Evaluation of MRI Sequences in Hepatic Overload (HEPAT_MR)

Evaluation of MRI Sequences in Hepatic Overload.

MRI, without any contrast injection, allows a non-invasive evaluation and quantification of hepatic overloads, especially iron (liver iron content LIC) and fat (steatosis) overloads, but in certain clinical circumstances, cases require to improve performances. The aim of the study is to add to MRI scans which currently must be performed innovative sequences appropriate for the clinical question to overall appreciate on a varied range of patients their quality, their robustness, their relative performance and, for patients having a biopsy, their accuracy.

Description

Inclusion Criteria:

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Evaluation of the quantification deviations of hepatic iron and fat overloads between the new sequences and the conventional sequences.	Evaluation of the robustness and the relative accuracy, comparison of sequences currently performed in daily clinical practice, of hepatic iron and fat content quantification with non-invasive new abdominal MRI sequences.	18 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Analysis of the accuracy of quantification: of the iron concentration against biochemical, semi-quantitative histological or subtracted iron volume compared to the hepatic volume analysis	Evaluation of the accuracy of these new MRI sequences for hepatic iron and fat quantification, when patients have had in their normal care and management a biopsy or a bleedings subtracted iron volume leading to a desaturation.	18 months
