Free-breathing multi-slice myocardial T2 mapping using slice-selective T2 magnetization preparation
Background Quantitative myocardial T2 mapping allows non-invasive assessment of myocardial inflammation/edema [1]. Current implementations commonly use a T2-prepared (T2prep) SSFP sequence to acquire different T2 weighted images at different echo times to generate the T2 maps [2,3]. However, all current techniques are designed for single slice acquisition with long rest cycles (3-6 sec) after e...
متن کاملReproducibility 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...
متن کاملFree-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...
متن کاملFree-breathing myocardial T1 mapping using magnetization-prepared slice interleaved spoiled gradient echo imaging
Background Quantitative myocardial T1 mapping and extracellular volume fraction (ECV) show promise for non-invasive assessment of cardiomyopathies. Most available T1 mapping sequences use a single slice breath-hold acquisition with balanced steady state free precession (b-SSFP) readout [1]. However, b-SSFP readout is sensitive to B0 field inhomogeneity and is potentially T2 dependent [1]. In th...
متن کاملEvaluation of a free-breathing myocardial T1 mapping using magnetization-prepared slice interleaved spoiled gradient echo imaging in patient
Background Quantitative myocardial T1 mapping shows promise for assessment of various cardiomyopathies. Most available sequences are generally acquired within a breath-hold using a balanced SSFP (bSSFP) imaging readout. However, the signal obtained from a bSSFP imaging readout is T2 dependent, sensitive to magnetization transfer and has increased susceptibility to the B0 field inhomogeneity lea...
