MRI Diagnosis of Occult Fracture in the Bone of the Clinical Value

目的探讨MRI在四肢骨隐性骨折诊断中的临床价值。方法分析2007年4月至2008年10月在我院行MRI检查的60例患者的挫伤病灶部位和MRI表现。结果MRI表现为T1WI像显示隐性骨折区,条状或走行不规则的紊乱低信号,部分病例骨皮质下显示线状低信号带改变,其宽度均<4mm,与T1WI低信号改变相应部位在T2WI亦表现为相应区的低信号,但低信号周围可见高信号水肿改变;患者经MRI确诊后,保守制动治疗6个月,功能恢复正常。结论MRI能够准确发现和早期诊断四肢骨隐性骨折。

Objective To investigate the MRI diagnosis of occult fracture in the bone of clinical value.Methods Analysis of April 2007～2008 year at my house 10 month line MRI examination of 60 cases of contusion in patients with MRI lesions and the performance of the site.Result T1WI showed the results of MRI showed occult fracture zone as,line strips or irregular disorder go low signal,and some cases of cortical bone is shown with linear low-signal changes,and its width is less than 4 mm,with corresponding changes T1WI low signal site at T2WI also showed a corresponding low signal areas, but can be seen around the low-- signal edema high signal changes patients diagnosed by MBI after the brake conservative treatment for 6 months, function returned to normal.Conclusions MRI can accurately detect and early diagnosis of occult fracture of bone.
