Everything went well, Sam was the life of the waiting room flirting with everyone and shrieking with delight at everyone that would look at him. He was not a fan of sitting still with mom holding his head steady, but the whole thing took less than 10 minutes. I asked if she saw the cysts and she said she didn't.
I then asked if everything looked ok and I got the standard response "I just take the pictures, the radiologist still has to review them".
I don't know why they can't just ease my paranoid fears and tell me there are no big tumors in there! Not that there is any risk of that, but still, it would be reassuring to hear!
Anyway for now we are assuming all is good in that little brain of his and I suppose we'll hear from the doc in a week or so.
