  • Descrição: To compare the efficacy and reproducibility of black blood T2∗ to the conventional bright blood sequence in the assessment of myocardial iron concentration. We performed both conventional bright blood and black blood MRI T2∗ sequences in 50 thalassemia major patients, the results were statistically analyzed to assess the correlation of techniques, study reproducibility and interobserver agreement. Cardiac T2∗ values ranged from 2.39 to 47.9ms using bright blood sequence and 2.07 to 46.81 using the black blood sequence. There was positive significant correlation of both sequences in all patients. However the black blood technique was superior to bright blood technique as regards the study reproducibility (R2∗1.9± versus 2.4±14.7 p0.001) in addition to the better inter-observer agreement of black blood technique compared to the bright blood technique (3.2±1.2 versus 8.3±2.4 p0.001). Black blood T2∗ technique provides...
