0.831和0.747,对正常与骨质疏松患者、正常与骨质疏松患者、骨质减少与骨质疏松患者的敏感性分别为72.2%、70.9%和81.5%。ADCslow和f区分正常与骨质减少患者的特异性最高(88%),而ADCslow区分正常与骨质疏松患者的特异性最高(91.4%)。结论:从IVIM-DWI和IDEAL-IQ中提取的定量参数有可能成为诊断OP的良好生物标志物。

期刊介绍: Clinical Interventions in Aging, is an online, peer reviewed, open access journal focusing on concise rapid reporting of original research and reviews in aging. Special attention will be given to papers reporting on actual or potential clinical applications leading to improved prevention or treatment of disease or a greater understanding of pathological processes that result from maladaptive changes in the body associated with aging. This journal is directed at a wide array of scientists, engineers, pharmacists, pharmacologists and clinical specialists wishing to maintain an up to date knowledge of this exciting and emerging field.
