Combined Real-Time Three-Dimensional Hysterosalpingo-Contrast Sonography with B Mode Hysterosalpingo-Contrast Sonography in the Evaluation of Fallopian Tube Patency in Patients Undergoing Infertility Investigations

Figure 3

The whole right Fallopian tube appeared to be patent when viewed by 4D-HyCoSy; however, the right distal end of the tube was distended with hydrosalpinx (a). A subsequent examination with B mode-HyCoSy confirmed the existence of an obstruction in the Fallopian tube fimbria (b).
