研究设计。目的利用磁共振成像和椎间盘成像技术，探讨间盘源性腰痛与间盘形态的相关性。目的：评估间盘源性腰痛患者在磁共振成像上所见的各种病理参数，并将其与椎间盘造影的观察结果相关联。虽然之前已经进行了大量的研究，但磁共振成像的各种病理结果与鼓室造影术引起的疼痛再现之间的相关性还没有完全解释。对39例患者的101个腰椎间盘进行了磁共振成像和疼痛刺激腰椎间盘造影检查。当腰椎间盘造影下疼痛再现一致时，用3个统计参数对磁共振成像上的各种病理参数进行分析，以确定相关的磁共振成像结果。放射状撕裂通常在磁共振成像上显示在椎间盘上，而在椎间盘造影上显示出一致的疼痛。这些撕裂的存在并不是椎间盘造影术中疼痛的可靠预测指标。虽然T2加权图像上的高信号区是一个相对可靠的疼痛预测指标，但其统计值低于之前的研究。在这一人群中，大量退变和严重的椎间盘高度丧失是罕见的。这些发现可以很好地预测注射腰椎间盘时的疼痛。尽管合并后方环状撕裂的腰椎间盘可能会产生疼痛，但这些征象对预测间盘源性腰痛的有效性是有限的。
Study Design. The correlation between discogenic lumbar pain and disc morphology was investigated by using magnetic resonance imaging and discography.Objectives. To assess the various pathologic parameters seen on magnetic resonance imaging in patients with discogenic lumbar pain and to correlate them with observations on discography.Summary of Background Data. Although numerous previous studies on the subject have been performed, the correlations between various pathologic findings on magnetic resonance imaging and pain reproduction by provoked discography have not been explained fully.Methods. One hundred and one lumbar discs in 39 patients were studied with magnetic resonance imaging and pain provocation discography. When pain reproduction under discography was concordant, various pathologic parameters on magnetic resonance imaging were analyzed by three statistical parameters to determine the associated magnetic resonance imaging findings.Results. Radial tears commonly are demonstrated on magnetic resonance imaging in discs with concordant pain on discography. The presence of these tears is not a reliable predictor of a painful disc on discography. Although a high-intensity zone on T2-weighted images is a relatively reliable predictor of pain, the statistical values were lower than those in previous studies. Massive degeneration and severe disc height loss were rare in this population. These findings were good predictors of pain on disc injection.Conclusions. Although the lumbar intervertebral discs with posterior combined anular tears are likely to produce pain, the validity of these signs for predicting discogenic lumbar pain is limited.
