Abstract

Background: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy that occurs when the median nerve is compressed within the carpal tunnel. Electromyography (EMG) is accepted as the most frequently used and important diagnostic method for CTS. Recently, magnetic resonance imaging (MRI) has begun to be used in CTS patients to directly visualize the median nerve and examine the changes occurring in the nerve structure.

Objectives: In this study, the area of the median nerve was measured at various levels in the wrist in patients with CTS using MRI, examining its relationship with signal increase, and comparing this to results obtained with EMG.

Material and methods: Overall, 35 patients diagnosed with CTS were included in the study. Patients with normal-mild and moderate-severe EMG tests were included in the study; wrist MRI was taken to investigate the area/mm2 of the median nerve at various levels and whether there was an increase in signal. Thenar muscles included in the imaging were also evaluated.

Results: Of the 35 patients included in the study, 24 were women (68.6%) and 11 were men (31.4%). Measurements of the average median nerve area measured in mm2 at the distal radioulnar junction (DRUJ) and the median nerve area measured in mm2 at the hamate bone level were obtained, showing that DRUJ and hamate bone distance measurements were higher in patients with positive EMG. Electromyography findings were also significantly positive in patients with increased signal.

Conclusions: In some cases, the diagnosis of CTS can be easily made with history and physical examination or employing confirmatory tests such as EMG, which is considered the gold standard. Magnetic resonsnace imaging can be used as an alternative method for imaging the median nerve in patients with CTS. In our study, EMG findings were also significantly positive in patients with increased signal on MRI, making it a preferable method, especially in soft tissue-related pathological cases.

比较核磁共振成像和肌电图对确诊腕管综合征患者正中神经面积的测量。
背景:腕管综合征(CTS)是正中神经在腕管内受压时发生的最常见的卡压性神经病。肌电图(EMG)是公认的最常用、最重要的 CTS 诊断方法。最近,磁共振成像(MRI)开始用于 CTS 患者,以直接观察正中神经并检查神经结构发生的变化:在这项研究中,使用核磁共振成像测量了 CTS 患者腕部不同水平的正中神经面积,研究了其与信号增加的关系,并将其与肌电图的结果进行了比较:研究共纳入了 35 名确诊为 CTS 的患者。研究对象包括肌电图测试结果为正常-轻度和中度-重度的患者;通过腕部核磁共振成像检查正中神经在不同水平的面积/平方毫米,以及信号是否增加。此外,还对成像中的腓肠肌进行了评估:在参与研究的 35 名患者中,有 24 名女性(68.6%)和 11 名男性(31.4%)。在桡尺骨远端交界处(DRUJ)测量的正中神经平均面积(以平方毫米为单位)和在锤骨水平测量的正中神经平均面积(以平方毫米为单位)显示,肌电图阳性患者的DRUJ和锤骨距离测量值更高。肌电图检查结果在信号增高的患者中也明显呈阳性:结论:在某些情况下,通过病史和体格检查或采用被认为是金标准的肌电图等确诊测试,可以很容易地诊断出 CTS。磁共振成像可作为 CTS 患者正中神经成像的替代方法。在我们的研究中,肌电图结果在磁共振成像信号增高的患者中也呈显著阳性,因此磁共振成像是一种可取的方法,尤其是在软组织相关病理病例中。

期刊介绍: Advances in Clinical and Experimental Medicine has been published by the Wroclaw Medical University since 1992. Establishing the medical journal was the idea of Prof. Bogumił Halawa, Chair of the Department of Cardiology, and was fully supported by the Rector of Wroclaw Medical University, Prof. Zbigniew Knapik. Prof. Halawa was also the first editor-in-chief, between 1992-1997. The journal, then entitled "Postępy Medycyny Klinicznej i Doświadczalnej", appeared quarterly. Prof. Leszek Paradowski was editor-in-chief from 1997-1999. In 1998 he initiated alterations in the profile and cover design of the journal which were accepted by the Editorial Board. The title was changed to Advances in Clinical and Experimental Medicine. Articles in English were welcomed. A number of outstanding representatives of medical science from Poland and abroad were invited to participate in the newly established International Editorial Staff. Prof. Antonina Harłozińska-Szmyrka was editor-in-chief in years 2000-2005, in years 2006-2007 once again prof. Leszek Paradowski and prof. Maria Podolak-Dawidziak was editor-in-chief in years 2008-2016. Since 2017 the editor-in chief is prof. Maciej Bagłaj. Since July 2005, original papers have been published only in English. Case reports are no longer accepted. The manuscripts are reviewed by two independent reviewers and a statistical reviewer, and English texts are proofread by a native speaker. The journal has been indexed in several databases: Scopus, Ulrich’sTM International Periodicals Directory, Index Copernicus and since 2007 in Thomson Reuters databases: Science Citation Index Expanded i Journal Citation Reports/Science Edition. In 2010 the journal obtained Impact Factor which is now 1.179 pts. Articles published in the journal are worth 15 points among Polish journals according to the Polish Committee for Scientific Research and 169.43 points according to the Index Copernicus. Since November 7, 2012, Advances in Clinical and Experimental Medicine has been indexed and included in National Library of Medicine’s MEDLINE database. English abstracts printed in the journal are included and searchable using PubMed http://www.ncbi.nlm.nih.gov/pubmed.
