Abstract

SUMMARY


Objective: MRI T2* is an accurate non-invasive method for assessing organ iron overload. This study evaluated the correlation between serum ferritin and iron overload of liver, spleen and heart in β - thalassaemia major patients by MRI T2* method.
Materials-Methods: A cross-section, descriptive study was designed. We used MRI-T2* to evaluated the correlation between
serum ferritin and iron overload of liver, spleen and heart in 24 thalassaemia major patients admitted in ChoRay hospital from
10/2013 to 1/2014.
Results: Moderate negative correlation between serum ferritin and liver, spleen MRI T2* relaxation time (r = 0,57 and 0,755) and a weak negative correlation between serum ferritin and heart MRI T2* relaxation time (r = 0,303). Liver and heart MRI T2* readings were poorly correlated (r = 0, 28).
Conclusion: MRI T2* is useful to evaluate the iron overload status in β thalassemia patients.
