The aim of this study was to evaluate the usefulness for lumbar disc herniation of enhanced imaging with a nonionic contrast gadolinium complex (Gadoteridol). Among 130 discs in 26 patients, 27 herniated discs were shown on MR sagittal imaging. They were classified into 4 types according to the enhancement pattern of the disc on MR sagittal imaging (Type Ia: nonenhancement, Type Ib: globular enhancement, Type II: strong enhancement, Type III: ring enhancement). The results were as follows: Type Ia: 3, Type Ib: 15, Type II: 7, Type III: 2. A total of herniated discs were enhanced with Gadoteridol. Surgery was performed in 5 patients (Type Ib: 1, Type II: 4). The herniated disc of Type Ib extruded but did not rupture the posterior ligament, whereas the herniated discs of Type II extruded and ruptured the posterior ligament. Thus, the herniated discs were enhanced with the nonionic contrast agent Gadoteridol. If the disc herniates over the posterior ligament, it might be strongly enhanced. Therefore, enhanced MR imaging is thought to be useful to establish the diagnosis of lumbar disc herniation.
本研究的目的是评估非离子型钆造影剂（钆特醇）增强成像对腰椎间盘突出症的应用价值。在26例患者的130个椎间盘中，磁共振矢状位成像显示27个椎间盘突出。根据磁共振矢状位成像上椎间盘的强化模式将其分为4型（Ia型：无强化，Ib型：球状强化，II型：强烈强化，III型：环状强化）。结果如下：Ia型3个，Ib型15个，II型7个，III型2个。共有突出的椎间盘用钆特醇增强。5例患者接受了手术（Ib型1例，II型4例）。Ib型突出的椎间盘挤出但未破裂后纵韧带，而II型突出的椎间盘挤出并破裂后纵韧带。因此，突出的椎间盘用非离子型造影剂钆特醇增强。如果椎间盘突出超过后纵韧带，可能会强烈强化。因此，增强磁共振成像被认为对腰椎间盘突出症的诊断有帮助。
