MR temperature imaging using PRF phase difference and a geometric model-based fat suppression method.

BACKGROUND Because protons in fat do not exhibit a temperature-dependent frequency shift, proton resonance frequency shift (PRFS)-based MR thermometry always suffers from disturbances due to the presence of fats or lipids. OBJECTIVE A new fat suppression method for PRFS-based MR thermometry is proposed to obtain accurate variation of phase angle. METHODS Similar to the approach of separatin...

Fat-suppression techniques for 3-T MR imaging of the musculoskeletal system.

Fat suppression is an important technique in musculoskeletal imaging to improve the visibility of bone-marrow lesions; evaluate fat in soft-tissue masses; optimize the contrast-to-noise ratio in magnetic resonance (MR) arthrography; better define lesions after administration of contrast material; and avoid chemical shift artifacts, primarily at 3-T MR imaging. High-field-strength (eg, 3-T) MR i...

Redundancy Encoding for Fast Dynamic MR Imaging using Structured Sparsity

For dynamic magnetic resonance imaging (MRI) applications, a critical requirement is to reduce image acquisition times while maintaining high resolutions and signal-to-noise ratios. In this paper, a fast MRI technique based on encoding of the k-space redundancy using data-driven dictionaries learned for sparse representation of signals is presented. The novelty of the technique lies in separati...

Hepatic glycogen signal detection in rats using Gaussian-weighted phase encoding C-13 MR spectroscopic imaging

Introduction: In mammals, carbohydrates are primarily stored in the form of hepatic glycogen. The content and synthesis/breakdown rates of hepatic glycogen in animal models can provide crucial information for diabetes research as well as a potential marker for the vitality of hepatocytes (e.g. after hepatocyte transplantation). In order to detect the 13C glycogen signal, Jucker et al. and Choi ...
