Hi, thanks for your answer!
I'm Ana Maria's daughter
The proceidure we called "angio-MRI", we don't really know how it is called in english, it consists of an MRI that shows the veins and possible stenosis. The only catheter that was used was inserted in the arm to get the contrast liquid in. I don't know if this is what is called an MRV.
This first proceidure was done to see if we should go for a venography/venogram or not. Doctors are still taking baby steps on the CCSVI detection/treatment so they thought it would be better to start with a less invasive exam. We were lucky since my mother found a young doctor (radiologist) which is really eager to study this and learn about this
I also heard we have one of the best interventional radiology teams in the country
So now, since they found a stenosis, which was vital to decide if they would do a venography or not, they decided that my mother should do it. When they perform this proceidure they will also use the balloon technique on the stenosis they find. We just want to make sure that they check the azygos aswell because we read on several articles and papers and you also said it, that the azygos can only be properly observated by doing a venography.
So in spite of not wanting to get our hopes up, since the real results can only be seen after the "liberation" proceidure has been done, we are happy that we managed to get a venography
I'm glad you liked Portugal!
