FIGURE 4. Correlation was seen between FDG T/N and degree of cell differentiation in adenocarcinoma of lung. However, in 201Tl ER and DR, no significant difference was found between bronchioloalveolar carcinomas and poorly differentiated adenocarcinomas. In lung adenocarcinoma, FDG uptake, but not 201Tl uptake, reflects degree of cell differentiation. BAC = bronchioloalveolar carcinoma; Well = well-differentiated adenocarcinoma; Mod. = moderately differentiated adenocarcinoma; Poorly = poorly differentiated adenocarcinoma.
