In this study, we evaluate the diffusion and perfusion characteristics of pulmonary invasive fungal infections (IFI), which were calculated using the intravoxel incoherent motion (IVIM) model. We found that a low perfusion fraction f might be a noninvasive imaging biomarker for unfavorable response.
