Journal ArticleDOI
Frontiers in musculoskeletal MRI: articular cartilage.
TL;DR: The techniques and uses of MRI in current clinical practice, primarily as a means to detect morphologic abnormalities, are reviewed, and ongoing development of techniques that can improve morphologic assessment including techniques to increase spatial and contrast resolution are discussed.
Journal ArticleDOI
Multi-vendor multi-site T1ρ and T2 quantification of knee cartilage.

TL;DR: This study showed promising results of multi-site, multi-vendor reproducibility of T1ρ and T2 values in knee cartilage and these quantitative measures may be applied in large-scale multi- Site repeatability and inter-site inter-Vendor reproduCibility trials with controlled sequence structure and scan parameters and centralized data processing.
Journal ArticleDOI
Proton T1ρ‐dispersion imaging of rodent brain at 1.9 T
Rahim R. Rizi,Sridhar R. Charagundla,Hee Kwon Song,Ravinder Reddy,Alan H. Stolpen,Mitchell D. Schnall,John S. Leigh +6 more
TL;DR: The signal‐to‐noise ratios of T1ρ‐weighted images are significantly better than comparable T2‐ Weighted images, allowing for improved visualization of tissue contrast, and the feasibility of proton T 1ρ‐dispersion imaging for detecting intravenous H217O on a live mouse brain is demonstrated.
Journal ArticleDOI
Fast MRI of RF heating via phase difference mapping.
TL;DR: Proper image processing as a phase difference map between the probing image and the baseline image resulted in an image which quantitatively described the temperature increase of the phantom in response to a particular “test” imaging experiment.
Journal ArticleDOI
Characterization of paramagnetic effects of molecular oxygen on blood oxygenation level-dependent-modulated hyperoxic contrast studies of the human brain.
TL;DR: Signals observed around the brain periphery and in the ventricles suggest the effect of image distortions from oxygen‐induced bulk B0 shifts, along with a possible contribution from decreased T 2* due to oxygen dissolved in the cerebrospinal fluid.
