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.
