To describe advances in magnetic resonance technology and the current indications and advantages of magnetic resonance imaging that have led to increased utilization in fetal medicine.
The article covers the most common uses of magnetic resonance imaging in fetal medicine. The advantages of magnetic resonance imaging for the diagnosis of fetal malformations are described, in particular the advantages of magnetic resonance imaging in central nervous system malformations not optimally diagnosed by ultrasound are described. These cases include malformations of migration, malformations of development, such as agenesis of the corpus callosum, and destructive lesions. Noncentral nervous system lesions include chest abnormalities, abdominal wall defects, gastrointestinal and genitourinary abnormalities and fetal neoplasms. Abnormalities of placentation and other maternal factors affecting pregnancy are shown.
Recent studies have shown that magnetic resonance imaging can add significantly to the prenatal diagnosis and management of congenital abnormalities. In addition, placental abnormalities have been diagnosed with greater accuracy.
描述磁共振技术的进展以及磁共振成像目前的适应证和优势,这些已导致其在胎儿医学中的应用增加。
本文涵盖了磁共振成像在胎儿医学中最常见的用途。描述了磁共振成像在诊断胎儿畸形方面的优势,尤其阐述了磁共振成像在超声未能最佳诊断的中枢神经系统畸形中的优势。这些病例包括迁移畸形、发育畸形,如胼胝体发育不全,以及破坏性病变。非中枢神经系统病变包括胸部异常、腹壁缺损、胃肠道和泌尿生殖系统异常以及胎儿肿瘤。展示了胎盘植入异常和其他影响妊娠的母体因素。
近期研究表明,磁共振成像可显著辅助先天性异常的产前诊断和管理。此外,胎盘异常的诊断准确性更高。
