摘要
目的:观察对比膝关节外伤患者磁共振(MRI)和64排螺旋计算机断层扫描(CT)诊断结果。方法:选取珠海市遵义医学院附属第五医院2014年12月至2016年12月收治的60例膝关节外伤患者作为研究对象,采用数字表法将所有患者简单随机分为观察组和对照组,每组30例。对照组患者采用64排螺旋CT进行诊断,观察组患者采用磁共振弥散加权成像(DWI)的方法进行诊断。同时选取30例本院体检的正常人,并将其骨髓平均值与观察组患者的外伤性骨髓水肿患者、生理反应性骨髓水肿表观弥散系数(ADC)进行比较,并对比两组患者经过不同方式诊断后的确诊率、漏诊率、半月板损伤与韧带损伤评估情况,并观察患者骨挫伤愈合过程中的DWI动态变化特点。结果:诊断后,观察组患者的确诊率为100.00%,无漏诊率,均优于对照组,差异具有统计学意义(P<0.05);且观察组对半月板损伤与韧带损伤评估比较,差异无统计学意义(P>0.05);对照组对半月板损伤与韧带损伤的评估价值更高,与观察组相比具有统计学意义(P<0.05);同时,经DWI检查,患者外伤愈合过程中的DWI动态变化显示,外伤性骨髓水肿患者、生理反应性骨髓水肿患者的ADC值比较,差异具有统计学意义(P<0.05)。结论:在膝关节外伤患者的诊断中,DWI的诊断准确率高于64排螺旋CT,且ADC值对患者的鉴别诊断意义较大。
Objective To observe and compare the knee injury magnetic resonance and 64 slice spiral CT diagnosis.Methods 60 cases of knee joint trauma were selected from December 2014 to December 2016 were the Fifth Affiliated Hospital of Zunyi Medical College,Zhuhai city as the research object,using digital table method,all patients were randomly divided into observation group and control group,30 cases in each group.The control group underwent 64 slice CT diagnosis,observation group were treated by diffusion-weighted magnetic resonance imaging（DWI） diagnostic method.At the same time selected 30 cases of normal physical examination in our hospital,and the average value of bone marrow and bone marrow edema in patients with traumatic observation group of patients,the physiological response of the bone marrow edema ADC values were compared,and compared two groups of patients after different diagnosis after diagnosis rate,misdiagnosis rate,meniscus and ligament injury assessment,DWI and observe the dynamic changes of bone contusion in the healing process.Results after diagnosis,patients in the observation group the diagnosis rate was 100 %,no misdiagnosis rate was better than the control group and the observation group,P〈0.05;for the plate loss No statistically significant differences,injury and ligament damage assessment P〉0.05;control group evaluation of meniscus and ligament injury of higher value,compared with the observation group with statistical significance（P〈0.05）;at the same time,the diffusion weighted magnetic resonance imaging in patients with trauma healing showed diffusion weighted magnetic resonance imaging dynamic changes in the process of traumatic bone marrow edema patients,there are significant differences between the physiological response of bone marrow edema in patients with ADCP〈 0.05.Conclusion in the diagnosis of knee trauma,diagnosis of magnetic resonance diffusion-weighted imaging with high accuracy in the 64 row spiral CT,and the value of ADC in differential diagnosis of patients with
