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 کاملT1 mapping in ischaemic heart disease.
A unique feature of cardiac magnetic resonance is its ability to characterize myocardium. Proton relaxation times, T1, T2, and T2* are a reflection of the composition of individual tissues, and change in the presence of disease. Research into T1 mapping has largely been focused in the study of cardiomyopathies, but T1 mapping also shows huge potential in the study of ischaemic heart disease. In...
متن کاملThe right ventricle in congenital heart disease - Cardiac T1 mapping for measurements of diffuse myocardial fibrosis
Background Measurements of myocardial extracellular volume (ECV) through cardiac magnetic resonance (CMR) based T1 mapping allow for non-invasive quantification of diffuse myocardial fibrosis. The evaluation of the right ventricle (RV), often mainly affected in congenital heart disease (CHD), is complicated by its typical morphologic characteristics a thin myocardium and a distinct trabeculatio...
متن کاملInsights from T1 mapping in heart failure
Methods Sixteen healthy subjects and 35 patients with heart failure awaiting guideline indicated CRT or primary prevention ICD (16 non ischemic cardiomyopathy (NICM), 19 ischemic cardiomyopathy (ICM)) were scanned on a 1.5T Magnetom Avanto (Siemens Healthcare, Erlangen) using a MOLLI (investigational WIP#448, 5:3:3 acquisition scheme, motion correction and automatically generated T1 map). In al...
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...
