Comparing In vivo T2* and T2 Measurements in Tissues of Liver and Heart in thalassemia
Introduction: Cardiac complications secondary to iron overload are the leading cause of death in thalassemia major (TM). Cardiovascular magnetic resonance (CMR) can provide a noninvasive means of measuring the amount of tissue iron. With CMR, tissue iron is detected indirectly by the effect on relaxation times of hydrogen nuclei in the presence of ferritin and hemosiderin iron. The iron results...
متن کاملFree breathing myocardial T2 measurements
INTRODUCTION: Quantitative measurements of Magnetic Resonance tissue parameters is a valuable tool for tissue characterisation and functional imaging. For instance, myocardial T2 quantification is used to detect early rejection of heart transplant [1]. These T2 values are usually estimated by performing several black blood FSE sequences with different Echo Times (TE), thus requiring multiple br...
متن کاملCorrelation between Heart and Liver Iron Levels Measured by MRI T2* and Serum Ferritin in Patients with β-thalassemia Major
Background Transfusion-induced iron overload leads to many complications in patients with β-thalassemia major. This study aimed to compare the level of iron stored in the liver and heart measured by MRI T2 * with ferritin levels in these patients. Materials and Methods This study was done on 52 patients with β-thalassemia major aged 7 to 29 years. Serum ferritin level was checked and heart and ...
متن کاملBlack-blood T2* technique for myocardial iron measurement in thalassemia.
PURPOSE To compare the effectiveness and reproducibility of a new black-blood sequence vs. a conventional bright-blood gradient-echo T2* sequence for myocardial iron overload measurement in thalassemia. MATERIALS AND METHODS Twenty thalassemia patients were studied. Black-blood sequence images were acquired in diastole after a double inversion recovery (DIR) preparation pulse. Bright-blood se...
متن کاملFree-breathing myocardial T2 measurements at 1.5T
Introduction Myocardial T2 mapping is a valuable tool for tissue characterization and oedema visualization. For instance, it is used to detect early rejection of heart transplant [1]. T2 values are usually estimated by performing several black blood Fast Spin Echo (FSE) sequences with different Echo Times (TE), what requires multiple breath holds. Successive apneas could lead to misregistration...
