报告简介：
Liver iron concentration (LIC) quantification is indispensable for the diagnosis and monitoring of treatment for patients undergoing chronic blood transfusion. Although the LIC can be measured using R2 and R2* methods, the accuracy and precision is still limited, especially for high iron concentration. Quantitative susceptibility mapping (QSM) has been shown to be effective in quantifying cerebral iron content. In this study, we show a method which extends QSM from the brain to the liver. Specifically, we quantify the iron concentration in the liver tissue by measuring the apparent susceptibility of the vessels in the liver. Simulation, phantom and in vivo studies show that much higher accuracy and precision in measuring LIC can be achieved.
