An analyzer‐based X‐ray phase contrast imaging (ABI) system with an asymmetrical crystal set‐up was mounted at Elettra's SYRMEP beamline. It was the first time that this set‐up was implemented at Elettra. Advantages and disadvantages of such a set‐up were exploited with quantitative and qualitative studies. For quantitative studies a simple hollow tube and strands were used as samples. Qualitative studies were developed using this technique with ox brain tissue, which has never been previously examined in this manner. Minute details were found in the ABIs and in the diffraction enhanced images. This could indicate the possibility of using these techniques with computerized tomography in the future as an auxiliary method in diagnosing brain illnesses such as Alzheimer and Creutzfeldt‐Jacob disease. Propagation‐based X‐ray phase contrast imaging was also qualitatively exploited and compared with ABI using a Loxosceles gaucho spider as a sample.
