Lactic acid gel (LVG) is safe and as efficacious as metronidazole in the treatment of BV. There is evidence that LVG when combined with metronidazole is superior to metronidazole alone in promoting lactobacilli colonization. LVG as an adjunct to metronidazole, having the least number of recurrent BV, appears to result in better long-term treatment effect on bacterial vaginosis.

Methods: Thirty fetuses were included in the study. Cephalic volumes were twice acquired prospectively. Measurements of the biparietal diameter (BPD) and head circumference (HC) were performed from volumes by two experienced sonographers and by SmartPlane ® software. These measurements were both compared to those obtained with automated calipers positioning and to conventional 2D measurements. Means and SD of the differences between the series of measurements were calculated. Intra and interobserver reproducibilities were assessed using intraclass correlation coefficient (ICC). Bland & Altmann plots were used to evaluate the agreement between the series of measurements. Results: Intra and interobserver reproducibilities were high regardless of the measurement technique (ICC> 0.99 for both). The maximum average difference between two series of measurements was 1.12 mm +/-0.86 and 4.02 mm +/-2.8 for the biparietal diameter and the head circumference, respectively. For these two parameters, the agreement between software and operators was very high (95% of the observed differences were <2.5 mm and <4 mm for the BPD and the HC respectively). Conclusions: Agreement between measurements performed from 3D volumes by software and conventional 2D measurements is high and comparable to agreement observed between semi-automatic and conventional 2D measurements. Reproducibility of these measurements is similar to those observed in experienced sonographers. EP22.21Magnetic resonance in fetal cerebral lesions
