Off to the PET scan this morning. It’s an hour away taking two buses in a part of Buenos Aires I’ve never been. I ate only meat and fat yesterday because carb intake would interfere with the substance they will inject into me in a few hours — radioactive glucose, is my understanding. The glucose will settle into dense tissues, like cancerous cells but also sites of previous infection. Anyway, that will take an hour, then the scan another hour at least. By that time I will have been fasting for 17 hours. Ugh.
