Hi Steve
When I scan the male inguinal canal/spermatic cord, I employ a “coughing maneuver”. when there is a sizeable hernia, it is easy to diagnose. I have noticed certain structures that respond (by moving somehow)even when there is no “obvious hernia” what do you think these structures/contents could be?
Again, which resources, e.g text books have you used and have helpful content on 3D/4D & contrast enhanced ultrasound imaging?
