Track density imaging of the prostate with isotropic 300 μm resolution was implemented at 3T. Imaging time was nearly identical to a clinical diffusion-weighted acquisition. A total of 19 patients have been imaged to date. At least two examples are seen of tumor interrupting tracks within the central gland. Further work will include pathologic validation to assess the physical basis of observed tracks.
