T1 Mapping in Characterizing Myocardial Disease
Cardiovascular magnetic resonance (CMR) is unique in its ability to noninvasively provide insights into cardiac morphology, myocardial architecture, blood flow, tissue perfusion, and function with high diagnostic accuracy and without needing ionizing radiation. In addition, CMR is also well suited to inform on the presence of subclinical disease and to unravel the complex pathophysiology of var...
متن کاملAdiabatic inversion pulses for myocardial T1 mapping.
PURPOSE To evaluate the error in T1 estimates using inversion-recovery-based T1 mapping due to imperfect inversion and to perform a systematic study of adiabatic inversion pulse designs in order to maximize inversion efficiency for values of transverse relaxation (T2) in the myocardium subject to a peak power constraint. METHODS The inversion factor for hyperbolic secant and tangent/hyperboli...
متن کاملT1 mapping: characterisation of myocardial interstitial space
UNLABELLED Myocardial fibrosis is always present in end-stage heart failure and is a major independent predictor of adverse cardiac outcome. Cardiac magnetic resonance (CMR) is an imaging method that permits a non-invasive assessment of the heart and has been established as the "gold standard" for the evaluation of cardiac anatomy and function, as well as for quantifying focal myocardial fibros...
متن کاملNative T1 Mapping for Myocardial Infarction
SEE PAGE 1019 C ardiac magnetic resonance (CMR) late gadolinium enhancement (LGE) (1) is the current clinical gold standard modality for evaluation of focal fibrosis and scar in patients with an ischemic or a nonischemic cardiomyopathy. LGE requires administration of an exogenous gadoliniumbased contrast agent, which accumulates in the scar region. LGE imaging is commonly performed using an inv...
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...
