What I would like to add, too, which has not been mentioned before, is that we talk about ultrasound used to diagnose endometriosis, but it's actually quite a difficult thing to do in the community, because it requires a specific skill set with ultrasound. It's much easier to diagnose a gallstone by ultrasound, because you see the stone. With endometriosis, you may see a chocolate cyst, but you may not, so negative scans are often not negative.
At our centre, we often are repeating ultrasounds ourselves, and we're getting outside MRIs reread by our radiologists. These are duplicate amounts of work. They're not remunerated fairly either. We're often asking radiologists at our meetings if they would mind taking a look at an MRI, which has already been reported, but the report is not accurate. There's no standardization of ultrasound reporting in Canada that I'm aware of, or in Quebec for sure, so lots of ultrasound reports we get will just say that there is a normal uterus present, but they lack all the signs that we look for for endometriosis. We have to repeat a lot of work, which is another barrier for patients.
