Free breathing technique for Cardiac T2* measurements could be a useful technique in non-cooperative patients. No study guarantees that this technique will provide the same results as that of the standard breath-hold. We compared the 2 techniques in 2 different fitting models, Simple Mono Exponential (SME) and Offset models. The study was done with 14 normal, and 54 Thalassemia volunteers. The results showed that Offset model exhibited 3 false positives with breath-hold technique in normal group. However in term of clinical applications, both data acquisition techniques and fitting models can separate iron overload to the non iron overload groups equally.
