Abstract:
Objective To explore the value of MRI in detecting the corpus callosum agenesis suspected by US.Methods 19 women with complicated pregnancies,aged from 20 to 37 years(average 28 years) and with gestation from 20 to 38weeks(average 29 weeks) were studied with a 1.5 T superconductive MR unit within 24 hours after ultrasound examinations and suspected with fetal corpus callosum agenesis.T2WI and T1WI were performed using HASTE and FLASH,respectively.The features of MRI and ultrasound were compared with that of autopsy or follow-up outcome.Results Of the 19 fetus,14 cases with fetal corpus callosum,3 cases with mild enlargement of lateral cerebral ventricle and 2 cases with leukodystrophy were confirmed by MRI.Of them,accompained with Dandy-Walker syndrome in one and lipoma of corpus callosum in one.One case of Dandy-Walker syndrome and microcephalus respectively missed by US was detected by MRI.Conclusion MRI is superior in displaying fetal corpus callosum agenesis than ultrasound,which is helpful in conforming the diagnosis of fetal corpus callosum,classification and additional cerebral anomalies.
