Has your doctor ordered you to have a PET scan? He or she may have also told you about this special injection called `Gallium Ga 68 Dotatate`. Hearing this name may sound a little complicated, and you may even be a little scared. But there is no reason to panic. Today we will talk about this very simply, in a way that you can understand.
What exactly is Gallium Ga 68 Dopate?
Simply put, this is a radiopharmaceutical . Now, don't be scared by the word "radioactive." This is a very small, controlled, safe dose of radioactivity. More precisely, it's a "tracer," a marker, that's used to find specific types of cells in your body.
This drug is used in conjunction with a PET scan (Positron Emission Tomography scan) . Its main function is to find out if there are any Neuroendocrine tumors (NETs) in the body, and if so, where they are. When this drug enters the body, it goes to the cells that contain the NETs and sticks to them. Then, when you look at it with the PET scan machine, those areas are clearly visible. It's like shining a small torch in a dark room to find something.
Things you need to tell your doctor before using this medicine
