2.1.1\ Method

The patient should void the urinary bladder. The probe is placed in the vagina, the direction of sound beam through the middle longitudinal section of the uterus.

2.1.2\ Section Structure

The left part toward the abdominal wall is the uterus base, the down part next to the probe is the anterior uterus wall, and the right part toward post ridge is the cervix. The hyperechogenicity line locating the uterus center is the uterus cavity line.

2.1.3\ Measuring Method and Normal

Measuring length diameter and anteroposterior diameter of the uterus by this section, the mea-

surement of length diameter from the surface of the uterus base to the endostoma of the cervix, the normal value is 5–7 cm; the measurement of anteroposterior is the maximum AP distance which is vertical of upper-down diameter, the normal value of which is 3–4 cm.

2.1.4\ The Clinical Application Value

The transvaginal longitudinal section is the most important section to understand whether the size and shape of the uterus is normal. Endometrium image shown by transvaginal scan is clearer than that by the transabdominal scan, so this section is also the most important one to show the endometrium and to obtain intracavity information.
