Description:

Currently, static scans are commonly used for Positron Emission Tomography/Computed Tomography (PET/CT) examination in the literature. Accordingly, functional images of 2-[18F]fluoro-2-deoxy-glucose (18F-FDG) Positron Emission Tomography/Computed Tomography (PET/CT) with dynamic scans can be more sensitive to detect metastatic lymph node, since the introduction of temporal dynamic variables would provide more imaging quantification than conventional static scans. The purpose of this study is to provide the dynamic 18F-FDG PET/CT imaging for esophageal squamous cell carcinoma (ESCC) patient to quantify the difference between malignant lymph nodes (MLN) and benign lymph nodes (BLN).
