Assessment of the Cervix in Pregnant Women Using Shear Wave Elastography: A Feasibility Study

Ultrasound Med Biol. 2015 Nov;41(11):2789-97. doi: 10.1016/j.ultrasmedbio.2015.06.020. Epub 2015 Aug 14.


The quantitative assessment of the cervix is crucial for the estimation of pre-term delivery risk and the prediction of the success of labor induction. We conducted a cross-sectional study using shear wave elastography based on the supersonic shear imaging technique. The shear wave speed (SWS) of the lower anterior part of the cervix was quantified over an 8-mm region of interest in 157 pregnant women. Cervical SWS is slightly but significantly reduced in patients diagnosed with pre-term labor and in patients who actually delivered pre-term.
