评价核磁共振技术在股骨头坏死诊断中的价值

To Evaluate the Value of MRI in the Diagnosis of Avascular Necrosis of the Femoral Head

目的对核磁共振技术诊断股骨头坏死的临床价值进行探讨。方法取本院2015年8月份到2016年10月份收治的40例股骨头坏死患者设为研究对象。40例患者依次实施核磁共振技术检查以及CT检查。全程关注患者的诊断工作进展,并进行分析和比较。结果 40例患者经CT检查显示,确诊为股骨头坏死的患者有17例,占42.5%;核磁共振检查显示,确诊为股骨头坏死的患者有36例,占90%。核磁共振组的确诊率较高,与CT组的数据比较差异性明显,证实存在统计学意义,P<0.05。CT检查显示有2例患者为I期,表现为星芒结构增粗明显且变形;II期患者有8例,表现为无明显星芒状结构,存在骨硬化以及囊状透亮区;III期患者有4例,表现为新月征明显,存在轻度骨碎裂以及关节面塌陷;IV期患者有3例,表现为关节面塌陷、畸形,且关节间隙狭窄。结论对股骨头坏死患者实施核磁共振技术,其敏感性更高,相比CT具有更高的诊断率,是股骨头坏死可靠的诊断方法。

Objective The clinical value of nuclear magnetic resonance(NMR)technology in the diagnosis of femoral head necrosis were discussed.Methods From August 2015 to October 2016 were 40 patients with femoral head necrosis were set as the research object.40 patients were checked for nuclear magnetic resonance(NMR)technology and CT examination in turn. Focus on the patient's diagnosis progress,and analyzed and compared.Results 40 cases of patients with CT showed that the diagnosis of osteonecrosis of the femoral head in patients with a total of 17 cases,accounting for 42.5%;magnetic resonance imaging(MRI),the diagnosis of osteonecrosis of the femoral head in patients with a total of 36 cases,accounting for 90%.The diagnosis rate of MRI group was higher,and the difference between P<0.05 group and the CT group was significant.Conclusion The implementation of the nuclear magnetic resonance(NMR)technology in patients with femoral head necrosis,its sensitivity is higher,compared with CT has higher diagnosis rate,is a reliable diagnostic methods femoral head necrosis.
