The Diagnostic Value Of Mri On Fetal Spine And Spinal Cord Dysplasia

Objective To study the diagnostic value of MRI on fetal spine and spinal cord dysplasia.Methods A total of 78 pregnant women met the criteria and were included in this analysis from November 2017 to December 2021,whose age was from 18 to 39 years.The gestational age at fetal MR imaging was from 22 to 32 weeks.The results of prenatal magnetic resonance diagnosis were compared with those of prenatal ultrasound and follow-up to analyze the characteristics of fetal magnetic resonance on fetal spine and spinal cord dysplasia.Results Among the 78 fetuses,11 cases were normal,29 cases were vertebral dysplasia,16 cases were spinal cord dysplasia,22 cases were vertebral complex malformation.The coincidence rate of prenatal MRI diagnosis was 68.97%（20/29）,93.75%（15/16）and 100%（22/22）.The diagnostic coincidence rate of prenatal ultrasound was 86.21%（25/29）,50%（8/16）and 45.45%（10/22）,respectively.There was no statistical difference between the diagnostic coincidence rate of prenatal MRI and ultrasound for abnormal spinal cord development（P > 0.05）,and the diagnostic coincidence rate of prenatal MRI for abnormal spinal cord development and spinal cord compound malformation higher than prenatal ultrasound（P < 0.05）.Conclusion Fetal MRI is a useful diagnostic tool for spine and spinal cord dysplasia,especially spinal cord development.Based on prenatal ultrasound diagnosis,MRI can confirm and provide more diagnostic information.So as to provide a more definite prenatal diagnosis for clinical practice and make the better prenatal decision.
