1.Ultrasonic measurement of fetal liver length and its clinical significance
Chinese Journal of Obstetrics and Gynecology 2001;36(3):140-142
Objective To establish the normal growth velocity of fetal liver length and compare them with those of intrauterine growth retardation, pregnant diabetes and maternal-fetal blood types imcopatible. Method Three hundred and five normal pregnant women and 24, 10, 16 pathological pregnant women of intrauterine growth retardation (IUGR), gestational diabetes and maternal-fetal blood types incompatible respectively had ultrasonographic measurement of fetal liver length at 18 to 42 weeks′ gestation. Results Normal fetal liver length has a linear relation to gestational age, and showed a significantly rapid increase after 28th week with a growth rate of 1.76 mm per week, and 1.00 mm per week before 28th week (P<0.05). The growth rate of IUGR group before and after therapy were 1.19 mm and 1.23 mm per week, significantly lower than those of normal group (P<0.05). The growth rate of pregnant diabetes group before and after therapy were 1.63 mm and 1.63 mm per week, no statistical significance with normal group (P>0.05). The growth rate of maternal-fetal blood types incompatible group before therapy was 1.98 mm, showed no difference with normal group (P>0.05), but after therapy, the growth rate of fetal liver was 1.38 mm per week, significantly lower than normal group (P<0.05). Conclusion Dynamic measurement of fetal liver length can help us to understand whether the fetus grow well in uterus and whether the treatments are effective.

Objective To evaluate the value of endometrial volume measurement and 3-dimensional power Doppler imaging(3D-PDI) in the differentiation between endometrial polyps and endometrial hyperplasia.Methods One hundred and fifty-six women who diagnosed as thick and inhomogeneous endometrium or hyperechogenic focal intrauterine structures by 2D ultrasound were enrolled,including 50 patients with endometrial polyps in the proliferative phase,51 cases with hyperplasia and 55 cases with normal histology or others.All were scheduled for hysteroscopy,dilatation and curettage,and the ultrasound was performed within 24 hours before the procedure. Endometrial volume, vascularity index (VI), flow index (FI) and vascularity flow index (VFI) were measured. These parameters were compared between endometrial polyps group and endometrial hyperplasia group.Results These parameters (endometrial volume,VI,FI and VFI) were all considered statistically significant between two groups.Conclusions Endometrial volume and 3D-PDI are good diagnostic tools in the differentiation between endometrial polyps and endometrial hyperplasia.
