Black-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 کاملRobust myocardial T2 and T2* mapping at 3T
PURPOSE Intramyocardial hemorrhage and area at risk are both prognostic markers in acute myocardial infarction (AMI). Myocardial T2 and T2 * mapping have been used to detect such tissue changes at 1.5T but these techniques are challenging at 3.0T due to additional susceptibility variation. We studied T2 and T2 * myocardial mapping techniques at 3.0T on a system employing B1 shimming and compare...
متن کاملThe Accuracy of Myocardial T2-Mapping Techniques
Objective: 1. To evaluate different pulse sequence options available for T2 Mapping of human myocardium vis-à-vis accuracy of T2 measurements in phantoms. 2. To propose a practical approach to T2 evaluation that can be used in clinical setting to distinguish tissues with T2 differences 3. To get a range of values for human myocardial T2 values using the most accurate and practical approach. 4. ...
متن کاملJoint myocardial T1 and T2 mapping
Background Recent studies suggest that quantitative myocardial T1 mapping allows assessment of focal and diffuse fibrosis in the myocardium [1]. Quantitative T2 mapping has also been proposed to overcome challenges associated with T2 weighted imaging [2]. These maps are traditionally acquired with different sequences, necessitating image registration to evaluate them jointly. A sequence that ca...

Ziel: Ziel der vorliegenden Studie war es, zu untersuchen mit welcher diagnostischen Genauigkeit das T2-Mapping die Visualisierung eines Myokardödems beim akuten Myokardinfarkt (AMI) erlaubt und diese diagnostische Genauigkeit mit der des gegenwärtigen Standards für die myokardiale Ödembildgebung (T2-gewichtete, dark-blood präparierte TSE-Sequenz) zu vergleichen. Material und Methoden: 29 Patie...
