We evaluated the whole body distribution of 2-deoxy-2-[18F]fluoro-D-glucose (18F-FDG) in seven beagle dogs using positron emission tomography/computed tomography. The mean and maximum standard uptake values (SUV) for various tissues were computed. The SUV of the aortic blood pool was 0.65 +/- 0.19. Moderate uptake was present in brain (3.40 +/- 1.01). Mild uptake was present in orbital muscles, soft palate, laryngeal and pharyngeal region, mandibular salivary gland, myocardium, liver, pancreas, kidney, and intestine. 18F-FDG uptake would be normally higher in these tissues because of normal physiologic activity. Mean and maximum SUV values of the eye, skeletal muscle, bone tissue, spleen, adrenal gland, stomach, tongue, gall bladder, and lung were similar to or lower than that of the aortic blood pool. These data provide a normal baseline for comparing pathologic 18F-FDG uptake.

FS and Nasopore were equally successful in achieving hemostasis and patient satisfaction after FESS. However, our results suggest that differential mucosal healing patterns may be induced by alternative absorbable hemostatic materials. FS-treated sides showed more optimal healing patterns than Nasopore-packed sides.

LVI could be an indicator of biological aggressiveness and may be a reliable prognostic factor for node-negative gastric cancer. LVI should be considered in postoperative management of gastric cancer.
