Combining Doppler flow imaging with morphologic assessment of the ovary may improve diagnostic accuracy. However, the interpretation of Doppler sonography is inconsistent as a consequence of the dual ovarian blood supply from the uterine artery and the ovarian artery.

A small study in a specialized ultrasound unit found 74.6% accuracy when using sonography to diagnose ovarian torsion. The most diagnostically accurate sonographic signs were abnormal ovarian blood flow and the presence of free fluid. The authors cautioned that ovarian torsion should not be ruled out when typical indicators are absent, especially when clinical history is suggestive of the condition. [26]
