In this study, the condition of the kidney transplant in adults is to be assessed non-invasively using Multispectral Optoacoustic Tomography and Ultrasound Localization Microscopy (ULM). ULM imaging can be performed in a 2-dimensional and a 3-dimensional way (2D and 3D ULM). Therefore, "ULM" in the following texts and measures will refer to 2D and 3D ULM.
New, non-invasive markers that allow conclusions to be drawn about the condition of the transplant should reduce the need for invasive diagnostic procedures in the future.

indication for biopsy set in clinical routine
minimum 18 years of age
