F-fluorodeoxyglucose (F-FDG) is a radiopharmaceutical that exhibits glucose-like kinetics and is used in positron emission tomography (PET). F-FDG is used for cancer diagnosis in clinical practice. However, F-FDG uptake is also observed in normal organs, such as the brain, liver, and heart, with high glucose consumption. Moreover, F-FDG uptake is also observed in muscles, where its accumulation and radioactivity reflect muscle activity. Dystonia is characterized by excessive muscle movement. Recently, F-FDG and technetium-99m-methoxyisobutyl isocyanide ([99mTc]MIBI) have been used for the diagnosis and botulinum toxin therapy evaluation of dystonia. This review aimed to summarize the utility of F-FDG-PET for the evaluation of muscle activity and diagnosis of muscle diseases such as dystonia, polymyositis, dermatomyositis, and polymyalgia rheumatica.
氟脱氧葡萄糖（F-FDG）是一种具有类似葡萄糖动力学的放射性药物，用于正电子发射断层扫描（PET）。F-FDG在临床实践中用于癌症诊断。然而，在正常器官如大脑、肝脏和心脏中也观察到F-FDG摄取，这些器官葡萄糖消耗较高。此外，在肌肉中也观察到F-FDG摄取，其在肌肉中的积聚和放射性反映了肌肉活动。肌张力障碍的特征是肌肉过度运动。最近，F-FDG和锝-99m-甲氧基异丁基异腈（[99mTc]MIBI）已用于肌张力障碍的诊断和肉毒杆菌毒素治疗评估。本综述旨在总结F-FDG-PET在评估肌肉活动以及诊断肌张力障碍、多发性肌炎、皮肌炎和风湿性多肌痛等肌肉疾病方面的应用。
