I have a macroadenoma and claustrophobia. I like you dread every time I have to have an MRI. As you probably know having an MRI is essential for us. I found that taking Ativan helps greatly. It was prescribed to me by my neurosurgeon and to be honest with you, once the Ativan kicks in, I have no idea where I am and no recollection of the MRI. It's been a life saver for me. Without it, I could never have an MRI.
