In recent years, new and promising approaches have emerged in the field of MRI imaging of the prostate. These approaches usually aim to visualise the so-called "microstructures" of the tissue and are intended to offer greater accuracy in the diagnosis of prostate cancer than the current mpMRI examination. To this end, mathematical microstructure models are calculated that determine the proportional presence of histological substructures in specific MRI volumes. Additional new MRI sequences that are not routinely recorded are required to calculate the microstructure models. In order to further investigate the possibilities of these new MRI sequences, this study will compare different mathematical models. In addition, a histopathological examination of the tissue will be performed.
