متن کاملReproducibility of free-breathing multi-slice native myocardial T1 mapping using the slice-interleaved T1 (STONE) sequence
Background Quantitative myocardial T1 mapping is a promising technique for assessment of interstitial diffuse fibrosis. Recently, a novel T1 mapping sequence for free-breathing, multi-slice, myocardial T1 mapping using the sliceinterleaved T1 (STONE) has been developed [1], which was shown to provide superior accuracy compared to MOLLI [2]. However, in-vivo reproducibility and precision of this...
متن کاملDiffuse Myocardial Fibrosis detected by Multi-slice T1 Mapping using Slice Interleaved T1 (STONE) Sequence in Patients with Hypertrophic Cardiomyopathy
Background The presence of myocardial fibrosis is associated with worse clinical outcome in hypertrophic cardiomyopathy (HCM) patients. Due to the substantial variations in left ventricular (LV) wall thickness and fibrosis in HCM, volumetric coverage of entire LV myocardium is essential for the accurate assessment of myocardial fibrosis. Slice-interleaved T1 (STONE) mapping sequence allows for ...
متن کاملMyocardial T1 mapping at 3.0T using inversion recovery FLASH readout
Background Myocardial T1 mapping methods such as modified Look-Locker inversion-recovery (MOLLI) typically use balanced steady state free precession (bSSFP) readout, which is known to be particularly sensitive to off resonance and thus limits its utility at higher field strengths. Fast low angle shot (FLASH) imaging is known to be more robust against susceptibility artifacts than bSSFP. However...
متن کاملT1 mapping of myocardium using inversion recovery cine at 3.0T
Methods The sequence, IR-rttfl, performs realtime turboflash acquisition after an inversion pulse to capture the recovery of inverted magnetization. It is immune to T1 unrelated issues (e.g., field inhomogeneity). Diastolic images (about 12) are selected for T1 calculation using [4]. A trigger delay (about 300-400 ms) is applied before the inversion pulse so that initial magnetization recovery ...
