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

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 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 (...

Free-breathing Delayed-enhancement 3D MRI With and Without Phase-sensitive Inversion-Recovery

Introduction Free-breathing 3D delayed-enhancement MRI (DE-MRI) has been developed to improve the spatial resolution of the DE-MRI, to generate multi-planar reconstruction, and to eliminate the laborious breath-holds. However, the gadolinium washout during the 4-11-min (mean, about 7 min) scan of the free-breathing 3D DE-MRI may reduce the image contrast because of gadolinium washout from the m...

Quantification of myocardial viability in diffuse and contiguous infarction using 3D inversion recovery MRI: Validation against microscopy

Background Sheifer et al indicated that undetected infarction account for at least 20% of all infarctions and carry a prognosis as poor as detected ones [1]. Large myocardial infarction has been measured using both 3D and 2D delayed enhancement MRI, which was compared with histochemical staining [2]. The purpose of this MRI study was to 1) measure diffuse and large infarction size using delayed...
