Our purpose is to investigate tumor biology of lung
SUVmax was significantly greater in the solid subtype and poorly differentiated tumor when compared to other subtypes or differentiations. f tended to increase as tumor differentiation changed more poorly, whereas D and D * showed a trend of decrease in poorly differentiated tumors. Tumor size, the size of the solid portion within the tumor, and ADC showed significant correlation with extent of tumor invasion. SUVmax showed significant correlation with tumor cellularity.
