摘要
In a magnetic resonance method and apparatus to measure a sodium content in tissue in a first slice, a determination of a blood volume in blood vessels in the first slice is made, and an MR acquisition sequence to acquire MR data of a sodium-23 magnetization from the first slice is implemented. A signal proportion of the MR data that originates from the sodium-23 magnetization in blood vessels is calculated based on the determined blood volume in tissue. This signal proportion is subtracted from a total signal of the MR data to obtain a corrected signal that is proportional to the sodium content in tissue. The sodium content in tissue is calculated from the corrected signal.
