Abstract:The goal of this study was to associate the echogenicity of the cervix at 12 weeks pregnancy to the mode of delivery. Calibration of ultrasound images was necessary due to the use of data from different hospitals. There were differences between the images per device, despite the pre-set. The calibration is done based on phantom data and data of the vastus lateralis muscle, which functioned as control data. Three different corrections are applied in a semiautomatic calibration method. This method has an accuracy of approximately 4.5% a 5.5% and is suitable for the images obtained with the abdominal probe, with the Bergman device or the UMC Utrecht device. A reliable and reproducible method developed is to determine the echogenicity of the cervix. The anterior lip showed the best results compared to the posterior lip, based on correlations, standard deviations and standard error. Thereafter, 211 scans of the cervix from St. Antonius and UMC Utrecht have been analysed and associated to five different modes of delivery; vaginal, assisted delivery, primary caesarean section, secondary caesarean section because of fetal distress and secondary caesarean because of failure to progress. No significant differences in echogenicity between these groups are found.
