Fig. 3B —46-year-old man with adenocarcinoma in right lower lobe and
metastasis in right paratracheal lymph node, which was predicted by integrated
PET/CT but not by helical dynamic CT. Transverse conventional (5.0-mm section
thickness) enhanced CT scan (A) shows lymph nodes in right paratracheal
area (arrow) with short-axis diameter of 7 mm, representing benignity
with CT size criteria for malignant nodes. Integrated PET/CT image (B)
shows high 18F-FDG uptake with maximum standardized uptake value of
8.0 in right paratracheal lymph node (arrow).
