چکیده

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 the assessment of native T1 time with complete coverage of LV myocardium. The aim of this study was to investigate whether STONE sequence is useful for the assessment of regional variability of LV native T1 time in HCM patients.

Reproducibility 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...

Initial evidence of presence of papillary muscle diffuse fibrosis in patients with cardiomyopathy

Background The left ventricular (LV) papillary muscles (PM) are important structure for mitral valve complex. Previous studies by echocardiography demonstrated that PM function was impaired in patients with hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM). Native T1 mapping has emerged as a noninvasive magnetic resonance (MR) imaging method to assess LV diffuse myocardial fibr...

Free-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...

T1 mapping using a saturation recovery single-shot acquisition at 3 Tesla MRI in differentiation of normal myocardium from hypertrophic cardiomyopathy

Background Background Diffuse myocardial fibrosis is characteristic feature of hypertrophic cardiomyopathy (HCM). T1 mapping may enable non-invasive evaluation of diffuse myocardial fibrosis in HCM. There have been many studies that T1 mapping using a modified Look-Locker inversion recovery (MOLLI) sequence. However, there have been few studies using a SASHA for T1 mapping at 3 Tesla MRI. The p...

The necessity for full ventricular coverage with noncontrast T1 mapping in hypertrophic cardiomyopathy

Background Hypertrophic cardiomyopathy (HCM) is a genetic heart disease characterized by diverse phenotypic expression. T1 mapping is a novel CMR imaging sequence aimed at characterizing abnormal myocardial substrate. Current protocols obtain a mean T1 value derived from a single mid-LV short axis slice (single slice protocol) or three short-axis locations: apical, mid-LV and basal (three slice...
