MRIs in Houston

Hello everyone, I’m hoping someone can help me out. I have a procedure scheduled at the end of February for an exploratory laparoscopy to look for endometriosis. I am due to have a pelvic MRI done before the surgery, however it is needed with vaginal and recital contrast and not many places do that. I was sent to Texas Children’s and they were out of network with my insurance wanted to charge $5k minimum which i cannot afford. Does anyone know any other places that use vaginal/rectal contrast and if so which location? I’m okay with traveling to have this done.
