目的:研究64层CT及MRI诊断隐匿性骨折的临床效果。方法:选取60例隐匿性骨折患者的64层CT及MRI进行分析。结果:50例患者采用64层CT后出现骨皮质或骨小梁中断。17例患者MRT1W1有松质骨内条状低信号带;MRT2W1表明骨折线四周有片状高信号水肿的患者是30例;3例MRT1W1没有出现低信号带,64层CT表明骨皮质中断。结论:64层CT在骨皮质细微骨折方面的诊断效果比MRI好,所以,在临床诊断中,可把64层CT作为隐匿性骨折的首选技术,如果检查结果不够明朗,可以再采用MRI技术进一步诊断,两者结合效果非常好。
Objective: To study the clinical effect of 64-slice CT and MRI in diagnosis of occult fracture. Methods: Sixty cases of occult fracture were selected and analyzed by 64-slice CT and MRI. RESULTS: Cortical or trabecular separation was observed in 50 patients after 64-slice CT. MRT2W1 showed that there were 30 cases with patchy high signal edema around the fracture line. No MRS1W1 low signal band was found in 3 cases, and the cortical bone was disrupted by 64-slice CT in 17 cases. Conclusion: 64-slice CT is more effective than MRI in the diagnosis of cortical bone fractures. Therefore, 64-slice CT can be used as the first choice of occult fracture in clinical diagnosis. If the result of the examination is not clear enough, MRI can be used further Diagnosis, combined with the effect is very good.
