In brief: MRI

MRI (magnetic resonance imaging) can detect various tumors, especially if it is used in the context of what is called Multi-Parametric MRI (MPM).
MPM uses various characteristics to help distinguish malignant from benign. Google this term to learn more. Thus, one of the variables that should be used is called DWI (diffusion weighted imaging) and that helps decide if a lesion is malignant or not.
