摘要 目的探究磁共振三维技术在距骨损伤评估中的应用情况,并对其价值进行分析。方法选取我院2011年1月-2014年1月收治的26例距骨损伤患者,所有患者均经穿刺活检或手术病理检查确诊为距骨损伤。分别对患者实施关节镜检查与MRI检查,观察检查结果并分析影像学特征。使用磁共振三维技术对距骨损伤进行评估。结果经活检发现内侧病灶左右径、前后径、深度均无显著性差异(P>0.05)。以穿刺活检或手术病理检测为金标准,发现MRI诊断距骨损伤的灵敏度为90.0%(20/23),特异度为95.7%(22/23),准确度为91.3%(42/46),与关节镜诊断的灵敏度95.7%(22/23),特异度95.7%(22/23),准确度95.7%(44/46),无明显差异(P>0.05)。三组序列图像质量进行对比,结果显示,t2-3D-space-fs序列图像比t2-2D-pd-fs-sag更加清晰,t2-3Dspace-fs图像最为清晰,易于对病情进行诊断。结论磁共振三维技术中t2-3Dspace-fs序列扫描对于距骨损伤的评估具有十分明显的临床应用价值,所得影像具有明显的影像学特征,图像清晰,对于距骨损伤的诊断与伤情评估具有重要的指导意义。 Objective To explore and analyze the application value of MRI 3D technology in talus damage assessment.Methods Choose 26 talus damage patients who were admitted in our hospital from January 2011 to January 2014, all patients were confirmed talus damage by biopsy or surgical pathology examination. Respectively for patients with arthroscopy and MRI, observe results and analyze the characteristics of images. Use MRI 3D technology to evaluate talus damage.Results There's no significant difference in the left-right diameter of the inside focus, the anteroposterior diameter of inside focus or depth of inside focus (P〉0.05). By biopsy or surgical pathology examination as gold standard, we found that the sensitivity of MRI diagnosis was 90.0%(20/23), the specificity was 95.7%(22/23), the accuracy was 91.3%(42/46); the sensitivity of arthroscopy diagnosis was 95.7%(22/23), the specificity was 95.7%(22/23), the accuracy was 95.7%(44/46), there's no significant difference in them (P〉0.05). Comparing sequence image quality of three groups , the results showed that T2-3D-space-fs sequence images were more clear than T2-2D-space-fs sequence images, T2-3D-space-fs sequence images were clearest, which would diagnose talus damage easily.Conclusion T2-3D-space-fs sequence of MRI 3D Technology has a significant clinical application value in talus damage assessment, the images have obvious imaging characteristics, they are clear, which has an important value in the diagnosis and injury assessment of talus damage.
