Multicenter validation of the magnetic resonance t2* technique for segmental and global quantification of myocardial iron
Purpose To assess the transferability of the magnetic resonance imaging (MRI) multislice multiecho T2* technique for global and segmental measurement of iron overload in thalassemia patients. Materials and Methods Multiecho T2* sequences were installed on six MRI scanners. Five healthy subjects (n = 30) were scanned at each site; five thalassemia major (TM) patients were scanned at the reference site and were rescanned locally (n = 25) within 1 month. T2* images were analyzed using previously validated software. Results T2* values of healthy subjects showed intersite homogeneity. On TM patients, for global heart T2* values the correlation coefficient was 0.97, coefficients of variation (CoV…
Prospective Comparison on Cardiac Iron and Liver Iron by MR In Thalassemia Major Patients Treated with Combination Deferipron–Desferrioxamine Versus Deferipron and Desferrioxamine In Monoterapy
Abstract Abstract 5164 Introduction: Using T2* MR a randomised placebo controlled study from Sardinia demonstrated combination therapy with deferiprone and desferrioxamine (DFP+DFO) significantly more effective than DFO in improving myocardial iron. One non-randomised study from Sardinia and one observational study from Greece seem to confirm for DFP+DFO therapy the most rapid clearance of cardiac iron. No data are available in literature about prospective comparisons on cardiac iron and function and liver iron in TM patients treated with DFP+DFO versus DFP and DFO in monotherapy. The aim of this multi-centre study was to assess prospectively in a large clinical setting the efficacy of the …
