EP02.31: BiometryAssist® Versus Manual Approach for Fetal Biometry: Correlation, Level of Agreement and Comparison of Acquisition Time
ULTRASOUND IN OBSTETRICS & GYNECOLOGY(2023)
摘要
In this pilot cohort study, we included 34 consecutive pregnant women attending our Obstetrics Unit during their 2nd/3rd trimester. We acquired standardised US views for the measurement of biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL), and we estimated fetal weight (EFW). Biometry was blindly measured manually and using the BiometryAssist tool (Samsung Hera w10 US machine) and the measuring time for each approach was recorded. Pearson correlation coefficient, intraclass correlation coefficient (ICC), and student's t-test (mean comparison) were used. Pearson correlation coefficient between BA and manual measurements was close to 1 for all measurements, indicating high correlation and excellent agreement between BA and manual measurements. Mean differences between BA and manual measurements were not significantly different (table 1). The BA method was faster than the manual approach (mean 56.2 vs. 69.2 seconds, respectively [95%CI of the difference 4.4, 21.6, p-value: 0.004]). BA assessment of fetal biometry shows high correlation, excellent agreement, and similar mean values compared to manual ones at a sorter acquisition time.
