Enhancement of lumbar nerve roots in the setting of degenerative disk disease has been considered by several authors as evidence of a breakdown in the blood-nerve barrier induced by nerve root compression [1-3]. Unfortunately, correlation between radicular enhancement and the clinically determined level of radiculopathy has not been consistently shown [4, 5]. We recently proposed that this phenomenon represents intravascular enhancement of radicular veins that travel adjacent to or within the endoneurium of one or more nerve roots of the cauda equina [4, 5]. Our purpose in this pictorial essay is to illustrate the appearance of radicular vein enhancement so that this phenomenon will not be misinterpreted as being clinically significant in the setting of degenerative disk disease.
几位作者认为，在椎间盘退变情况下腰椎神经根强化是神经根受压导致血神经屏障破坏的证据[1-3]。遗憾的是，神经根强化与临床确定的神经根病水平之间的相关性尚未得到一致证实[4,5]。我们最近提出，这种现象代表了与马尾一个或多个神经根的神经内膜相邻或在其内部走行的神经根静脉的血管内强化[4,5]。在这篇图文并茂的文章中，我们的目的是说明神经根静脉强化的表现，以免在椎间盘退变情况下将这种现象误解为具有临床意义。
