Two patients with lung cancer who had undergone stereotactic body radiation therapy (SBRT) exhibited increased F-18 FDG uptake in the chest wall after 6 months and 18 months, respectively, after SBRT. The prescribed dose of 50 Gy to the planning target volume was delivered on 4 consecutive days in each patient. It is important for nuclear medicine physicians to be familiar with F-18 FDG PET/CT findings ascribed to radiation-induced myositis in lung cancer patients treated with SBRT so that an appropriate differential diagnosis can be established.
两名接受立体定向体部放射治疗（SBRT）的肺癌患者，分别在 SBRT 后 6 个月和 18 个月时出现了胸腔壁 F-18 FDG 摄取增加。每位患者的计划靶区处方剂量为 50Gy，连续 4 天给予。对于核医学医师来说，熟悉 SBRT 治疗肺癌患者后因放射诱导性肌炎引起的 F-18 FDG PET/CT 表现非常重要，以便进行适当的鉴别诊断。
