摘要
The present disclosure relates to a medical analysis system (111) for processing magnetic resonance imaging, MRI, data (170) from a target volume (208) in a subject (218). The system (111) comprises a memory (107) for storing machine executable instructions; and a processor (103) for controlling the system (111), wherein execution of the machine executable instructions causes the processor (103) to: determine from the MRI data (103) chemical exchange saturation transfer, CEST, voxel values corresponding to a transfer of saturation between a predefined pool of protons and water protons, the pool of protons having a predefined chemical shift; and weight the CEST values in order to distinguish CEST values of fluid-rich tissues (507) from CEST values of solid tissues (505) in the target volume (208), wherein the fluid-rich tissue comprises an amount of fluid higher than a predefined minimum amount of fluid.
