Sedated MRI/renal ultrasound/blood tests

Niko's tests are a go.  My sweet boy is being sedated as we speak.  Luke called from the hospital to say that all was well and Niko was doing really, really well.  I could cry, I'm so happy and relived.  They're looking to see if something in his brain is affecting his speech delays. Do I want them to find something? Do I want it to be clear? I don't even know what to pray for!  All I know is that we're heading in the right direction, and I'm thankful for that.
