A calculation algorithm has been developped using correlations between
liver iron concentration (LIC) and MR results.
Several sites (Rennes, Angers, Lorient) with different MR equipments
have contributed to get theses results.
The LIC value yielding by the java applet is a statistical estimation.
In few cases there was slight differences between LIC estimated
by MRI and the LIC get by biopsy. It was not possible to say what
was the technique which was right. However, previous series have
shown that biochemical assessment can be less reliant in case of
irregular distribution of iron or in case of associated lesions
such as fibrosis (32).
Artifacts (particularly due to the air in lung bases) could generate
wrong results. Technique used must be appropriate technique
to avoid main errors.
The result given is an estimation and it must be compare to the
patient history and biological results.
