Study Notes

Normal Uterus

Scan the uterine cervix in different projections to note any abnormal variations in size or shape.
After pregnancy, the cervix may be asymmetrical, and the uterus increases in size, becoming more rounded.
Record uterine dimensions; a longitudinal scan shows a small amount of fluid in the cul-de-sac, which is normal after ovulation or menstruation.

Postmenopausal Uterus

The uterus is smaller and appears homogeneous, with the endometrial cavity not visible.

Normal Ovaries

Ovaries are paired female gonads, firm and ovoid in shape, measuring approximately 1.5-3.0 cm × 1.5-3.0 cm × 1.0-2.0 cm (corresponding to a volume of 1.2-9.4 cm3).
Ovaries lie within the ovarian fossa on the posterior wall of the true pelvis and form part of the adnexa.
Normally, ovaries contain anechoic spaces (ovarian follicles) and should not be found in front of the uterus.
In postmenopausal women, ovaries are small and may be difficult to identify.

Ovarian Follicles

Follicles appear as cysts with an echogenic space within or around the surface of the ovary, best seen with low gain settings.
Follicles can be up to 2.5 cm in diameter and may be physiological, changing or disappearing during the menstrual cycle.
Follicular cysts should regress, and nonfunctional cysts should not change in size.

Scanning Techniques

Use varied gain settings to obtain the best images.
Rotate the patient to see if the ovary is fixed by adhesions and note whether it is significantly enlarged.
Use slow, continuous scans to see the relationship of the pelvic organs.
