Is an MRI helpful?

Hi, I am wondering how important it is to have an MRI done? I am planning for my second surgery by a specialist after my first surgery (only 4 months ago) did nothing, in fact I feel much worse. I’m really, really hoping that having an endo specialist do my surgery this time will work. But she never suggested an MRI and I am worried she might miss something. I’ve had all the other scans but no doctor has ever suggested an MRI. Are they even helpful? Should I push to have one done? Interested in other people’s experiences with this.
