MATERIALES Y METODOS:  Serie de casos, retrolectiva, basada en los registros de la Clínica de Defectos Estructurales. Criterios de inclusión: fetos con defectos en el sistema nervioso central. Las revisiones estructurales se recolectaron del expediente clínico y de los hallazgos reportados de la resonancia magnética. Se establecieron las comparaciones entre los hallazgos de los dos métodos, tomando en cuenta los diagnósticos finales establecidos después del nacimiento.  RESULTADOS: Se analizaron 58 casos; en 34 los hallazgos en la resonancia magnética y en el ultrasonido fueron exactamente los mismos. En 12 casos la resonancia magnética aportó información adicional y en otros 12 casos cambió el diagnóstico. Los defectos del tubo neural y las malformaciones de la línea media fueron los de mayor incidencia (n = 13 de cada uno). El ultrasonido tuvo la mayor tasa de falla para las anomalías de la formación cortical y las lesiones destructivas (29 y 33, respectivamente).  CONCLUSIONES: La resonancia magnética prenatal es una herramienta complementaria al ultrasonido que resulta útil en la evaluación de las anomalías del sistema nervioso central, principalmente en las alteraciones corticales. El ultrasonido y la resonancia tienen fortalezas y limitaciones; cada uno se desempeña mejor en distintos aspectos de la evaluación estructural del sistema nervioso central. Hasta el momento no existe evidencia suficiente para precisar la superioridad de uno en comparación con el otro.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract :  OBJECTIVE: To describe and compare all cases with central nervous system defects evaluated prenatally with structural ultrasound and magnetic resonance imaging.  MATERIALS AND METHODS: Case series, retrolective, based on the records of the Structural Defects Clinic. Inclusion criteria: fetuses with central nervous system defects. Structural revisions were collected from the clinical record and reported MRI findings. Comparisons between the findings of the two methods were established, considering the final diagnoses established after birth.  RESULTS: Fifty-eight cases were analyzed; in 34 cases the MRI and ultrasound findings were the same. In 12 cases the MRI provided additional information and in another 12 cases the diagnosis changed. Neural tube defects and midline malformations had the highest incidence (n = 13 of each). Ultrasound had the highest failure rate for cortical formation anomalies and destructive lesions (29 and 33, respectively).  CONCLUSIONS:  Prenatal MRI is a complementary tool to ultrasound that is useful in the evaluation of central nervous system abnormalities, primarily cortical alterations. Ultrasound and MRI have strengths and limitations; each performs better in different aspects of the structural evaluation of the central nervous system. So far there is insufficient evidence to pinpoint the superiority of one over the other.]]></p></abstract>
