Characteristics and Diagnostic Efficacy of Prenatal Color Doppler Ultrasonography in Fetal Corpus Callosum Dysplasia
Objective:The aim of this study is to investigate the image characteristics and diagnostic efficacy of prenatal color Doppler ultrasound in fetal corpus callosum dysplasia.Methods:The results of prenatal color Doppler ultrasound of 150 pregnant women who were admitted to the Third Hospital of Mianyang from September 2022 to August 2023 were retrospectively analyzed to evaluate the development of fetal corpus callosum.The'gold standard'(postnatal neonatal MRI)was used to compare the results of ultrasound diagnosis,and Kappa test was used to analyze their consistency,and to explore the characteristics of ultrasound images and diagnostic efficacy.Results:Prenatal color Doppler ultrasound showed that among the 45 fetuses with corpus callosum dysplasia confirmed by the'gold standard',ultrasound accurately identified 43 cases,with a sensitivity of 96.47%,specificity of 99.92%,and accuracy of 99.93%.Ultrasound features included abnormal morphology of the corpus callosum,local hypoechogenicity,lateral ventricular dilatation and polyhydramnios.Multivariate regression analysis identified a number of risk factors and established a prediction model,and the prediction accuracy was 91.5%.Conclusion:Prenatal color Doppler ultrasound has high efficiency in the diagnosis of fetal corpus callosum dysplasia.Combined with image feature analysis and risk factor assessment,it is helpful for early clinical intervention and improvement of perinatal prognosis.
