Myocardial T1 mapping with spectrally-selective inversion pulse to reduce the influence of fat
نویسندگان
چکیده
Background Changes in the longitudinal relaxation time (T1) of the myocardium are considered an important imaging-based biomarker to detect and quantify diffuse fibrosis. Several sequences have been suggested to measure myocardial T1 values [1]. However, T1 measurements are often influenced by the presence of intramyocardial or epicardial fat [2,3,4]. The aim of this study was to minimize the effect of fat in T1 mapping by the use of a water selective inversion pulse and to investigate the impact of this spectrally-selective inversion pulse on T1 measurements in the presence of field inhomogeneities.

Improved fat water separation with water selective inversion pulse for inversion recovery-based cardiac MRI sequence
Background Chemical shift based water-fat separation methods can be used to reconstruct simultaneous fat and water images, thereby improving the sensitivity of fat detection using a positive fat contrast. The presence of fatty infiltration is a hallmark pathological feature of arrhythmogenic right ventricular cardiomyopathy (ARVC). Furthermore, the presence of fatty infiltration in chronic myoc...

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...

Background :Inversion recovery (IR) pulse sequences can generate T1-weighted images with a different range of inversion time (TI) to suppress or null the signal intensity (SI) for a specified tissue. In this study, we aimed to investigate the effect of TI values on the concentration of the contrast agent, which leads to a minimum signal intensity, using an inversion recovery T1-weighted 3-dim...
