Positron emission tomography (PET)-computed tomography (CT) is a useful device in identifying musculoskeletal lesions that require biopsy. It can be used to localize the primary lesion, identify a site to biopsy, and evaluate metastatic lesions that require follow-up biopsies. Not all malignant tumors have hypermetabolic activity, and there are many benign lesions and physiologic processes that do have increased F-18 fluorodeoxyglucose uptake. Knowledge of these issues is important when reviewing PET-CT and directing subsequent musculoskeletal biopsies.
正电子发射断层扫描（PET）-计算机断层扫描（CT）是一种用于识别需要活检的肌肉骨骼病变的有用设备。它可用于定位原发性病变、确定活检部位，并评估需要后续活检的转移性病变。并非所有恶性肿瘤都具有高代谢活性，而且有许多良性病变和生理过程确实会出现F-18氟脱氧葡萄糖摄取增加的情况。在解读PET-CT结果并指导后续肌肉骨骼活检时，了解这些问题很重要。
