目的:探究3.0T高场磁共振成像(MRI)对肩袖损伤的诊断准确率、敏感性及特异性,分析肩袖损伤MRI肩部软组织影像,为肩袖损伤的诊断和评估提供可靠影像学依据.方法:选取2020年3月~2022年3月宁德市闽东医院医学影像科接诊的60例疑似肩袖损伤患者作为研究对象,采用3.0T高场磁共振成像诊断,以病理检查结果为金标准,分析MRI诊断肩袖损伤的检测准确率、敏感度及特异度、MRI影像下肩关节损伤分型的一致性行Kappa检验.分析MRI影像下肩袖损伤影像特征,综合分析肩袖损伤的类型、部位和程度.结果:MRI检查准确度为93.33%(56/60)、灵敏度为94.34%(50/53),与金标准一致性很好,Kappa值=0.835、0.830,特异度为85.71%(6/7),与金标准检测特异度一致性较好,Kappa值=0.785;3.0T高场磁共振成像诊断肩袖损伤类型中,其诊断Ⅰ型、Ⅱ型与病理诊断一致性很好,诊断Ⅲ~Ⅴ型与病理诊断一致性较好.肩袖损伤MRI影像分析结果得知,T1加权成像显示肌腱的形态和位置,T2加权成像显示肌腱的水分含量、病变情况及肌腱的撕裂情况.根据肩袖损伤MRI影像可确定肩袖损伤类型,完全撕裂:T1WI低信号强度,T2WI高信号强度,肩袖组织完全断裂,肩袖冈上肌腱部位出现贯穿整个肩袖的全层断裂.部分撕裂:T2WI高信号强度,T1WI现低信号强度,表现在冈上肌腱的同侧面,信号未贯穿全层,肩袖组织出现局部变形、局部水肿.结论:肩袖损伤采用3.0T高场磁共振成像诊断价值高,可准确对肩袖损伤进行分型,通过对肩袖损伤MRI影像周围软组织的观察和分析可以确定肩袖损伤的范围、类型及严重程度,为治疗提供更为精准的参考依据.
Diagnostic Value of 3.0T High Field Magnetic Resonance Imaging in Rotator Cuff Injury
Objective:Exploring the diagnostic accuracy,sensitivity,and specificity of 3.0T high field magnetic resonance imaging(MRI)for rotator cuff injury,analyzing the MRI shoulder soft tissue imaging of rotator cuff injury,and providing reliable imaging basis for the diagnosis and evaluation of rotator cuff injury.Methods:60 suspected patients with rotator cuff injury admitted to the Medical Imaging Department of Mindong Hospital in Ningde City from March 2020 to March 2022 were selected as the research subjects.3.0T high field magnetic resonance imaging was used for diagnosis,and pathological examination results were used as the gold standard.The detection accuracy,sensitivity,and specificity of MRI diagnosis of rotator cuff injury,as well as the consistency of shoulder joint injury classification under MRI imaging,were analyzed and Kappa test was performed.Analyze the imaging characteristics of rotator cuff injury under MRI imaging,and comprehensively analyze the type,location,and degree of rotator cuff injury.Results:The accuracy of MRI examination was 93.33%(56/60),and the sensitivity was 94.34%(50/53),which was consistent with the gold standard.The Kappa values were 0.835 and 0.830,and the specificity was 85.71%(6/7).The consistency with the gold standard was good,with a Kappa value of 0.785;In the diagnosis of rotator cuff injury types using 3.0T high field magnetic resonance imaging,the consistency between the diagnosis of type I and type II and pathological diagnosis is good,and the consistency between the diagnosis of types III-V and pathological diagnosis is good.The MRI imaging analysis of rotator cuff injury revealed that T1 weighted imaging showed the shape and position of the tendon,while T2 weighted imaging showed the moisture content,lesion status,and tear of the tendon.Based on MRI images of rotator cuff injury,the type of rotator cuff injury can be determined.Complete tear:low signal intensity on T1WI,high signal intensity on T2WI,complete rupture of rotator cuff tissue,and full-thickness rupture of the rotator cuff supraspinatus tendon that runs through the entire rotator cuff.Partial tear:High signal intensity on T2WI,low signal intensity on T1WI,manifested on the same side of the supraspinatus tendon,signal not penetrating the entire layer,and local deformation and edema of the rotator cuff tissue.Conclusion:The diagnostic value of using 3.0T high field magnetic resonance imaging for rotator cuff injury is high,and it can accurately classify rotator cuff injury.By observing and analyzing the surrounding soft tissue on MRI images of rotator cuff injury,the scope,type,and severity of rotator cuff injury can be determined,providing more accurate reference basis for treatment.
