What is the primary diagnostic method for ovarian torsion?

The primary diagnostic method for ovarian torsion is pelvic ultrasound (US Pelvis). This imaging technique is preferred due to its ability to rapidly assess blood flow to the ovaries and identify any abnormalities. Ultrasound is non-invasive, does not involve radiation, and is particularly effective in evaluating the reproductive organs.

In cases of suspected ovarian torsion, the ultrasound can demonstrate characteristic findings such as an enlarged, edematous ovary with reduced or absent blood flow on Doppler imaging. These findings help confirm the diagnosis and guide immediate management to prevent complications, such as loss of the affected ovary.

Other diagnostic methods have limitations when it comes to ovarian torsion. For instance, a CT scan of the abdomen and pelvis may provide additional information about the abdominal organs but is not the first-line choice due to its exposure to radiation and lesser sensitivity for ovarian issues. Urinalysis primarily assesses the urinary system and would not directly indicate a diagnosis of ovarian torsion. Endoscopy is invasive and not suitable for the acute diagnosis of ovarian torsion, as it involves direct visualization of the internal organs rather than imaging them. Thus, pelvic ultrasound is the preferred initial diagnostic tool in suspected cases of ovarian torsion.
