title: Unilateral physiological FDG uptake in teres minor muscle seems well associated with IV tracer injection procedures.
abstract: FDG uptake in teres minor (TM) muscle is often physiologically observed. Here we reviewed data of 578 consecutive patients; TM uptake was observed in 138 patients-in 2 of 68 patients who were administered with FDG via a preexisting line and in 136 of 510 after on-site puncture. In 126 patients with TM uptake without unsuccessful on-site puncture, 78% of TM uptake sites were on the ipsilateral side of injection, 8% on the contralateral side, and 14% on both sides; Cohen κ coefficient was 0.815 when confined to unilateral uptake. Therefore, TM uptake seems well associated with tracer injection procedures.
