Abstract:
Objective:To investigate the diagnostic value of two-dimensional ultrasound combined with volumetric contrast imaging (VCI) and magnetic resonance imaging (MRI) for the developmental abnormalities of the fetal corpus callosum.Methods:Seventy-three fetuses who underwent cranial MRI within 1 week after suspected fetal corpus callosum dysplasia on ultrasound and received a definitive diagnosis in the neonatal period were retrospectively recruited for the study. The fetal corpus callosum was observed in the transverse, coronal, and sagittal views of the fetus, and the hyaline septal cavity, lateral ventricle, third ventricle, and corpus callosum were observed in the MRI scan. The diagnostic results and sensitivity of two-dimensional ultrasound combined with volumetric contrast imaging and MRI were analyzed.Results:Neonatal imaging showed that among 73 fetuses, 32 had agenesis of the corpus callosum, 29 had hypoplasia of the corpus callosum, and 12 had normal development of the corpus callosum. The differences in diagnostic results and sensitivity between 2D ultrasound combined with volumetric contrast imaging and MRI testing for agenesis of the corpus callosum were not statistically significant (all P>0.05), and the differences in diagnostic results and sensitivity for hypoplasia of the corpus callosum were statistically significant ( P<0.05). Conclusions:Both 2D ultrasound combined with volumetric contrast imaging and MRI are of high value for the diagnosis of partial-type agenesis of the corpus callosum, but MRI is more advantageous for the diagnosis of agenesis of the corpus callosum, and MRI can be a useful supplement and verification tool for ultrasound to provide a more accurate clinical diagnosis.
