Rapid T1 quantification based on 3D phase sensitive inversion recovery

Rapid T1 quantification based on 3D phase sensitive inversion recovery

BACKGROUND In Contrast Enhanced Magnetic Resonance Imaging fibrotic myocardium can be distinguished from healthy tissue using the difference in the longitudinal T1 relaxation after administration of Gadolinium, the so-called Late Gd Enhancement. The purpose of this work was to measure the myocardial absolute T1 post-Gd from a single breath-hold 3D Phase Sensitivity Inversion Recovery sequence (...

reviews Title : Rapid T 1 Quantification based on 3 D Phase Sensitive Inversion Recovery

Infarct quantification using 3D inversion recovery and 2D phase sensitive inversion recovery, validation in patients and ex vivo

BACKGROUND Cardiovascular-MR (CMR) is the gold standard for quantifying myocardial infarction using late gadolinium enhancement (LGE) technique. Both 2D- and 3D-LGE-sequences are used in clinical practise and in clinical and experimental studies for infarct quantification. Therefore the aim of this study was to investigate if image acquisitions with 2D- and 3D-LGE show the same infarct size in ...

Rapid T1 Determination with Optimized Inversion Recovery Sequence

Introduction: There is continuing interest in rapid quantitative measurements of spin-lattice relaxation time (T1). Conventionally, an inversionrecovery (IR) sequence is used to determine T1, with logarithmic spacing of inversion recovery times (ti), a long pre-delays (td), and with data fitted to a single-exponential equation. Spin-echo (SE) or fast-spin-echo (FSE) techniques may be applied fo...
