Hello Kerri
I handle the PET/CT without difficulty because they made me more confortable with my leg positioning, it is less confining than MRI's and does not last as long. The MRI was difficult for me. It was extremely difficult for me to remain perfectly still for 45 min and I caused the scan to have somew bluring in spots where they did not start over. I did not know about taking a sedative but if I ever have another I will take something.
