New onset or exacerbation of preexisting neurologic symptoms during pregnancy often necessitates brain or spinal cord imaging. Magnetic resonance techniques are preferred imaging modalities during pregnancy and the postpartum period. Ionizing radiation with computed tomography and intravenous contrast material with magnetic resonance or computed tomography should be avoided during pregnancy. New onset of headaches in the last trimester or in the postpartum period may indicate cerebrovascular disease or a mass lesion, for which brain imaging is necessary. The continuum of cerebrovascular complications of pregnancy and enlarging lesions may produce neurologic symptoms later in pregnancy and after delivery, necessitating imaging.
怀孕期间新发或原有神经系统症状恶化通常需要进行脑部或脊髓成像检查。在怀孕期间和产后，磁共振技术是首选的影像学检查方式。应避免在怀孕期间使用计算机断层扫描的电离辐射和磁共振或计算机断层扫描的静脉造影剂。妊娠晚期或产后新发头痛可能提示脑血管病或肿块病变，需要进行脑部成像检查。妊娠期间和分娩后，脑血管并发症的连续进展和扩大的病变可能会导致神经系统症状，需要进行影像学检查。
