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.
My PET scan instructions were for a low carb diet beginning at dinner the night before the scan, and I was to have NO food or drink for 4 hours before the scan. Also, no strenuous exercise or accupuncture for 12 hours prior to the scan. You can have a small amount of water in the 4 hours before the scan. Make sure you don't wear clothing with zippers or other metal (I wore sweats).
