Abstract

ABSCTRACT: BACKGROUND: Iron overload is a major concern in blood transfusion dependent beta-thalassemic patient and it is a major cause of cardiac dysfunction. Magnetic resonance imaging T2* has a vital role in liver and cardiac iron deposition and assessment of its severity OBJECTIVE: To highlight the role of MRI T2* in assessment of liver and cardiac iron deposition and assessment of other methods of liver and cardiac iron concentration estimation. PATIENTS AND METHODS: This cross sectional prospective study had been conducted at the MRI unit of Al-Imamain AL-Khadimain medical city, Baghdad/ Iraq, from December 2015 to December 2016. One hundred, blood transfusion dependent beta-thalassemia major patients had been examined by MRI using T2* images to assess its value which had been changed to liver iron concentration and cardiac iron concentration by using a MEDIS software program. RESULTS: One hundred patients (56 male and 44 female) of transfusion dependent beta-thalassemia major had been evaluated for their liver and cardiac T2*, 17 of them shows a mild LIC (liver iron concentration) and normal MIC (myocardial iron concentration), 49 patients show mild increase in both LIC and MIC, 9 show moderate LIC and mild MIC, 16 show moderate both LIC and MIC, 2 show severe LIC with mild MIC, only one shows severe LIC with moderate MIC and 6 of them show severe both LIC and MIC. There is a positive significant correlation between liver T2* and cardiac T2* (P values of 0.017), between liver T2* and LIC (P value of > 0.001), between liver T2* and MIC (P value of 0.031) and that between cardiac T2* and MIC (P value is >0.001). There is non- significant correlation between the age and frequency of blood transfusion with LIC and MIC (P value
