PET scan next week
Just got a call to say that my PET scan will be on Monday morning 9 am. I fast for five hours beforehand (so that I'm ready to go really slow for a few hours...). This scan is to determine whether the residual mass revealed in my most recent CT scan is still active or is merely scar tissue. I get an injection of radioactive glucose (sugar) and sit very still for an hour. Sugar is picked up by cells that have been active (which is why I sit very still - so that as little as possible goes into other muscles), particularly the brain and active tumour cells. I then lie inside a large tube that functions as a 3D Geiger counter, measuring where radiation is coming from (i.e. which cells have been picking up the glucose). I probably won't get the results for at least a couple of days. I'll post an update here as soon as I know.
In other news, yesterday I went to my first session of speech therapy proper and have been given a variety of amusing sounds to practice. I would have been really good at being a speech therapist before I lost my voice - I used to love practising silly noises.
