Fig. 4From: In vivo calibration of the T2* cardiovascular magnetic resonance method at 1.5 T for estimation of cardiac iron in a minipig model of transfusional iron overloadtaken from cardiac septum in connection to the CMR sessions. For each pig, the weekly applied dextran-iron dose is indicated within the figure label as mg/kg/BWSimultaneous follow up of cardiac R2* and chemical CIC by EMBs during iron loading. Cardiac T2* (a) and chemical CIC (b) were followed up with 1–3 months intervals during dextran-iron loading in 11 minipigs for up to 15 months. Pigs 2, 4, 6, 7 died due to biopsy-related complications after 6.5, 5, 2 and 2 months of iron loading, respectively. In pig 4, parallel 5-months results of CIC and R2* were not available. Chemical CIC was assessed by ICP in EMBs, Back to article page
