Hi Thursday,
I love opinions !!

The needle guided imagery is so that the doctor can put the needle into the correct muscle (scalene) and inject an anesthetic or botox. 1st one for diagnosis second one for treatment sake. I understand it is really difficult to image or even feel your middle scalene so he does the guided by MRI technique to know he is in the right place. hope that answers the question !
Hell of expensive but to me....looking for help it doesn't seem like a lot....only if our dollar was better again!!! LOL

love and hugs,
Victoria
