Optimal Scan Time of 18F-FDG PET in Identifying Therapeutic Efficacy Secondary to Radiofrequency Ablation of Lung Cancer: Case Report.

ABSTRACT: Positron emission tomography (PET)/computed tomography (CT)-guided radiofrequency ablation (RFA) has become a major treatment approach for small tumors. Identifying this quantitative dynamic 18F-2-fluoro-2-deoxy-d-glucose (18F-FDG) activity at the primary lesion can minimize misdiagnosis and allow an opportunity to reintervene. Here, we report 3 patients with nonsmall cell lung cancer (NSCLC) who underwent the ablative therapy with split-dose 18F-FDG fused PET/CT scans for early identification of residual tumors and follow-up evaluation of treatment. Our results indicate that reliable post-RFA imaging follow-up is critical in fast and efficient assessment of complete tumor resection in patients experienced the ablation procedure.
