研究目的: |
本研究从时间动态角度量化分析股骨头坏死的病情演变规律,主要探究负重区硬化带与坏死区信号强度比值(SIR)对股骨头坏死塌陷发生时间的预测作用,明确其能否作为预测股骨头塌陷的独立影像学指标;同时分析 SIR 与距塌陷发生时间的纵向相关性,探寻塌陷前 SIR 的动态变化趋势及关键时间窗口,构建 4 个月内股骨头塌陷短期风险预测模型,确定 SIR 临床预测最佳截断值,并在校正 JIC 分型等传统预后因素后,进一步验证 SIR 的独立预测价值,为股骨头坏死早期干预及短期塌陷风险预判提供客观影像学依据。 |

Objectives of Study: |
This study quantitatively analyzed the evolution pattern of osteonecrosis of the femoral head from a temporal dynamic perspective. The main objective was to explore the predictive effect of the ratio of signal intensity (SIR) between the hardened zone and the necrotic zone in the weight-bearing area on the time of femoral head collapse, and to clarify whether it could serve as an independent imaging indicator for predicting femoral head collapse. At the same time, the longitudinal correlation between SIR and the time of collapse occurrence was analyzed to explore the dynamic change trend of SIR before collapse and the key time window. A short-term risk prediction model for femoral head collapse within 4 months was constructed, and the optimal cutoff value of SIR for clinical prediction was determined. After correcting for traditional prognostic factors such as JIC classification, the independent predictive value of SIR was further verified to provide objective imaging evidence for early intervention of femoral head necrosis and short-term risk prediction of femoral head collapse. |
