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 slice-interleaved myocardial T2 mapping sequences
Background Myocardial T2 mapping sequence allows quantitative assessment of myocardial edema and inflammation. Commonly, a series of T2 weighted images with steadystate free-precession (SSFP) are acquired after T2 magnetization preparation (T2Prep) with different echo times. Conventionally, a single slice per breath-hold is acquired to image one single slice. Because inflammation/edema is often...
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 کاملFree breathing myocardial T2 measurements
INTRODUCTION: Quantitative measurements of Magnetic Resonance tissue parameters is a valuable tool for tissue characterisation and functional imaging. For instance, myocardial T2 quantification is used to detect early rejection of heart transplant [1]. These T2 values are usually estimated by performing several black blood FSE sequences with different Echo Times (TE), thus requiring multiple br...
متن کاملSimultaneous Quantitation of T1 and T2 Using a Novel 2D Magnetization-Prepared Multi-Slice Pulse Sequence
Introduction In recent years numerous approaches for the efficient, accurate and simultaneous quantitation of T1, T2, and M0 have been proposed – Ref 1 and 2 among them. Indeed, growing interest in generating synthetic MR images [2] and in “quantitative” tissue characterization continues to drive technical developments in MR relaxometry. Here we propose a novel 2D multi-slice pulse sequence tha...
