Paint brushes from size â0000â to size 12. One feature of paint brushes is the wide variety of sizes. Generally, the size of a paint brush can be identified by a number, the larger the number the bigger the size. Size â0â is a very small brush and the sizes go up to at least size â40â. There are some exceptions to this sizing method.
Drinking coffee before having a PET scan will interfere with the results as caffeine can affect the myocardial uptake, or the amount of tracer used. With intake of caffeine more fluorodeoxyglucose clusters around the heart, making it difficult to take a look into the lesions of the heart.
The last pet I had I was instructed not to eat for 6 hours prior to the scan. When I arrived they tested my blood sugar to make sure it was in normal range. The medicine they give you to drink prior to the scan is some type of glucose concoction. Since cancer tumors intake all the sugar they can, thats what makes the pet show the activity of any cancer tumors as they suck up the glucose and as they say light up the cancer tumors. Lori.
