The potential of state-of-the-art MRI at 3T without endorectal coil is presented in this case report article. In both shown cases, MRI was able to improve therapy planning and the surgical outcome clearly.

Diagnostic Radiology, Martha-Maria Hospital Nuernberg, Nuernberg, Germany
This article examines two important clinical cases for a better understanding of potential benefits, but also limitations, of MRI-guided prostate biopsies. All examinations were performed on a 1.5T system (MAGNETOM® Symphony, Siemens Healthcare, Erlangen, Germany).
High b-value image at b = 800 s/mm2.

Contrast-enhanced magnetic resonance (MR) and computed tomography (CT) imaging are currently the standard imaging modalities for pancreatic lesions. Diffusion-weighted imaging (DWI) could prove a non-invasive alternative, since recent advances in scanner technologies, fast pulse sequences and parallel imaging have permitted its use in the abdomen where organ motion and tissue inhomogeneity have long prevented robust diffusion measurements.
