Abstract:
Objective To explore the growing change of sizes of lateral cerebral ventricle in second-third trimester normal fetuses in MRI,to provide the normal reference for clinical monitoring.Methods MRI findings in 98 normal second-third trimester fetuses were retrospectively analyzed.The fetuses were divided into 6 groups according to gestational age (unit:week)including 18-21,22-25,26-29,30-33,34-37 and 38-40 weeks,respectively.The maximum transverse sizes of fetal atrium and occipital horns of lateral ventricle (cm)were measured.The SigmaStat statistical program was used for statistical analysis.Results The length of lateral ventricle atrium horn in 6 groups were 0.35 ± 0.03,0.33 ± 0.05,0.31 ± 0.04,0.30 ± 0.03,0.26 ± 0.05 and 0.25 ± 0.04,respectively,and the ventricle length of occipital horns were 0.91± 0.09,0.84 ± 0.09,0.84 ± 0.1 1,0.81 ± 0.13,0.80 ± 0.1 1 and 0.74 ± 0.13,respectively.The length of lateral ventricle atrium horn and ventricle occipital horns among some differ-ent groups showed significant differences (P <0.05).The length of fetal ventricle atrium and occipital horn were reduced gradually with gestational ages.Conclusion The ventricular length of atrium and occipital horn in second-third trimester normal fetuses reduce gradually with gestational ages.
