摘要:

目的 探讨3.0 T磁共振(MRI)T2 mapping序列联合血清新饱食分子蛋白1(nesfatin-1)水平对老年膝关节早期骨关节炎(OA)的诊断价值。 方法 选取2023年5月至2024年5月医院收治的膝关节OA的97例老年患者(OA组)和52例同期老年体检者(对照组),根据X线结果将膝关节OA组分为早期组和非早期组,均接受3.0T MRI T2 mapping序列扫描检测膝关节软骨区域T2值,检测血清nesfatin-1水平,比较上述指标差异并采用ROC曲线分析其对老年膝关节早期OA的诊断价值。 结果 97例老年膝关节OA患者中,早期组35例,非早期组62例,OA组患者膝关节5个软骨区域的T2值及nesfatin-1血清均高于对照组( P < 0.05),早期组均低于非早期组( P < 0.05);膝关节软骨区域T2值和血清nesfatin-1水平单独诊断早期OA的AUC在0.774 ~ 0.871范围,联合诊断的AUC为0.939。 结论 3.0 T磁共振T2 mapping序列联合血清nesfatin-1水平检测对老年膝关节早期OA具有较高的诊断价值。

Abstract:

Objective To investigate the diagnostic potential of combining 3.0T magnetic resonance imaging (MRI) T2 mapping sequences with serum nesfatin-1 levels for detecting early osteoarthritis (OA) in elderly knees. Methods 97 elderly patients with knee osteoarthritis (OA group) and 52 elderly individuals undergoing physical examinations (control group) were recruited from a hospital between May 2023 and May 2024. Based on X-ray findings, the OA group was further divided into an early-stage subgroup and a non-early-stage subgroup. All participants underwent 3.0T MRI T2 mapping sequence scans to measure the T2 values in the knee cartilage region, and serum nesfatin-1 levels were assessed. Differences in these indicators were compared between groups. Additionally, a receiver operating characteristic (ROC) curve was constructed to evaluate the diagnostic value of these parameters for early-stage knee OA in elderly individuals. Results Among 97 elderly patients with knee OA, 35 cases were classified into the early-stage group, and 62 cases were categorized into the non-early-stage group. The T2 values in five cartilage regions of the knee and serum nesfatin-1 levels were significantly higher in the OA group compared to the control group ( P < 0.05). Moreover, these values were significantly lower in the early-stage group than in the non-early-stage group ( P < 0.05). The areas under the curve (AUC) for diagnosing early-stage OA using T2 values in knee cartilage regions and serum nesfatin-1 levels ranged from 0.774 to 0.871. Notably, the AUC for combined diagnosis reached 0.939 ( P < 0.05). Conclusion 3.0T MRI using the T2 mapping sequence in combination with serum nesfatin-1 level detection demonstrates high diagnostic value for early OA in elderly patients with knee involvement.
