Yes!
My puzzles on inguinal canal have been settled. Most likely, in many of my cases, the extra peritoneal fat in the canal was confusing me.
Again, your way of creating a Valsava effect is undoubtedly superior, i should try it out.
About 3D/4D, I urgently need gynecology and obs material e.g on mullerian duct anomaly assessment, IUCD localization, fetal cranial-facial anomaly assessment etc.
Contrast enhanced ultrasound is something i wish to know more about.
Thanks
