Hi concerneddaughter and welcome to this forum .....
Every doctor/medical facility has their own protocol for how they handle MRI CDs and reports so it is very difficult to say whether you can relax or not.
In my case, the first time I had an MRI showing my acoustic neuroma, the technicians said nothing, gave me nothing, and told me my doctor would have to tell me my results. My next appointment with him was two weeks later. When he did not call me, I falsely assumed I was in the clear for anything abnormal on the MRI. I was completely shocked when I went to the appointment and was told the MRI had shown a 2+ cm acoustic neuroma.
Since that horrible experience, I go back to the imaging facility whenever they say the report will be available (usually 24 hours later) and pick up my own copies of both the CD and the report. In the US, it is legal to do this. Not sure about elsewhere.
You can usually put the CD into your computer and look at it yourself. I would not advise this because there are many blips, white and dark spots that are rather meaningless unless you know which cuts to look at and what to look for.
Many thoughts and prayers. Let us know what the report and/or the doctor says.
