Iron overload is a common complication of transfusion dependent patients. Magnetic resonance imaging can be used for quantitative detection of iron deposition in transfusion dependent patients. A total intake of iron for transfusion was evaluated based on the mDIXON-Quant and 3D-FFE sequence respectively. Because the mdixon-quant can avoid the effect of fat on the iron overload evaluation, the mDIXON-Quant sequence can more accurately quantify iron deposition in liver and pancreas than 3D-FFE sequence. The quantitative application of mDIXON-Quant in detection of iron deposition in patients can provide reliable basis for iron chelation therapy in clinic.
