Analogous to laboratory evaluation, some organizations recommend imaging studies only for women with moderate or severe hirsutism (mFG >15), [62] However, many clinicians recommend pelvic ultrasonography for all women seeking treatment for signs of increased androgens since this technology is noninvasive, relatively inexpensive, and very accurate for diagnosing both PCOS and ovarian neoplasms. [64]

The diagnosis of PCOS is made in women with hirsutism when at least 1 ovary is found to have 12 or more follicles < 10 mm in diameter, assuming other pathology is excluded. [27] The presence of a large, complex ovarian cyst can indicate the presence of an androgen-secreting ovarian tumor. [70]
