Same case as in Fig. 3; upon her second visit (24wks), the following data were conducted Acervical length 2.9 cm B EI of the whole cervix is still 2 (moderately soft). C strain at the internal os and external os are still noted to be high 0.657 and 0.546, respectively. D EI of the internal os is upgraded to 3 (very soft). E EI of the external os is 2 (moderately soft). Upon following up the patient, she delivered her fetus at 31 weeks 2 days
