Chlorine (Cl-) is the most abundant anion in the human body and is involved in many physiological processes. In this work 35Cl images of different pathologies were acquired for the first time in humans. Results were compared to 23Na MRI. 35Cl MRI revealed different signal behavior compared to 23Na MRI. Thus, 35Cl MRI can complement 23Na MRI in clinical research and might enable a better analysis of (patho-)physiological processes in the future.
