Visualization of the endometrium by intrauterine sonography.
Thirty-five women with normal menstrual cycles underwent transvaginal and high-frequency (15- or 20-MHz) intrauterine sonographic examinations for the assessment of the endometrium. Five sonographic patterns of endometrium were recognized by both sonographic techniques, but the pattern visualized differed between techniques in 9 women (26%). The higher resolution of intrauterine sonography provided more detail of the endometrium. Our preliminary experience indicates that high-frequency intrauterine sonography enables more detailed visualization of changes in the endometrium during the menstrual cycle than does transvaginal sonography.
