腕关节损伤的影像学特征及CT与MRI联合诊断的准确性分析

Imaging Features of Wrist Injury and the Accuracy of Combined CT and MRI Diagnosis

目的探讨腕关节损伤的影像学特征,并对CT联合MRI的诊断价值进行分析。方法纳入40例腕关节损伤患者,2018年1月至2022年1月就诊,所有患者均行CT检查和MRI检查,对比单独检查和联合诊断方式的疾病诊断价值。结果单独CT与单独MRI对腕关节骨折、腕关节脱位和隐匿性骨折的检出率对比无差异(P>0.05),与CT检查比较,MRI对骨挫伤和软骨损伤的检出率更高,对移位骨折片的检出率更低,数据对比有差异(P<0.05);CT联合MRI对腕关节骨折、腕关节脱位、隐匿性骨折、骨挫伤、软骨损伤和移位骨折片的检出率明显高于单一诊断方式(P<0.05)。结论腕关节损伤CT与MRI表现各不相同,联合应用两种方式,可对不同类型腕关节损伤予以准确诊断。

Objective To investigate the imaging features of wrist injury and to analyze the diagnostic value of CT combined with MRI.Methods A total of 40 patients with wrist joint injury were included,and they were treated from January 2018 to January 2022.All patients underwent CT and MRI examinations to compare the diagnostic value of single examination and combined diagnosis.Results There was no difference in the detection rate of wrist fracture,wrist dislocation and occult fracture between CT alone and MRI alone(P>0.05).Compared with CT examination,MRI had higher detection rate of bone contusion and cartilage injury.The detection rate of displaced fracture fragments was lower,and the data comparison was different(P<0.05).The incidence rate was significantly higher than that of single diagnosis method(P<0.05).Conclusion CT and MRI manifestations of wrist injury are different.The combined application of the two methods can accurately diagnose different types of wrist injury.
