Human cardiac 31P magnetic resonance spectroscopy at 7 tesla
PURPOSE Phosphorus magnetic resonance spectroscopy ((31)P-MRS) affords unique insight into cardiac energetics but has a low intrinsic signal-to-noise ratio (SNR) in humans. Theory predicts an increased (31)P-MRS SNR at 7T, offering exciting possibilities to better investigate cardiac metabolism. We therefore compare the performance of human cardiac (31)P-MRS at 7T to 3T, and measure T1s for (31...
متن کاملHuman Cardiac 31P-MR Spectroscopy at 3 Tesla Cannot Detect Failing Myocardial Energy Homeostasis during Exercise
Phosphorus-31 magnetic resonance spectroscopy (31P-MRS) is a unique non-invasive imaging modality for probing in vivo high-energy phosphate metabolism in the human heart. We investigated whether current 31P-MRS methodology would allow for clinical applications to detect exercise-induced changes in (patho-)physiological myocardial energy metabolism. Hereto, measurement variability and repeatabil...
متن کاملA 1H-31P Array Coil for Human Brain Spectroscopy at 3 T
Previously, a modular approach has been suggested for designing large arrays [1]. It is based on a stacked combination of loop coils and microstrip transmission-line (MTL) elements, which are intrinsically orthogonal. In this work, this concept was adopted to build a helmet-shaped, dual-tuned array coil for human brain P spectroscopy and H decoupling and imaging at 3 T. The H channel is based o...
متن کاملQuantification of Fatty Acid Compositions Using MR-imaging and Spectroscopy at 3 T
Introduction Multi-echo imaging has previously been used for fat/water separation and fat quantification [1,2]. The same technique may potentially also be able to differentiate different fat types depending on the amount of unsaturated fatty acids. The fatty acid composition of adipose tissue is not only dependent on the diet, but may also be interesting in e.g. chronic inflammations [3]. Also,...
متن کامل31P magnetization transfer magnetic resonance spectroscopy: Assessing the activation induced change in cerebral ATP metabolic rates at 3 T
PURPOSE In vivo 31 P magnetic resonance spectroscopy (MRS) magnetization transfer (MT) provides a direct measure of neuronal activity at the metabolic level. This work aims to use functional 31 P MRS-MT to investigate the change in cerebral adenosine triphosphate (ATP) metabolic rates in healthy adults upon repeated visual stimuli. METHODS A magnetization saturation transfer sequence with nar...
