摘要
胎儿期心胸比增大常提示胎儿心功能不全;心胸比减小提示心脏受压,静脉系统回流受阻,反映胎儿情况较危急。产前明确诊断对病因查找、评估预后及宫内治疗有至关重要的作用。超声具有经济、无创、实时、便捷等特点,一直作为胎儿产前诊断首选的影像学方法,但其存在许多局限性。随着技术不断发展,MRI能为心胸比异常胎儿病因诊断及预后评估提供更多信息。
The increase of fetal cardiothoracic ratio often indicates fetal cardiac insufficiency, the decrease of cardiothoracic ratio indicates compression of the heart, obstruction of venous reflux, and the critical condition of the fetus. A clear prenatal diagnosis is essential for pathogenesis search, prognosis evaluation and intrauterine treatment. Ultrasound as a economic, noninvasive, real-time, convenient technology, has always been the preferred imaging method for prenatal diagnosis of fetuses, but it has many limitations. With the development of technology, MRI can provide more information for the etiological diagnosis and prognosis assessment of abnormal cardiothoracic ratio fetus.
