Objective To assess the intra-and interobserver reproducibility of ultrasound measurements of fetal biometric parameters. BPD, AC, HC and FL were as follows: 0.996 (0.995, 0.997), α 0.998; 0.994 (0.992, 0.996), α 0.997; 0.996 (0.994, 0.997), α 0.998; and 0.994 (0.992, 0.996), α 0.997, respectively. Similarly, the inter-CC with the 95% CI and RC for the same parameters were as follows: 0.995 (0.993, 0.997), α 0.998; 0.980 (0.971, 0.990), α 0.990; 0.994 (0.992, 0.996), α 0.997; and 0.990 (0.985,0.993) Methods Results Reliable consensus was observed for both the intra-CC and inter-CC and RC for all four biometric parameters. The intra-CC with the 95% CI and RC for the

There is a learning curve for ultrasonographic estimates of fetal weight, with a significant decrease in the percent error seen with advancing training among residents, reaching acceptable levels of more than 70% of estimates within 10% of birth weight after 24 months of ultrasonographic experience.

A sonographic evaluation of umbilical cord coiling in the second trimester correlates with the true UCI at birth, although the sensitivity in predicting coiling patterns as hypocoiled and hypercoiled cords is less accurate. A difference between the aUCI and matched UCI at birth could be explained by a sonographic error in the sampling of different umbilical cord segments with discordant coiling patterns or the possibility of a dynamically evolving UCI with advancing gestational age.

Fetuses with an isolated single umbilical artery are at similar risk for SGA compared with fetuses with 3-vessel umbilical cords. It appears that antepartum serial ultrasound examination does not provide more information for interval fetal growth assessment in fetuses with an isolated single umbilical artery.

The goal of this prospective study was to develop a new scoring system using transvaginal color and pulsed Doppler characterization of ovarian lesions. Transvaginal color Doppler sonography was performed on 812 women, among whom 174 adnexal masses were found and analyzed. Ovarian lesions were assessed by means of morphological and color Doppler scoring systems. Tumors were characterized ultrasonically as benign or suspected of being malignant. Scoring system results were correlated with histopathological findings. Among our study group, 38 malignant and 136 benign ovarian tumors were found and verified. The color Doppler scoring system was very useful in distinguishing benign from malignant masses, with a sensitivity of 97.3% and a specificity of 100%, compared with the morphological scoring system's sensitivity of 92.1% and specificity of 94.8%. We also evaluated a combination of both scoring systems. We believe that new color Doppler scoring system maximizes the ability to discriminate between benign and malignant entities.
