Liver iron overload assessment by MRI R2* relaxometry in ...

CONCLUSION: MRI is a useful tool to quantify iron overload non-invasively. In cases where a liver biopsy is hazardous MRI can easily be used to obtain reliable, quantitative information about the initial LIC. Quantification by MRI could also be used for follow up of the iron content during depletion treatment by phlebotomy or iron chelation.

The calculator will fit the data points, tell you the T2*, and compute the liver iron concentration. Report the T2* value, the liver iron concentration, and reference the article by Wood et al. in Blood 2005; 106: 1460-1465. To perform the analysis, draw an ROI around the liver, excludng as much portal vein and IVC as you can.

Guidelines for quantifying iron overload | Hematology ...

MRI can quantify a parameter called "T2*", which is an indicator of the amount of iron in the liver and myocardium. The smaller the T2*, the greater then iron deposition. The reciprocal of T2* is referred to as R2*, i.e. R2* = 1/T2*. Liver and myocardial iron concentration is directly proportional to R2*.
