Renal imaging using MRI is crucial but not available to many institutions because until now it relied in high-end systems working at high or ultra high field strengths. As an alternative, a low-field portable MR-system which can achieve similar resolutions like a small animal system can provide images with the demanded resolution. Purpose of this work is an initial comparison of the image quality of an acquisition with the low field system to the state of the art methods. In all images a distinction between the different tissue compartments is possible. In conclusion, high resolution imaging of the kidney need not necessarily be performed on high field systems. The portable MR system reaches a sufficient resolution for the distinction of different renal compartments as well as the identification of an inner structure of the renal cortex.
