Hello everyone I've been "lurking" on here for a couple of weeks but decided it was time I stopped hiding. I also have some questions that I haven't been able to find the answer to. The cause of my one-sided pulsatile tinnitus is being investigated on the NHS, my GP referred me as she suspected Menieres. I have an appointment for a scan in a few weeks - "MRI internal auditory meatus both". Although the injection of dye is mentioned as a possibility in the covering letter, I'm assuming that because the title of the scan doesn't say "with contrast" that I'm not having that. Am I right? Does that mean that all this will achieve is to exclude an acoustic neuroma? If the problem was caused by an artery, would that show up? Sorry for asking so many questions straight away, and thanks in advance for any help.
