Predicting onset of labor from echogenicity of the cervical gland area on vaginal ultrasonography at term.

Background And Aim: On vaginal ultrasonography, cervical gland area (CGA) gradually disappears with advancing gestation. This is attributed in part to the echogenicity of the CGA becoming equal to that of the cervical stroma. The present study aimed to assess the usefulness of echogenicity in the CGA at term for predicting the time of spontaneous onset of labor.
