来源:用户上传      作者:曾志强

  【摘要】目的:探讨股骨头坏死患者CT与核磁共振的临床诊断价值。方法:选取2020年1月至2021年12月来本院就诊的股骨头坏死患者78例作为研究对象,按照诊断方法分成观察组(n=39例)和对照组(n=39例),对照组采用CT扫描技术诊断,观察组采用核磁共振(MRI)扫描技术诊断,将病理诊断结果作为探究金标准,并将两种检查方法结果进行对比分析。结果:临床诊断后,观察组诊断准确率(94.87%)显著高于对照组(74.36%)(P<0.05),且观察组对Ⅰ期、Ⅱ期、Ⅲ期、Ⅳ期诊断符合率(81.82%、83.33%、87.50%、100.00%)均高于对照组(53.85%、66.67%、66.67%、50.00%)(P<0.05)。结论:对于股骨头坏死患者,临床采取核磁共振检查效果优于CT检查,检出率较高,有助于后期进行针对性治疗,值得推广。

  【Abstract】Objective:To explore the clinical diagnostic value of CT and MRI in patients with femoral head necrosis.Methods:78 patients with femoral head necrosis treated in the hospital from January 2020 to December 2021 were selected as the research objects.According to the diagnostic methods,they were divided into the observation group (n=39) and the control group (n=39).The control group was diagnosed by CT technology,and the observation group was diagnosed by magnetic resonance (MRI).The pathological diagnosis results were taken as the gold standard for exploration,and the test results of the two methods were compared and analyzed.Results:After clinical diagnosis,the diagnostic accuracy of the observation group (94.87%) was significantly higher than that of the control group (74.36%) (P<0.05),and the diagnostic coincidence rate of stage Ⅰ,Ⅱ,Ⅲ and Ⅳ in the observation group (81.82%,83.33%,87.50%,100.00%) was higher than that in the control group (53.85%,66.67%,66.67%,50.00%) (P<0.05).Conclusion:For patients with femoral head necrosis,the clinical detection effect of MRI test is better than that of CT examination,which is helpful for the later targeted treatment and is worth popularizing.

  股骨头坏死又被称为股骨头无菌性坏死以及股骨头缺血性坏死,该类疾病由多种因素导致股骨头内部血液供应不足演变成为骨细胞坏死现象,致病原因尚不明确,但该类疾病发病率呈增高趋势,且发病年龄范围逐渐年轻化[1]。该病若得不到及时治疗会增加后期致残率,严重影响病人的日常生活质量。日常酗酒或长期使用大量激素或髋关节外伤等均可能造成股骨头坏死现象。随着病情的不断加重,股骨头内部结构会发生改变及出现髋关节退行性骨关节病,关节功能降低,多数患者还会出现股骨疼痛、跛行、行走困难以及关节活动度减少等症状[2-4]。股骨头坏死产生的病理变化虽会影患者髋关节的生理功能,但变化范围有限,通常仅对个别关节造成影响,若临床能早期发现、及时诊断并治疗,能有效延缓病情发展及改善临床症状,促进股骨头痊愈[5]。目前针对股骨头坏死的影像诊断方法主要包括CT扫描及核磁共振检查等技术,由于技术差异,这两种方法各具其自身特点及优势。本研究以股骨头坏死患者作为对象,尝试比较分析CT扫描技术与核磁共振技术在股骨头坏死诊断中的价值及效果差异,具体报告如下。
  1对象与方法
  1.1研究对象
  选取2020年1月至2021年12月本院就诊的股骨头坏死患者78例,按照诊断方法分成观察组(n=39例)和对照组(n=39例),对照组采用CT技术诊断,观察组采用核磁共振(MRI)\断,将病理诊断结果作为探究金标准。对照组患者中男22例,女17例,年龄34~72(59.35±2.35)岁;病程8个月~9年(4.65±1.23)年,Ⅰ期11例,Ⅱ期18例,Ⅲ期8例,Ⅳ期2例,发病原因:髋关节外伤15例,大量激素药物服用9例,其他原因15例。观察组患者中男21例,女18例,年龄32~74(59.38±2.96)岁;病程10个月~10年(4.58±1.51)年,Ⅰ期13例,Ⅱ期18例,Ⅲ期6例,Ⅳ期2例,发病原因:髋关节外伤16例,大量激素药物服用10例,其他原因13例。两组患者临床资料相比均无明显的差异(P>0.05),因此可进行对比研究。
