摘　　要：目的　探讨非潜水性骨梗死的X线平片及MRI征象。方法　 6例非潜水性骨梗死病人行MRI及X线平片检查 ,并对X线平片和MRI征象进行对照分析。结果　①病变主要累及股骨下端和胫骨上端且双侧发病。②平片改变主要呈骨质硬化 ,其阳性率约为MR检出率的 5 0 % (9 18) ,确诊率为 16.7% (3 18) ;③MRI征象主要为 :梗死病变中心呈短T1 骨髓信号 ,周边环绕花边状长T1 信号带 ;④MRI可清楚显示邻近关节受累 ,平片难以发现。结论　平片对本病诊断价值有限 ,MRI是本病最好的检查手段 。Objective To investigate the X ray and MRI manifestation of the non diver bone infarction.Method 6 cases of non diver bone infarction were examined by MRI and X ray plain film.Their X ray manifestation were analysed in contrast with MRI manifestation.Result ①It occurred on the low part of femur and the upper part of tibia in both sides.②The main X ray changes were bone sclerosis.The positive ratio was about 1/2 in X ray plain film contrasting MRI and its definite diagnosis ratio was only about 1/6.③The main MRI manifestation were short T 1 signal in the center of the focus of bone infarction and a tortuous border with long T 1 signal around the focus.④Near joints involves were showed by MRI,but X ray plain film could not.Conclusion The diagnosing value of X ray plain film was limited.MRI is the best way to examine and find the non diver bone infarction.It can give you a definite diagnosis and the range this disease involved.
