MRI literature shows that it is possible to increase image reconstruction quality by removing coils that cause majority of the streaking artifacts. We introduce to measure the coil quality based on mutual information between a reference and each coil image. Specifically we apply this technique to DCE-MRI reconstruction from under-sampled radial stack of stars trajectory for kidney imaging and calculate mutual dependence between a dynamic image from each coil and a reference image to assess coil contribution to reconstruction. Experiments show mutual dependence based coil selection reduces artifacts and increases reconstructed image SNR by $$$16.84\%$$$ using $$$1/3$$$ of the coils.
