Mediastinal staging is a crucial moment in management of non-small cell lung cancer (NSCLC) patients. In integrated pathways, 18-fluorine fluorodeoxyglucose positron-emission tomography (F-FDG-PET/CT) is an indispensable imaging resource with its peculiarities and its limitations. A critical review of work up protocols would certainly help to standardize procedures with important reflections also on the diagnostic value of this examination. In this regard, new semi-quantitative and semi-qualitative indexes have been proposed with the aim of increasing the accuracy of F-FDG-PET/CT in mediastinal lymph node staging. These latter, such as SUV and SUV indexes, seem to overcome the problem of spatial resolution and discrimination of malignancy by endorsing a new predictive and prognostic role.
纵隔分期是非小细胞肺癌(NSCLC)患者治疗过程中的关键环节。在综合诊疗路径中,18氟氟脱氧葡萄糖正电子发射断层扫描(F-FDG-PET/CT)作为一种不可或缺的影像检查手段,有其独特之处和局限性。对检查方案进行批判性审视无疑有助于规范操作流程,同时也能对该项检查的诊断价值进行重要反思。在这方面,已经提出了新的半定量和半定性指标,旨在提高F-FDG-PET/CT在纵隔淋巴结分期中的准确性。后者,如SUV及SUV相关指标,似乎通过赋予新的预测和预后作用,克服了空间分辨率及恶性肿瘤鉴别方面的问题。
