Imaging Intravenous Iron

The aim of this study is to track where the iron goes in different tissues in the hours, days and weeks after an intravenous iron infusion. We will track iron in tissues using MRI relaxometry parameters R1/R2/R2* which are well established as accurate indicators of tissue iron content.

Inclusion Criteria:Participant is willing and able to give informed consent for participation in the study.Aged 18 years or above.Anaemia (haemoglobin less than 120g/L for women and less than 130g/L for men) and/or confirmed iron deficiency (ferritin less than 100mcg/L and/or transferrin saturation less than 20%).Scheduled to receive intravenous iron (Ferinject) for correction of iron deficiency.Exclusion Criteria:Any MRI incompatible implants (e.g. cardiac, neuro, ocular implants, surgical clips, aneurysm clips, shrapnel/bullets)Pregnant or lactating participantAcute decompensated heart failureUnstable clinical statusAny other medical conditions which would influence the reliability of the study results determined by the investigators.Any other contraindication to MRI to be confirmed by the qualified MRI operator, e.g. tattoos containing traces of metal.
