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 کامل3D saturation recovery imaging for free breathing myocardial T1 mapping
Background Longitudinal magnetization relaxation time (T1) mapping can overcome limitations of late gadolinium enhancement for the detection of diffuse fibrosis in the myocardium. Several T1 mapping methods have been proposed in recent years; however most of them are limited to 2D breath-hold acquisitions with associated limitations in signal-to-noise ratio (SNR) and spatial resolution. A MOdif...
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 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 کاملFree-breathing multislice native myocardial T1 mapping using the slice-interleaved T1 (STONE) sequence.
PURPOSE To develop a novel pulse sequence for free-breathing, multislice, native myocardial T1 mapping. METHODS The slice-interleaved T1 (STONE) sequence consists of multiple sets of single-shot images of different slices, acquired after a single nonselective inversion pulse. Each slice is only selectively excited once after each inversion pulse to allow sampling of the unperturbed longitudin...
