Simultaneously acquired diffusion weighted imaging and 18-fluorodeoxyglucose(FDG)-PET are employed to explore the relationship between glucose avidity, diffusion, and perfusion in breast cancer. Intravoxel incoherent motion metrics are calculated and combined with correlated FDG-PET standard uptake values (SUV) for all voxels in 16 histopathologically proven breast cancer lesions. Two-dimensional histograms and Pearsons correlations are used to define three lesion types. Each lesions voxels are separated into three groups according to their SUV, diffusion, and perfusion fraction. The results yield insight into the heterogeneity of the tumor microenvironment and show significant correlations with estrogen receptor expression and a cellular proliferation marker (Ki-67).
