چکیده
Fig. 3: Short-axis view a), image of the water resonance of the unsuppressed EPSI reference b), single average proton spectrum with the triglyceride (TG) resonance from the septal wall (marked voxel in b) c) and corresponding spectrum from 8 signal averages showing creatine (Cr) at 3.03 ppm d). Figure 2: Cardiac field map computed from an EPSI scan acquired without water suppression a). The sum over all resonances in the water suppressed EPSI scan shows only signal from the epicardial fat around the heart demonstrating sufficient water suppression.

Local-look navigator gated and cardiac triggered echo-planar spectroscopic imaging of the heart
Introduction Single-voxel proton magnetic resonance spectroscopy has been shown to be a promising tool for assessing creatine [1] and myocardial triglycerides in humans [2, 3, 4]. A focus of interest is the correlation between triglyceride content in the myocardium and cardiac dysfunction [5]. While spectral information from a single volume is sufficient when alterations with global effects on ...
متن کاملHigh resolution 3D spiral coronary vessel wall imaging with >99% respiratory efficiency using beat to beat respiratory motion correction: quantitative comparison with navigator gated 2D spiral and turbo spin echo imaging
Introduction: Dark blood coronary artery wall imaging has demonstrated the ability to detect vessel wall thickening in subjects with non-significant coronary heart disease [1]. For high resolution imaging, studies are generally performed with diaphragmatic navigator gating which has an inherently low respiratory efficiency (RE) and is further compromised by respiratory drift through the long ac...
متن کاملPrediction of long-term cardiac events by 123I-MIBG imaging after acute myocardial infarction and reperfusion therapy
Objective(s): In heart failure, the heart-to-mediastinum (H/M) ratio of the delayed image and washout rate (WR) are well-known as a powerful cardiac event predictors. H/M ratio quantifies the accumulation rate of MIBG in the myocardium and WR quantifies reduction of meta-iodobenzylguanidine (MIBG) accumulation in the heart from the early planar image to the delayed pla...
متن کاملFree-breathing renal MR angiography with steady-state free-precession (SSFP) and slab-selective spin inversion: initial results.
BACKGROUND The aim of our study was the investigation of a novel navigator-gated three-dimensional (3D) steady-state free-precession (SSFP) sequence for free-breathing renal magnetic resonance angiography (MRA) without contrast medium, and to examine the advantage of an additional inversion prepulse for improved contrast. METHODS Eight healthy volunteers (mean age 29 years) and eight patients...
متن کاملSelf-gated 4D whole-heart imaging
Background Suppressing cardiac and respiratory motion artifacts are major challenges in cardiac MRI. The conventional methods of ECG and diaphragm navigator gating require tedious setup, reduce the imaging efficiency significantly, are susceptible to drifts in heart rate or respiratory pattern, and can be unreliable at higher field strengths [1]. In this work, we propose a fully self-gated 4D i...
