Hi Luna,
Take my word I have had many MRI's over the yrs. I also have TLE with absence, cp sz., and simple partial sz. Having an MRI made a world of difference in finding what caused my sz. You will hear a lot of banging going on but that's just the machine getting the pictures and if you like the medical field you can see the detail of your pictures like you won't believe. Also if the Dr. gives you a shot which will make you hot for a couple of minutes that will show even more detail. The shot is a type of dye going through your system to show more detail. I never have been chlostropobic (sp?) but take my word the test will be well worth it and they often play music to help relax you when your having this test done. Here's wishing you well and May God Bless You!
