Ultrasonographic Identification and Measurement of the Normal Ovary in Postmenopausal Japanese Women

Abstract
Real-time ultrasonic scanning examinations were performed on 31 postmenopausal Japanese women with no evidence of pathology. Both ovaries were visualized in 25 patients. Only the left ovary was imaged in 5 and only the right one in 1 patient. Ovarian sectional area (OSA) was 1.45 ± 0.61 cm2 in the left-sided ovary and 1.36 ± 0.64 cm2 in the right-sided ovary, with no statistically significant difference. In all 56 ovaries, the OSA was 1.41 ± 0.63 cm2. These normal values in postmenopausal women provide a useful indicator for detection of postmenopausal palpable ovary syndrome.
