Characterization of cardiac masses with T1 mapping
Cardiology, Hofstra North Shore-LIJ School of Medicine, Manhasset, NY, USA Full list of author information is available at the end of the article Figure 1 A1. A DIR TSE image demonstrates fat in the atrioventricular groove as well as a non-fat-based mass at the mitral annulus. A2. The corresponding T1 map shows a mass with a relatively low T1 value (417 ms) consistent with mitral annular calcif...
متن کاملRapid cardiac T1 mapping within two heartbeats
Introduction: T1-mapping offers a mean to quantitatively assess structural changes in the myocardium. Pre-contrast T1 mapping may assess areas at risk while post-contrast delayed-enhancement T1 mapping may assess myocardial infarction [1-3]. Multi-point T1 mapping approaches, such as Modified Look-Locker inversion recovery (MOLLI) [4], have been shown to detect changes in myocardial T1 in both ...
متن کاملImproved myocardial T1 mapping for patients with implanted cardiac devices
Background Myocardial T1 mapping holds promise for non-invasive evaluation of diffuse fibrosis. Nevertheless, the widely used cardiac T1 mapping techniques, including MOLLI and SASHA, are generally not applicable to patients with implanted cardiac devices, such as implantable cardioverter defibrillators (ICDs) and pacemakers, due to large off-resonance induced by the device and the associated b...
متن کاملTrue T1 mapping with SMART1Map (saturation method using adaptive recovery times for cardiac T1 mapping): a comparison with MOLLI
Background SMART1Map is a new single-point technique for cardiac T1 mapping [1]. Unlike Look-Locker approaches, such as MOLLI, which yield an “apparent” T1 (T1*), SMART1Map directly measures true T1. Because T1* is a function of imaging parameters, it is always shorter than T1, and correction methods are required to obtain the true T1. This work compared the accuracy of SMART1Map with MOLLI in ...
متن کاملEstimation of cardiac amyloid infiltration with myocardial T1 mapping correlates with severity of cardiac involvement
Background Post-contrast myocardial T1-mapping with cardiac magnetic resonance (CMR) has shown usefulness in the diagnosis of cardiac amyloid. A lower value indicates increase in extracellular volume and thereby amyloid deposition. The aim of this study is to assess the association between the amount of amyloid deposition as estimated by the degree of post-contrast myocardial T1 reduction and t...
