Objective
To summarize the research progress of magnetic resonance quantitative technique in the iron overload of the abdominal parenchyma organ.
Methods
By reviewing the related literatures domesticly and abroad, the present status and progress of abdominal magnetic resonance quantitative technique and other examinations in the study of iron overload were analyzed.
Results
MRI multi-sequence examination technique had changed the research model of iron overload in different organs, and had important clinical significance in imaging diagnosis of abdominal parenchyma organ damage. so far, many techniques of MRI had been used in detection of iron overload, which included signal intensity measurements(including signal intensity ratio and signal intensity difference of positive and negative phases), T2/R2 measurements, T2*/R2* measurements, Dixon and its derivatization, ultrashort echo time technique and susceptibility weighted imaging (including conventional susceptibility weighted imaging and quantitative magnetic sensitive imaging).
Conclusion
Magnetic resonance quantitative examination technique is expected to be the first choice for detection of hepatic iron overload, and can improve the early detection rate of iron overload pancreatic damage.
