摘要 随着腰椎间盘突出症发病率的升高,下腰痛已成为当今最为普遍、代价最高的健康问题之一。许多影像学技术被用于腰椎间盘突出症的诊断,其中,最为广泛使用的是X线、CT及MRI。但上述影像技术仍不能将腰椎间盘突出症患者的实际临床表现与影像学表现完全吻合,特异性比较低。因此,新的影像技术正被迫切需要。目前,弥散张量成像(DTI)作为一种新的影像学技术被用于腰椎间盘突出症的影像研究中。现已发现DTI可以定量测量腰椎间盘突出症患者中受卡压的神经根的各向异性分数值,从而判断神经根内水分子向各个方向的弥散能力。DTI的神经根示踪成像也可用于显示被腰椎间盘卡压的神经根,从而直观显示神经根的形态及走行情况。尽管目前DTI在腰椎间盘突出症中的研究还存在很多局限性,但DTI依然被认为是诊断腰椎间盘突出症所致神经根卡压的一种潜在的、具备临床实用性的影像技术。因此,更多DTI关于腰椎间盘突出症神经根受卡压的研究正迫切需要实施,以确认这项新技术在该疾病方面的应用。
