摘要
目的探讨三维磁共振成像(3DMRI)在前交叉韧带(ACL)损伤分级诊断中的应用。方法回顾性分析我院2015年1月至2017年12月收治的80例因膝关节损伤行MRI检查患者(损伤组)的临床资料,所有患者均行关节镜检查及常规、三维MRI检查。另选取50例健康志愿者作为对照组,均行常规、三维MRI检查。以关节镜结果为金标准,比较常规MRI及三维MRI诊断的灵敏度、特异度、阳(阴)性预测值,对比分析损伤组与对照组的ACL显示结果及诊断结果。结果 80例膝关节损伤患者中,关节镜检查ACL损伤51例,常规MRI检查ACL损伤49例,诊断的灵敏度为0.824,特异度为0.759,三维MRI检查ACL损伤52例,诊断的灵敏度为0.941,特异度为0.862。损伤组80例患者中,常规MRI扫描I级25例,II级18例,III级7例,三维MRI扫描I级75例,II级4例,III级1例,常规MRI扫描ACL完整31例,部分撕裂25例,完全撕裂24例,三维MRI扫描ACL完整28例,部分撕裂28例;健康对照组50例受检者中,常规MRI扫描I级29例,II级21例,三维MRI扫描50例均为I级,两种方法检查均为ACL完整。结论三维磁共振成像可完整显示ACL结构,提高ACL诊断灵敏度及分级准确性。
Objective To explore the application of three-dimensional magnetic resonance imaging(3D-MRI)in grading diagnosis of anterior cruciate ligament(ACL)injury.Methods The clinical data of 80 patients who underwent MRI due to knee joint injury(injury group)from January 2015 to December 2017 in our hospital were retrospectively analyzed.All patients were given arthroscopy and routine and three-dimensional MRI.Another 50 healthy volunteers were selected as control group,and they were given routine and three-dimensional MRI.The arthroscopy results were used as the gold standard,and the sensitivity,specificity and positive(negative)predictive value of routine MRI and three-dimensional MRI were compared.The results of ACL and diagnosis were compared between injury group and control group.Results Among the 80 patients with knee joint injury,51 cases were with ACL injury by arthroscopy and 49 cases were with ACL injury by routine MRI,and the sensitivity and specificity of diagnosis were 0.824 and 0.759,and 52 cases were with ACL injury by three-dimensional MRI,and the sensitivity and specificity of diagnosis were 0.941 and 0.862.Among the 80 patients in injury group,there were 25 cases of grade I,18 cases of grade II and 7 cases of grade III by routine MRI scan,and there were 75 cases of grade I,4 cases of grade II and 1 case of grade III by three-dimensional MRI,and there were 31 cases of complete ACL,25 cases of partial tearing and 24 cases of complete tearing by routine MRI scan,and there were 28 cases of complete ACL and 28 cases of partial tearing by three-dimensional MRI scan.Among 50 subjects in healthy control group,there were 29 cases of grade I and 21 cases of grade II by routine MRI scan,and there were 50 cases of grade I by three-dimensional MRI scan,and the two methods showed complete ACL.Conclusions Three-dimensional magnetic resonance imaging can completely display the ACL structure and improve the sensitivity and grading accuracy of ACL.
