The purpose of the study was to compare the diagnostic values of prenatal ultrasound and MR in the foetal central nervous system defects.  

385 MR were performed in the pregnant women with the ultrasound suspiction of foetal defect. US was conducted with the Voluson-Kretz730PRO. In 158 cases (41%) foetal CNS defect was found. MR was performed with the 1.5T system, torso surface coil, SSFSET2 sequence. MR results were compared with prenatal US and verified after the delivery by physical tests, US, TK and surgery or, in cases of the infant death, with a pathomorphological examination.  

Out of 158 infants, 8 died after the delivery, 93 were consulted in the neurosurgical clinic, 19 underwent a neurosurgery treatment, and the remaining 7 infants' fate is unknown. Foetal MR widened the pertinent US diagnoses in 62%. The 100% compliance has pertained to the hydrocephalus and the anencephaly. US results failed in some cases of: corpus callosum agenesis, aqueductal stenosis, intracranial cyst, holoprosencephaly, schizencephaly, Dandy-Walker complex, syringomyelia, diplomyelia, myelomeningocele. In 15 cases, MR completely changed the prognosis and treatment (holoprosencephaly, myelomeningocoele, diplomyelia, intracranial cyst, lung hypoplasia, urinary bladder agenesis - not detected during prenatal US). Postnatal examinations and surgery confirmed the results of prenatal MR.

MR compared with prenatal US, proved better effectiveness in imaging of foetal CNS defects, especially in the imaging of the posterior fossa structures, the ventricular system, the corpus callosum, the evaluation of meningocoele contents and the complex malformations of the central nervous system.
