Big OOPS- hysterogram vs hysteroscopy vs HSG

Okay- I was thinking "hysteroscopy" and seeing and writing "hysterogram." I am so sorry to increase confusion! Hysteroscopy is the test with the camera and no x-ray. I believe hysterogram is a look at the uterus with an x-ray and dye, not the tubes (the "hystero-"=uterus and "-salping"=fallopian tubes in the word "hysterosalginogram" or HSG in medical-ese). I would double-check as to why they are doing a hysterogram and not a HSG (which I think may be more comprehensive) if that is indeed what they are planning to do. I apologize again for making things more confusing.
