Fetal 32 weeks midline brain echogenicity MRI is fine, whether there is anything wrong with the chromosomes can not be determined, because the results of the MRI can not be used to determine whether the chromosomes are abnormal. MRI can only check whether there is any abnormality in the fetal structure, it cannot check whether there is any abnormality in the fetal chromosomes. For a 32-week-old fetus showing no echoes in the midline of the brain, a normal MRI can only indicate that the structures within the fetal cranium are normal, but it cannot determine the chromosomes. To determine whether the chromosomes are abnormal, it is recommended that amniocentesis be performed, and DNA is extracted from the cells for molecular genetics to understand the chromosomal situation. Fetus at 32 weeks of midline echogenicity, and MRI is fine, want to determine whether the chromosomes are not fine, it is recommended to consult a doctor in a timely manner, after the doctor’s visit combined with the relevant items of the examination, a comprehensive judgment.
