Purpose: To evaluate the correlation between preterm delivery before 37 weeks of gestation and ultrasound elastography strain measurement of the cervical stiffness. Material and methods: In this prospective study 255 pregnant women were examined vaginally by ultrasound elastography (Aplio XG Ultrasound System Toshiba Medical Systems Europe, Netherlands). Four circular ROIs (Region Of Interests) were placed in a standardized pattern on the relaxed anterior cervical lip. In a validation phase raw datasets of 34 randomly chosen women were evaluated by TDI-Q software (Tissue Doppler Quantification Software, Toshiba…
