Ultrasonography (US) remains the first method in the evaluation of fetal central nervous system (CNS) abnormalities but in case of the spinal canal and cord it is often insufficient since the bony structures may obscure these structures. Prenatal magnetic resonance imaging (MRI) is therefore the final noninvasive tool for the assessment of these malformations allowing for correction of sonographic findings, revealing the full extent of complex lesions and choosing the candidates for in utero treatment. The authors present the most frequent anomalies of spinal canal and spinal cord in the consecutive phases of pregnancy, illustrated with their own MR images, with reference to the literature and own experience. In 58 out of 252 fetuses examined due to suspicion of CNS anomalies (23.0%) the spinal canal and spinal cord abnormalities were found on MRI. The cases of diastematomyelia, myelomeningocele, tethered cord, caudal regression syndrome, anterior meningocele, cystic sacrococcygeal teratoma and syringohydromyelia are demonstrated.
超声检查（US）仍然是评估胎儿中枢神经系统（CNS）异常的首选方法，但对于椎管和脊髓来说，它往往并不充分，因为骨骼结构可能会遮挡这些结构。因此，产前磁共振成像（MRI）是评估这些畸形的最终无创工具，它可以校正超声检查结果，揭示复杂病变的全貌，并选择宫内治疗的候选对象。作者结合文献和自身经验，展示了妊娠各阶段最常见的椎管和脊髓异常，并配以自己的磁共振图像。在因怀疑中枢神经系统异常而接受检查的252例胎儿中，有58例（23.0%）通过MRI发现了椎管和脊髓异常。文中展示了脊髓纵裂、脊髓脊膜膨出、脊髓拴系、尾椎退化综合征、前脑膨出、骶尾部囊性畸胎瘤和脊髓空洞症的病例。
