Elastography of the cervix for prediction of induction of labour

Background –Labour can be induced for various indications. This is done when it appears that benefits of induction outweigh its risk. Bishop score is the gold standard that is used to determine whether labour can be induced. However, the assessment of the cervix with digital examination is subjective and less reproducible. Elastography is an upcoming modality which is an ultrasound-based imaging technique used for assessing elasticity of tissues. It is based on the premise that softer tissues get more compressed than harder tissues when pressure is applied with ultrasound probe. Thereafter colour mapping is done depending on the gradient values of strain. Aim to assess whether elastography findings of uterine cervix can be used to predict successful induction of labour.
