摘　　要：目的探讨pd_tse_spair脂肪抑制和t2_me2d水激发序列在膝关节骨挫伤的临床应用价值。方法回顾性分析膝关节骨挫伤的临床资料和MRI图像,对骨挫伤序列检出能力进行分析,比较同一病灶在不同序列中标准信号强度。结果 pdtse-spair脂肪抑制和t2-me2d水激发序列是检出膝关节骨挫伤的敏感序列,pd_tse_spair脂肪抑制在骨挫伤、半月板损伤、韧带损伤的标准信号强度优于t2_me2d水激发序列,特别在骨挫伤的比较中,差异有统计学意义(P<0.05),可作为临床膝关节骨挫伤的首选检查序列。t2_me2d水激发序列在软骨损伤的标准信号强度优于pd_tse_spair脂肪抑制序列,差异有统计学意义(P<0.05)。结论 MRI脂肪抑制与水激发序列检出膝关节骨挫伤及附属结构病灶非常敏感,能清楚显示损伤部位及病理改变。Objective To explore the clinical application value of pd_tse_spair fat suppression and t2_me2d water excitation sequences in knee joint bone contusion. Methods The clinical data and MRI images of the knee joint bone contusion were analyzed retrospectively, and the bone contusion sequence detection ability was analyzed, and the standard signal intensities of the same lesion in different sequences were compared. Results pd_tse_spair fat suppression and t2-me2d water excitation sequences are sensitive sequences for the detection of the knee joint bone contusion. The standard signal intensity of pd_tse_spair fat suppression is superior to that of t2-me2d water excitation sequences in bone contusion, meniscus injuries, ligament injury, especially the difference in bone contusion between the two was statistically significant（P〈0.05）, and which can be used as the first choice of examination sequence for the clinical knee joint bone contusion. The standard signal intensity of t2_me2d water excitation sequence was superior to that of pd_tse_spair fat suppression sequence, the difference between the two was statistically significant （P〈0.05）. Conclusion MRI pd_tse_spair fat suppression and t2_me2d water excitation sequences are sensitive in the detection of the knee joint bone contusion and attached structures of lesions, which can clearly show the site of injury and pathological changes.
