Breath-hold spiral tissue phase velocity mapping (TPVM) with non-Cartesian SENSE
high temporal resolution TPVM data over the entire NIHR CBRU, Imperial College, London, UK Figure 1 a) Global velocities from 9 short axis slices in one volunteer (each curve represents velocity averaged over a slice). In longitudinal and radial directions one systolic (SL/SR), one early diastolic (DL/DR) and one atrial systolic (ASL/ASR) peak is seen. Longitudinal peaks reduce from base to ape...
متن کاملRetrogated spiral 3-directional myocardial phase velocity mapping in a single breath-hold
Background Myocardial phase velocity mapping studies have generally been acquired using Cartesian k-space coverage and respiratory gating [1,2]. Acquisition durations for high temporal resolution studies are therefore long and unpredictable and the use of navigators and prospective cardiac gating results in ‘dead-times’ in the cardiac cycle where imaging cannot be performed. We have developed a...
متن کاملWhole-heart T1-mapping with single breath-hold
Background T1-mapping, directly measuring the underlying longitudinal relaxation times (T1), and extracellular volume (ECV) quantification, are emerging techniques for myocardial fibrosis quantification. Recent studies have reported significant T1 differences in fibrotic and normal tissue, but whole-heart T1-mapping is rarely performed in clinical practice, due to the associated time-consuming ...

R egeneration, the process by which an animal restores lost cells or body parts, occurs throughout the animal kingdom, including vertebrates, planarians and cnidarians such as hydra (Tanaka & Reddien, 2011). However, the ability to regenerate varies between species, and within a species it can be different for different body parts. Salamanders, such as axolotls and newts, possess the most impre...
