Never go by radiologist report. Countless times I wondered what the heck they were thinking (or not) so I never wait for report, just take home cd and look myself. They're radiologists not neurologists.
Go back where you had scan done, take it home on cd & start learning how to view them. A viewer is always included on cd (for me anyway) but I like Onis out of all i've tried cause it allows you to import all your cd's and compare. Priceless & free!
