宫颈癌是女性最常见的恶性肿瘤之一。正电子发射断层显像(positron emission tomography,PET)及PET/CT能够同时提供肿瘤的解剖结构和代谢图像,不受局部解剖位置改变的影响,具有较高的特异度,并且能够通过18-氟代脱氧葡萄糖(18F-FDG)标准摄取值辅助评估肿瘤转移的可能性,因此其对宫颈癌患者淋巴结和远处转移的检查效果优于传统的影像学检查,并且有助于早期发现复发肿瘤、评估预后和制定治疗方案。但18F-FDG标准摄取值的临床使用价值、PET及PET/CT检查能否代替传统的检查方式或临床分期还需大样本前瞻性研究证实。
Cervical cancer is one of the most common malignancies in women. Positron emission tomography (PET) and PET / CT are capable of providing both anatomical structures and metabolic images of the tumor at the same time without the influence of changes in the local anatomical position, have high specificity, and can be detected by 18-fluoro The standard ingestion of deoxyglucose (18F-FDG) assists in assessing the possibility of tumor metastasis. Therefore, the detection of lymph node and distant metastasis in cervical cancer patients is superior to traditional imaging examination and helps to find early recurrence of tumor, Assess the prognosis and develop treatment options. However, 18F-FDG standard value of clinical value, PET and PET / CT examination can replace the traditional method of examination or clinical staging needs a large sample of prospective studies confirmed.
