@gloriajean On 7/26 I had a PET CT scan. I am not a fan of enclosed places, either. The first part took about 30 minutes of laying perfectly still, except for my eyeballs and breathing. They even used a device to keep my arms in place [to me it felt like a straight jacket!]. I meditated, did Tai Chi in my mind, did some Zentangle in my mind. Hope to not have to repeat it any time soon again.
