Figure 1 Measurement of ultrasound shear wave speed. Left circle, the region of interest (ROI) of the upper point, right circle, ROI of the lower point. The diameter of the target regions of interest was set to 5 mm.
Figure 2 Schematic diagram of a twin view for measurement sites. A(left): elastographic map, B(right): grey-scale B mode that the measurement was done at the anterior lip of cervix 7.5 mm (lower point) and 17.5 mm (upper point) from the external cervical os.
