| 目的 探讨高场磁共振(MRI)对骨挫伤的诊断价值.方法 回顾性分析35例骨挫伤患者X线平片、CT及高场强(1.5T)MRI检查资料,并比较各常用MRI序列的信号强度和特点.结果 本组35例X线平片均未见骨折征象,CT检查亦无明显骨折征象,仅见周围软组织肿胀和关节腔积液,高场强MRI检查,SE序列T1WI表现为不规则斑片状、地图状及长条状低信号,T2WI表现为不规则高信号(12例)、等信号(6例)、低信号(17例);质子加权预饱和脂肪抑制(PDW-FS)序列均表现为明显高信号;所有病例都有不同程度软组织损伤和关节腔积液.结论 在X线平片、CT及MRI三种影像检查方法中,MRI是能有效诊断骨挫伤的检查方法.在高场MRI检查的各常用序列中,PDW-FS序列是明确诊断的最佳序列. |

| Objective To investigate the diagnostic value of high field strength MRI in bone contusion. Methods Imaging data of X-ray,CT and MRI of 35 cases with bone contusion were analyzed retrospectively.The signal intension and features of different routine MRI pulse sequences were compared. Results No fracture of all patients was found on plain film.CT scanning showed there were only surrounding soft tissue swelling and liquid of articular capsule, and no obvious fracture.MRI findings with SE sequence were irregul... |
