超声仍然是目前优生优育首选的影像学检查方法。但随着快速磁共振技术的应用,磁共振成像在胎儿的产前检查中体现出重要的价值,已成为产前超声诊断的重要补充。当产前超声检查不能确诊、不能明确病变程度及范围或难以判断胎儿预后时,尤其是对怀疑有中枢神经系统发育畸形的病例,有必要进行磁共振检查。文章主要阐述磁共振成像在监测胎儿发育状况、诊断胎儿发育畸形及其他病变中的应用。
Ultrasound is still the preferred imaging method for prenatal and postnatal care. However, with the rapid magnetic resonance technique, magnetic resonance imaging has shown great value in prenatal examination of the fetus and has become an important supplement to prenatal ultrasound diagnosis. When the prenatal ultrasound can not be diagnosed, can not determine the extent and extent of lesions or difficult to determine the prognosis of the fetus, especially for suspected cases of central nervous system deformity, the need for magnetic resonance imaging. The article mainly expounds the application of magnetic resonance imaging in monitoring fetal development, diagnosis of fetal malformations and other diseases.
