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 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 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 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 کاملT2-mapping and T1-mapping detect myocardial involvement inTako-Tsubo cardiomyopathy: a preliminary experience
Background T2and T1-mapping are novel CMR techniques allowing objective tissue characterization. These techniques have been shown to be superior to dark blood imaging in NSTEMI patients in detecting ischaemic area at risk and acute oedema. These methods have not been assessed in Tako-Tsubo cardiomyopathy (TC).The aim of the study was to assess myocardial involvement using T2and T1mapping in Tak...
