چکیده
pyruvate spectrum acquired prior to imaging. Figure 1: (a) The C pyruvate peak image. (b) The water image showing the 3 syringe phantom. Syringe 1 contained tap water, syringe 2 contained hyperpolarized pyruvate, and syringe 3 contained 3.27M urea at thermal equilibrium and 5 mM gadodiamide and therefore has signal enhancement. (c) Carbon spectra from the pyruvate syringe and (d) carbon spectra from the urea syringe. The pyruvate peaks, which are almost an order of magnitude lower than the source in syringe 2, are observed to than the actual pyruvate signal are observed to alias into syringe 3 due to spatial undersampling. (e) Cropped color coded results with water (blue) and pyruvate (green) image. Simultaneous Proton and Hyperpolarized Carbon Imaging

High-Resolution Low-Field Molecular Magnetic Resonance Imaging of Hyperpolarized Liquids
We demonstrate the feasibility of microscale molecular imaging using hyperpolarized proton and carbon-13 MRI contrast media and low-field (47.5 mT) preclinical scale (38 mm i.d.) 2D magnetic resonance imaging (MRI). Hyperpolarized proton images with 94 × 94 μm(2) spatial resolution and hyperpolarized carbon-13 images with 250 × 250 μm(2) in-plane spatial resolution were recorded in 4-8 s (large...
متن کاملMulti-channel metabolic imaging, with SENSE reconstruction, of hyperpolarized [1-(13)C] pyruvate in a live rat at 3.0 tesla on a clinical MR scanner.
We report metabolic images of (13)C, following injection of a bolus of hyperpolarized [1-(13)C] pyruvate in a live rat. The data were acquired on a clinical scanner, using custom coils for volume transmission and array reception. Proton blocking of all carbon resonators enabled proton anatomic imaging with the system body coil, to allow for registration of anatomic and metabolic images, for whi...
متن کاملSignal-to-noise ratio comparison of encoding methods for hyperpolarized noble gas MRI.
Some non-Fourier encoding methods such as wavelet and direct encoding use spatially localized bases. The spatial localization feature of these methods enables optimized encoding for improved spatial and temporal resolution during dynamically adaptive MR imaging. These spatially localized bases, however, have inherently reduced image signal-to-noise ratio compared with Fourier or Hadamad encodin...
متن کاملCerebral Perfusion Imaging with a Hyperpolarized Freely Diffusible Contrast Agent
Introduction: Hyperpolarized contrast agents have a number of attractive features for application to perfusion imaging [1]. Indeed, these agents provide high signal strength with virtually no endogenous background signal and therefore make excellent tracers for monitoring blood flow. In comparison to arterial spin labeling (ASL), which produces signal modulations on the order of a few percent, ...
متن کاملSimultaneous PET/MRI with 13C magnetic resonance spectroscopic imaging (hyperPET): phantom-based evaluation of PET quantification
BACKGROUND Integrated PET/MRI with hyperpolarized (13)C magnetic resonance spectroscopic imaging ((13)C-MRSI) offers simultaneous, dual-modality metabolic imaging. A prerequisite for the use of simultaneous imaging is the absence of interference between the two modalities. This has been documented for a clinical whole-body system using simultaneous (1)H-MRI and PET but never for (13)C-MRSI and ...
