Are MRIs these days more advanced? I haven't had one in about 9 years. They are going to measure the CSF flow in my brain with contrast if that helps

The last time I got an MRI for my hydrocephalus was almost 9 years ago. I'm wondering if MRIs are less confined and entrapped. I remember my first MRI I was shaking because it made me have so much anxiety. I have one tomorrow and I'm so nervous for the same nervousness. Any insight? They are going to measure the CSF flow in my brain with contrast if that helps
