T1, T2 mapping showed a strong positive correlation with T2*
and T1 was shown to be superior to T2 in the non-invasive assessment of cardiac
iron overload. 30% of the study population had normal T2* values, but low T1
values - an interesting finding.
Figure 4 - 12 patients (30%) out of the total 40 patients showed T1
value below the normal range (<966ms), despite having T2* value in the
normal range (>20ms)
