A method for generating a map of a region of a patients body containing one or more lesions that provides information about MR diffusion properties and/or level of suspicion of malignancy. Performing at least one first scan of the region with an MRI apparatus set to a first b value to obtain a first matrix of pixel or voxel values, int(B1) performing at least one second scan of the region with the apparatus set to a second b value to obtain a second matrix of pixel or voxel intensity values, int(B2) deriving a first computed value that is a monotonic function of ln(int(B1)/int(B2) multiplying each computed value by a value proportional to int (B1) to obtain a second computed value and producing a representation of all the second computed values that is indicative of the likelihood that one or more of the lesions are malignant.
