The spine is a complex mechanical structure that surrounds and protects the spinal cord and nerve roots. It is capable of multidirectional movement and is susceptible to a large variety of pathologies that can affect spinal cord and nerve root function. Detection of spinal pathology is aided by a familiarity with normal spinal anatomy and its appearance on CT and MRI studies. Imaging of the spine is performed frequently, and a systematic approach toward image interpretation can prevent overlooking or incompletely assessing a lesion.
CT and MRI of the spine provide detailed views of normal and abnormal structures and allow for differentiation of vascular, inflammatory, infectious, neoplastic, traumatic, and degenerative etiologies of spine disease.
This article provides a strategy for interpreting CT and MRI studies of the spine and can be used as a primer for the other articles that follow in this issue of CONTINUUM, in which specific etiologies of spine and spinal cord pathology are considered in detail.
脊柱是一个复杂的机械结构，它围绕并保护脊髓和神经根。它能够进行多方向运动，并且易受多种可影响脊髓和神经根功能的病理状况影响。熟悉正常脊柱解剖结构及其在CT和MRI检查中的表现有助于检测脊柱病变。脊柱成像检查频繁进行，采用系统的图像解读方法可防止漏诊或对病变评估不完整。
脊柱的CT和MRI能提供正常和异常结构的详细视图，并有助于区分脊柱疾病的血管性、炎症性、感染性、肿瘤性、创伤性和退行性病因。
本文提供了一种解读脊柱CT和MRI检查结果的策略，可作为本期《Continuum》后续其他文章的入门指南，后续文章将详细探讨脊柱和脊髓病变的具体病因。
