目的:PET-CT可以通过18F-FDG在头颈部吸收的改变来确定头颈部肿瘤或者头颈部第二原发肿瘤。然而,生理和异常病变都可以使18F-FDG吸收增加,因此,我们评估18F-FDG在头颈部的吸收来判断示踪剂异常吸收的临床价值。方法:经机构审查委员会批准,我们对新诊断的314例头颈部鳞状细胞癌(HNSCC)患者进行前瞻性研究,并且征得所有参与
OBJECTIVE: PET-CT can identify head and neck or head and neck second primary tumors through changes in 18F-FDG absorption in the head and neck. However, physiological and abnormal lesions can increase 18F-FDG absorption, therefore, we evaluate 18F-FDG absorption in the head and neck to determine the clinical value of tracer Abnormal Absorption. METHODS: With the approval of the Institutional Review Board, we conducted a prospective study of 314 newly diagnosed patients with head and neck squamous cell carcinoma (HNSCC) and obtained all participation
