From: Comparison of muscle activity in the empty-can and full-can testing positions using 18F-FDG PET/CT
Comparison of mean maximum SUVs of the muscles in the empty-can testing position. The middle deltoid exhibited the highest FDG uptake among the six muscles in this position. The middle deltoid, supraspinatus, and subscapularis showed significantly increased muscular activity than the anterior deltoid, posterior deltoid, and infraspinatus. Muscular activity showed a significant increase in the middle deltoid, compared with the supraspinatus (P < 0.05).
