Saturation recovery allows T1 mapping in the human heart at 7T with a commercial MRI scanner

چکیده
Background Myocardial T1 mapping at 1.5T and 3T distinguishes powerfully between normal and diseased tissue with focal and diffuse pathology. We recently reported the first human myocardial T1s at 7T using the ShMOLLI +IE inversion recovery sequence. Yet even using a unique 7T scanner with 16kW RF output, perfect magnetization inversion was impossible. We now introduce a saturation recovery method to enable myocardial T1 mapping with standard commercial 7T MRI scanners.

3D myocardial T 1 mapping using saturation recovery
PURPOSE To propose a 3D quantitative high-resolution T1 mapping technique, called 3D SASHA (saturation-recovery single-shot acquisition), which combines a saturation recovery pulse with 1D-navigator-based-respiratory motion compensation to acquire the whole volume of the heart in free breathing. The sequence was tested and validated both in a T1 phantom and in healthy subjects. MATERIALS AND ...

OBJECT To develop and evaluate a 2D modified Look-Locker (MOLLI) for high-resolution T1 mapping in mice using a 3T MRI scanner. MATERIALS AND METHODS To allow high-resolution T1 mapping in mice at high heart rates a multi-shot ECG-triggered 2D MOLLI sequence was developed. In the proposed T1 mapping sequence the optimal number of sampling points and pause cardiac cycles following an initial a...
متن کاملT1 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...
متن کاملTheory-based single-point T1 mapping for quantitative analysis of first-pass cardiac perfusion MRI: a validation study
Introduction: Quantitative analysis of first-pass contrast-enhanced cardiac perfusion MRI requires a conversion of the T1-weighted signal-time curve to contrast agent (Gd-DTPA) concentration-time curve. For this purpose, a theory-based single-point T1 measurement method has been proposed and validated in phantoms at 1.5T [1-2]. The specific choice of the k-space ordering of the TurboFLASH reado...

OBJECTIVES To demonstrate the image quality that can be obtained for multiple contrasts using ultra-high resolution MRI (highest nominal resolution: 350 μm isotropic) at 7T using appropriate motion-correction. MATERIALS AND METHODS An MRI-based fat-excitation motion navigator (which requires no additional hardware) was incorporated into T1-weighted (MP2RAGE, 350 μm nominal isotropic resolutio...
