[摘要] 目的 探討神經(jīng)根型頸椎病DWIBSS表現(xiàn)及其應(yīng)用。方法 總結(jié)分析31例中、重度神經(jīng)根型頸椎病DWIBSS和MRM表現(xiàn)。 結(jié)果 在DWIBSS圖像中,除C4外,C5~T1神經(jīng)干幾乎均可顯示,并追蹤到腋神經(jīng)。 MRM成像能顯示整個頸和上胸段脊髓、各神經(jīng)根袖和其內(nèi)走行的神經(jīng)根。頸、臂叢的各神經(jīng)結(jié)構(gòu)DWIBSS顯示情況間(x2=778.3, P<0.01)。結(jié)論 DWIBSS結(jié)合MRM對神經(jīng)根型頸椎病評價具有一定的臨床應(yīng)用價值。

[Abstract] Objective To explore the MRI findings of diffusion-weighted images with the background signal suppression and MRI myelography of cervical radiculoPathy spondylosis its useful value. Methods The presents of DWIBSS and MRM of the 31 cases wiith the moderate severe nerve root type cervical radiculoPathy spondylosis were reported. Results Except to C4, C5 ~ T1 neural stem almost could been displayed,and traced to the axillary nerve in the DWIBSS image. The statistically significant results of the entire nerve root sleeve and running within the nerve root of the cervical upper thoracic spinal cord could been displayed in MRM imaging. Between the findings of DWIBSS of the cervical brachial neural structures were shown Significant(x2=778.3, P<0.01). Conclusion DWIBSS combining MRM of the cervical radiculopath spondylosis has a clinical value

MRI包括頸、臂叢全身背景信號抑制彌散加權(quán)(diffusion weighted imaging with the background signal suppression,DWIBSS)和MR脊髓成像(MRI Myelography,MRM)等是主要神經(jīng)成像技術(shù)。迄今為止,文獻(xiàn)對DWIBSS等MRI表現(xiàn)在神經(jīng)根型頸椎病MRI表現(xiàn)的研究甚少。筆者做了一些初步研究,現(xiàn)報道如下。
1 資料與方法
1.1 一般資料
選自2010年8月~2012年9月,因中、重度神經(jīng)根型頸椎病(簡稱頸椎病組)在本院診療的31例臨床資料。31例均經(jīng)各種影像學(xué)檢查(頸胸椎X線片、CT或和MRI),所有患者均符合神經(jīng)根型頸椎病有關(guān)臨床診斷標(biāo)準(zhǔn)[2]。本組患者年齡35~65歲,平均年齡為(47.50±10.86)歲。臨床上表現(xiàn)為病側(cè)頸項部、肩胛部、前臂有程度不一疼痛,頸~臂和上肢感覺異常及肱二、三頭肌腱等反射減弱,較嚴(yán)重的患者科出現(xiàn)頸、臂叢所屬肌群萎縮等。
1.2 MRI掃描儀和檢查方法
采用Phillips Aura Pulsa HP 1.5T磁共振掃描儀。選擇頭頸聯(lián)合線圈,受檢者取仰臥位,平靜呼吸。頸椎MRI冠狀位掃描:(1)FSE T1WI TR 600 ms,TE20 ms,翻轉(zhuǎn)角150°,層厚5 mm,層間距1 mm,視野320,矩陣320;(2)矢狀位及橫斷位掃描,T2WI FSE TR 4 000 ms,TE 39 ms,翻轉(zhuǎn)角120°,層厚5 mm,層間距0 mm,視野320,矩陣320×320,結(jié)合STIR技術(shù)。(3)頸神經(jīng)根成像技術(shù)(3D Diffusion Weighted Imaging with the Background Signal Suppression,DWIBSS):TR 9 000 ms,TE280 ms,層厚1 mm,層間距0 mm,層數(shù)120,采用短TI時間脂肪抑制,TI200 ms,F(xiàn)OV320 mm或448 mm,矩陣448×320,Turbo 因子和EPI因子均為53,體素1 mm×1 mm×1 mm,采用SENCE-NV16并行采集技術(shù)。……
