Short oral presentation abstractsObjectives: In recent years efforts have been made to study three-dimensional biometry as a method for fetal brain assessment. In this study, we aimed to compare brain volumes of fetuses with CMV infection and non-infected controls. Also, we wanted to assess if there is a correlation to their neurodevelopmental outcome as observed after several years. Methods: A retrospective cohort study examined MRI brain scans of 42 fetuses (at 30-34 weeks gestational age) that were diagnosed with intrauterine CMV infection. Volumetric measurements of 6 structures were assessed using a semi-automated designated program, and compared to a control group of 50 fetuses. Data collected included: prenatal history, MRI and sonographic, neuro-developmental follow-up. Results: We found that all brain volumes measured were smaller in the CMV-infected group and that there is a correlation between smaller cerebellar volume and lower VABS-II questionnaire scores, especially in the fields of daily living and communication skills. Conclusions: In this study we found that brain volumes are affected by intrauterine CMV infection and that it has a developmental prognostic meaning. Such information, which should be supported by further research, may help clinicians to further analyse imaging data, and treat and make a better assessment of these fetuses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
