Is B-Flow USG superior to Color Doppler USG for evaluating blood flow patterns in ovarian torsion?

Objective: Ovarian torsion is an uncommon gynecological emergency that most often affects women of reproductive age. Its signs and symptoms are similar to those of other abdominal conditions, which make its differential diagnosis challenging. Color Doppler (Doppler USG) and B-flow ultrasonography (B-flow USG) are used for the differential diagnosis of ovarian torsion, and in this study, we aimed to evaluate these two techniques, validate B-flow USG as the gold standard non invasive diagnostic tool in the early phase of an ovarian torsion, and show that the B-flow USG is superior to the color Doppler USG.
