In vivo magnetization transfer of liver at 3T

Magnetization transfer (MT) imaging of liver has been shown to be of clinical diagnostic value but can be hindered by breathing artifacts. Further, in vivo liver MTR values have not been fully characterized at 3T. A breath-hold segmented MT strategy was used to acquire MT ratio (MTR) maps of the liver with decreased imaging time and no breathing artifacts. The average normal liver MTR value from five volunteers was 18.5% 2.8%. This value may more accurately reflect the MTR values for human liver at 3T using a sequence that acquires high-quality, quantitative MTR maps of the liver.
