MSCT结合MRI对成人腕关节扭伤的影像分析

Imaging Analysis of Wrist Sprain in Adults with MSCT and MRI

腕关节扭伤多为外界暴力引起,一般情况下临床只在患者出现扭伤后进行影像学检查,但由于腕关节的结构复杂,临床尚无法完全精确判断扭伤情况,其诊断标准也存在一定的局限性,这给腕关节扭伤的病情分析造成了一定困难。由于骨骼重叠问题的存在,X线在诊断腕关节扭伤方面的效能不佳,易出现图像失真、误诊漏诊的情况。多层螺旋CT(MSCT)与磁共振成像(MRI)技术均具有强大的后处理功能,可为腕关节扭伤提供准确、直观、全面的影像学信息。但是两种方式单独使用均存在一定的局限性,联合检测可以明显减少误诊、漏诊情况的发生。本文对MRI联合MSCT技术在腕关节扭伤检查中的应用进行综述,并分析联合检测方法的应用价值,为临床提供依据。

The wrist sprain is mostly caused by external violence.Generally,imaging examination is performed only after the sprain occurs in patients.However,due to the complex structure of wrist joint,it is still impossible to completely and accurately judge the sprain in clinical practice,and its diagnostic criteria also have some limitations,which makes it difficult to analyze the condition of wrist sprain.Due to the existence of bone overlap,X-ray is not effective in the diagnosis of wrist sprain,which is prone to image distortion,misdiagnosis and missed diagnosis.Multi slice spiral CT(MSCT)and magnetic resonance imaging(MRI)have powerful post-processing functions,which can provide accurate,intuitive and comprehensive imaging information for wrist sprain.However,there are some limitations in using the two methods alone,and joint detection can significantly reduce the occurrence of misdiagnosis and missed diagnosis.This article reviews the application of MRI combined with MSCT in wrist sprain examination,and analyzes the application value of the combined detection method to provide a basis for clinical practice.
