Value of Prenatal MRI Screening on Fetal Cavum Septum Pellucidum Dysplasia
Objective To explore the application value of prenatal MRI screening on fetal cavum septum pellucidum(CSP)dysplasia.Methods The clinical data of 465 pregnant women who received prenatal examination in the hospital were retrospectively analyzed from January 2021 to January 2024.All samples were examined by prenatal ultrasound.The ultrasound results showed 60 cases of fetal CSP abnormality,and further MRI was performed.The types of fetal CSP dysplasia were recorded,and the diagnostic efficiency of the two detection methods was compared.Results Ultrasound detection showed small CSP in 16 cases(26.67％),widened CSP in 12 cases(20.00％),not displayed CSP in 10 cases(16.67％),not displayed CSP with corpus callosum agenesis in 9 cases(15.00％),CSP loss in 6 cases(10.00％),CSP echo abnormality in 5 cases(8.33％),and alobar forebrain in 2 cases(3.33％).MRI examination showed that the CSP was small in 18 cases(30.00％),the CSP was widened in 14 cases(23.33％),CSP was not shown in 11 cases(18.33％),CSP was not shown and the corpus callosum was not developed in 10 cases(16.67％),and the CSP was missing in 7 cases(11.67％).The sensitivity of MRI was significantly higher than that of ultrasound,and the missed diagnosis rate was significantly lower than that of ultrasound(P＜0.05).Conclusion MRI can enhance the accuracy rate of prenatal fetal cavum septum pellucidum dysplasia.
