Myocardial 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
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 کاملT1 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...
