Arrhythmia insensitive rapid cardiac T1 mapping pulse sequence
PURPOSE To develop an arrhythmia-insensitive rapid (AIR) cardiac T1 mapping pulse sequence for quantification of diffuse fibrosis. METHODS An arrhythmia-insensitive cardiac T1 mapping pulse sequence was developed based on saturation recovery T1 weighting, which is inherently insensitive to heart rate and rhythm, and two single-shot balanced steady-state free precession image acquisitions with...
متن کاملRapid cardiac T1 mapping within two heartbeats
Introduction: T1-mapping offers a mean to quantitatively assess structural changes in the myocardium. Pre-contrast T1 mapping may assess areas at risk while post-contrast delayed-enhancement T1 mapping may assess myocardial infarction [1-3]. Multi-point T1 mapping approaches, such as Modified Look-Locker inversion recovery (MOLLI) [4], have been shown to detect changes in myocardial T1 in both ...
متن کاملA B1-insensitive High Resolution 2D T1 Mapping Pulse Sequence for Radial dGEMRIC of the Hip at 3T
Introduction Femoroacetabular impingement (FAI) [1] is a medical condition in which the abnormal contact between the acetabular rim and femoral neck causes labral and chondral damage that progress over time and can result in osteoarthritis (OA) of the hip. In FAI, detection of cartilage damage in its early stages is critical to the success of joint preserving surgeries aimed at correcting the b...
متن کاملComparison of ECV measurements during equilibrium between IR- and SR-based Cardiac T1Mapping
Background Cardiac T1 and extracellular volume fraction (ECV), derived from preand post-contrast cardiac and blood T1 measurements, are emerging imaging biomarkers of diffuse cardiac fibrosis. The most frequently used cardiac T1 mapping pulse sequence is MOLLI [1]. However, MOLLI is known to be sensitive to rapid heart rate and irregular rhythm, because it is based on inversion-recovery (IR) of...
متن کاملBlood T1 measurements using slice-interleaved T1 mapping (STONE) sequence
Background Slice interleaved T1 (STONE) mapping sequence was recently proposed to take advantage of increased recovery time of spins to improve accuracy and precision of native myocardial T1 values. In this sequence, a nonselective inversion pulse is followed by acquisition of the data for different slices. Therefore, blood pool may experience different recovery time at different slice location...
