Value of Prenatal 3D HD-Live Flow in the Evaluation of True and False Knots of the Umbilical Cord.
Abstract: In this study, 3D HD-live Flow was used to differentiate true and false knots. The study involved 9161 fetuses who underwent ultrasound during the 13th to 40th week of pregnancy. Among them, 38 cases of true knots of umbilical cord were found, with 24 cases correctly identified by 3D HD-live Flow, representing a detection rate of 63.2%. There were 19 cases of false knots of umbilical cord, with 13 cases correctly identified by 3D HD-live Flow, representing a detection rate of 68.4%.The detection rates of true knots of umbilical cord by 2D ultrasound and color Doppler ultrasound were significantly lower than that of 3D HD-live Flow (P < 0.05). However, there was no significant difference in detection rate between color Doppler ultrasound and 2D ultrasound (P > 0.05).This study demonstrates that 3D HD-live Flow is an effective imaging technique for distinguishing true and false knots of the umbilical cord in the prenatal period. It has the potential to improve the accuracy of diagnosis and provide valuable information for clinical management.
