Shear‐wave sonoelastographic assessment of cervix in pregnancy

Introduction The aim of this study was to investigate the differences in shear‐wave sonoelastography (SWS) scores between the different parts of cervix, explore the association between the cervical SWS scores with cervical length and evaluate repeatability of the measurement of cervical SWS scores. Material and methods This was a prospective study performed in women with singleton pregnancy at 11‐13+6 (n = 676), 16‐20+6 (n = 364), 21‐24+6 (n = 338) and 28‐32+6 weeks (n = 304). The SWS scores were obtained at the inner, middle and external parts of the cervix, using a transvaginal ultrasound approach. Results The SWS scores of the inner cervix were significantly higher than the measurements acquired at the middle and external parts (all P
