Why is the FerriScan sequence slow and full of breathing artefact?
To obtain optimal sensitivity and specificity over a large range of liver iron concentrations the fundamental 1/T2 value needs to be measured rather than 1/T1 or 1/T2*. This necessitates a long TR to minimise T1 effects and prevents the use of a breath-hold scan. As a result, modest breathing artefacts are expected and are compensated for during the FerriScan Analysis.
