In this study a new sign to evaluate the evolution of pregnancy is described: the trophoblastic thickness at the embryonic implantation site.

Contribution of transvaginal sonography to the evaluation of benign cervical conditions.

Purpose: We evaluated the role of transvaginal sonography in imaging the normal cervix and its benign changes.
