Studying whether three-dimensional transrectal ultrasonography can aid the diagnosis of polycystic ovary syndrome in young women.
MedWire News: Three-dimensional transrectal ultrasonography (3D-TRS) can refine the diagnosis of polycystic ovary syndrome (PCOS) in adolescent women, Chinese research has revealed.
A team from Shandong University Qilu Hospital used 3D-TRS to evaluate 75 young women with ultrasonically diagnosed polycystic ovaries who were amenorrheic, oligomenorrheic, or asymptomatic, and 25 staff volunteers.
Serum biochemical markers of PCOS were assayed during the early follicular phase of the cycle in menstruating patients and control participants, and on a randomly selected day in amenorrheic patients.
A diagnosis of PCOS was verified in 45 patients, with the remaining 30 having only polycystic ovaries but no clinical or biochemical evidence of PCOS.
Ovarian stromal area was significantly greater among patients with PCOS or polycystic ovaries alone compared with the volunteers, at 2.68 mm2 versus 1.25 and 1.64 mm2, respectively.
The same was true for the ratio of stromal to total area (S/A), at a corresponding 0.51 versus 0.32 and 0.27, respectively, and this measure correlated most significantly with androgen levels among the hormones studied.
Li Sun and Qingzhao Fu explain that the 3D-TRS procedure is similar to 3D transvaginal sonography.
They conclude: “The precision of the diagnosis of PCOS is greater with 3D-TRS, and 3D-TRS allows for the evaluation of virgin patients.”
