摘要:
目的：分析磁共振脂肪抑制质子密度加权（PDWI-FS）序列诊断骨关节外伤性骨髓水肿（BME）的价值。方法：选取150例骨关节外伤患者为研究对象，均行矢状位PDWI-FS序列扫描及MRI常规序列扫描，比较两种方法对BME的检出情况、信号强度、图像质量、病灶信噪比及对比噪声比。结果：两种检查方法均显示150例骨关节外伤患者中134例存在225处BME征象，以膝关节外伤患者中多见。PDWI-FS序列显示病灶信号强度主要为3级，占比97.78%（220/225），MRI常规序列显示主要为2级，占比43.11%（97/225），且两种检查方法显示不同强度存在统计学差异（Z=15.919，P<0.05）。PDWI-FS序列显示病灶清晰程度、空间分辨力、图像变形及诊断信心评分［（4.09±0.45）分、（3.65±0.42）分、（3.25±0.37）分、（4.21±0.38）分］均高于常规序列［（3.88±0.39）分、（3.41±0.36）分、（3.14±0.35）分、（3.97±0.34）分］，且差异均有统计学意义（t=4.319，t=5.314，t=2.645，t=5.765；P<0.05）。PDWI-FS序列显示病灶信噪比及周围组织对比噪声比［（2.07±0.23）、（5.52±0.64）］均大于常规序列［（2.01±0.22）、（5.17±0.59）］，且差异有统计学意义（t=2.309，t=4.925；P<0.05）。结论：较MRI常规序列而言，磁共振PDWI-FS序列能有效提高图像质量和病变显示效果，可为骨关节外伤性BME的诊断提供更准确的诊疗信息。
Abstract:
Abstract: Objective To analyze the value of magnetic resonance proton density-weighted fat-saturated (PDWI-FS) sequence in the diagnosis of bone marrow edema (BME) in osteoarticular injury. Methods A total of 150 patients with bone and joint trauma were enrolled in the study. All patients underwent sagittal PDWI-FS sequence scan and conventional MRI sequence scan. The BME detection, signal intensity, image quality, and the signal-to-noise ratio and contrast-to-noise ratio of the lesions were compared between two methods. Results Both methods revealed that there were 225 sites of BME signs in 134 out of the 150 patients, with a higher prevalence in knee joint trauma patients. The signal intensity of the lesions was mainly grade 3 on PDWI-FS sequence and grade 2 on conventional MRI sequence, accounting for 97.78% (220/225) and 43.11% (97/225), indicating that the two methods graded signal intensity differently (Z=15.919, P<0.05). PDWI-FS sequence and conventional sequence had scores of 4.09±0.45 vs 3.88±0.39, 3.65±0.42 vs 3.41±0.36, 3.25±0.37 vs 3.14±0.35 and 4.21±0.38 vs 3.97±0.34 on lesion clarity, spatial resolution, anamorphosis and diagnostic confidence, and the former scored higher (t=4.319, 5.314, 2.645, 5.765 P<0.05). The signal-to-noise ratio and contrast-to-noise ratio of the lesions on PDWI-FS sequence were 2.07±0.23 and 5.52±0.64, higher than 2.01±0.22 and 5.17±0.59 on conventional sequence, and the differences were statistically significant (t=2.309, 4.925 P<0.05). Conclusion Compared with conventional MRI sequence, magnetic resonance PDWI-FS sequence can effectively enhance image quality and display lesions more clearly, providing more accurate information for the diagnosis of BME in osteoarticular injury.
