Failure to respond to conservative treatment and recurrent disease after operative intervention are the major indications for diagnostic imaging in degenerative disc disease. In recent years computed tomography (CT) has widely replaced myelography, and now CT is giving way to magnetic resonance imaging (MRI). MRI yields diagnostic information comparable to that obtained with myelo-CT, yet spares the patient the need for intrathecal contrast administration or exposure to ionizing radiation. In the postoperative spine, contrast-enhanced MRI has proven more accurate than CT in distinguishing epidural scar formation from recurrent disk herniation.
保守治疗无效以及手术干预后疾病复发是退行性椎间盘疾病进行诊断性成像的主要指征。近年来，计算机断层扫描（CT）已广泛取代脊髓造影，而如今CT又逐渐被磁共振成像（MRI）所取代。MRI产生的诊断信息与脊髓CT相当，但无需患者进行鞘内造影剂注射或接受电离辐射。在脊柱术后，增强磁共振成像在区分硬膜外瘢痕形成与复发性椎间盘突出方面已被证明比CT更准确。
