Joint 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...
متن کاملMyocardial T1 and T2 Mapping: Techniques and Clinical Applications
Cardiac magnetic resonance (CMR) imaging is widely used in various medical fields related to cardiovascular diseases. Rapid technological innovations in magnetic resonance imaging in recent times have resulted in the development of new techniques for CMR imaging. T1 and T2 image mapping sequences enable the direct quantification of T1, T2, and extracellular volume fraction (ECV) values of the m...
متن کاملJoint myocardial T1 and T2 mapping using a combination of saturation recovery and T2 -preparation.
PURPOSE To develop a heart-rate independent breath-held joint T1 -T2 mapping sequence for accurate simultaneous estimation of coregistered myocardial T1 and T2 maps. METHODS A novel preparation scheme combining both a saturation pulse and T2 -preparation in a single R-R interval is introduced. The time between these two pulses, as well as the duration of the T2 -preparation is varied in each ...
متن کاملT1 and T2 mapping reveal contribution of hemorrhage in myocardial remodeling following acute myocardial infarction
Background Hemorrhage is a frequent complication in acute myocardial infarction (AMI) and is speculated to be an independent predictor of adverse outcomes [1]. In addition to infarct zone remodeling, the distal remote myocardium may experience alterations vasodilator dysfunction, edema, and extracellular matrix (ECM) expansion [2-4]. The aim of our study was to understand the impact of hemorrha...
متن کاملSystolic T1 mapping for estimation of myocardial diffuse fibrosis
Background Parametric T1 mapping currently allows non-invasive estimation of diffuse left-ventricular fibrosis. Imaging for T1 mapping is usually acquired during the diastolic phase. However, in tachycardia and arrhythmia, diastasis is short and imaging challenging. Conversely, systolic T1 mapping might offer an advantage and further enable more accurate ROI delineation for T1 maps as the myoca...
