【摘要】:目的通過(guò)MRI對(duì)青少年頸椎椎間盤的測(cè)量,為人工間盤設(shè)計(jì)、置換及椎間盤相關(guān)疾病診治提供理論依據(jù)。方法用SIGNA MR/1.5T磁共振對(duì)40例正常青少年(14~17歲)頸椎間盤矢狀位多層面的高度及前后徑測(cè)量:以頸椎正矢狀面為中心,分別向兩側(cè)以3 mm為間隔,掃描5組矢狀位圖像,選擇正中層面測(cè)量椎間盤中心高度與前后徑,由兩名MRI副主任醫(yī)師測(cè)量后取平均值。結(jié)果 (1)頸椎間盤前后徑為(14.036±1.812)mm,中心高(4.111±0.813)mm;(2)從C_(2~3)到C_(6~7)各組椎間盤前后徑和中心高組間比較均無(wú)統(tǒng)計(jì)學(xué)差異(均P0.05)。(3)按性別各組椎間盤前后徑和中心高組間比較均無(wú)統(tǒng)計(jì)學(xué)差異(均P0.05)。結(jié)論 (1)14~17歲青少年頸椎椎間盤高度、前后徑各值從C_(2~7)呈漸增趨勢(shì),各測(cè)量值間無(wú)統(tǒng)計(jì)學(xué)差異。(2)MRI可直觀顯示青少年頸椎間盤形態(tài),測(cè)量數(shù)據(jù)能夠滿足人工椎間盤選擇需要。
