A total of 18 fetuses with intracranial fluid accumulation who met the inclusion criteria were selected for MRI examination and image analysis. All fetuses completed the MRI examination within 32 weeks after ultrasound diagnosis and were followed up after the examination. The results showed that MRI could clearly show the intracranial fluid accumulation in fetuses and further clarify the growth and development of fetuses. Among the 18 fetuses, 14 were diagnosed as isolated fluid accumulation and 4 were structurally abnormal causing intracranial fluid accumulation. The degree of intracranial fluid accumulation could also be clearly displayed by MRI. Long-term follow-up results showed that all fetuses developed normally and no neurological developmental abnormalities or adverse effects were detected.In conclusion, the evaluation and follow-up of fetuses with intracranial fluid accumulation after ultrasound diagnosis by MRI are of great significance, which can provide more accurate 精品文档---下载后可任意编辑diagnostic results and guidance for patient follow-up and provide more reliable reference for clinicians. More clinical studies need to be conducted to further explore the application value of MRI in the diagnosis and follow-up of intracranial fluid accumulation in fetuses.Keywords: MRI; ultrasound; intracranial fluid accumulation in fetuses; evaluation; follow-up
