The "wink" sign of nerve root cut-off seen on metrizamide-enhanced computerized tomography correlates well with compression of a lumbar nerve by a herniated disk. Seven of 46 patients had normal or equivocal myelograms, but had definite nerve root cut-off on metrizamide-enhanced CT scan. All seven patients were found to have a herniated lumbar disk at operation or a diskogram positive for herniation at the time of chymopapain injection. The wink sign is an additional objective finding that can be used in assessing the patient with sciatica.
在甲泛葡胺增强计算机断层扫描上看到的神经根切断的“眨眼”征与椎间盘突出对腰神经的压迫密切相关。46例患者中有7例脊髓造影正常或不明确，但在甲泛葡胺增强CT扫描中有明确的神经根切断。所有7例患者在手术时均发现有腰椎间盘突出，或在注射木瓜凝乳蛋白酶时椎间盘造影显示有突出。“眨眼”征是一项可用于评估坐骨神经痛患者的额外客观发现。
