An accurate assessment of the Tumor Blood Flow can become crucial in deciding the best management for breast cancer patients. In this study, the aim is to compare the model-free blood flow values derived with deconvolution analysis against those derived with a 2-compartment uptake model. Model-free and model based tumor blood flow are well-correlated, but there is a systematic difference in the values obtained.
