Journal ArticleDOI
Imaging of glutamate neurotransmitter alterations in Alzheimer's disease.
Mohammad Haris,Kavindra Nath,Kejia Cai,Anup Singh,Rachelle Crescenzi,Feliks Kogan,Gaurav Verma,Sanjana Reddy,Hari Hariharan,Elias R. Melhem,Ravinder Reddy +10 more
TL;DR: A positive correlation was observed between GluCEST contrast and 1H MRS‐measured Glu/total creatine ratio and this method potentially provides a novel noninvasive biomarker for the diagnosis of the disease in preclinical stages and enables the development of disease‐modifying therapies for AD.
Journal ArticleDOI
Human Knee: In Vivo T1ρ-weighted MR Imaging at 1.5 T—Preliminary Experience
Umamaheswar Duvvuri,Sridhar R. Charagundla,Sagar B. Kudchodkar,Jonathan H. Kaufman,J. Bruce Kneeland,Rahim R. Rizi,John S. Leigh,Ravinder Reddy +7 more
TL;DR: A fast spin-echo sequence weighted with a time constant that defines the magnetic relaxation of spins under the influence of a radio-frequency field (T1(rho)) was used in six subjects to measure magnetic resonance (MR) relaxation times in the knee joint with a 1.5-T MR imager.
Journal ArticleDOI
The Impact of Gabapentin Administration on Brain GABA and Glutamate Concentrations: A 7T 1H-MRS Study
Kejia Cai,Ravi Prakash Reddy Nanga,Lisa Lamprou,Claudia Schinstine,Mark A. Elliott,Hari Hariharan,Ravinder Reddy,C. Neill Epperson +7 more
TL;DR: In this paper, a gabapentin (900mg) challenge was conducted in healthy human subjects to test the ability of single voxel localized proton magnetic resonance spectroscopy (1H-MRS) to reliably measure GABA and glutamate in the visual cortex at the ultra-high magnetic field of 7 Tesla.
Journal ArticleDOI
In Vivo Proton MR Three-dimensional T1ρ Mapping of Human Articular Cartilage: Initial Experience
TL;DR: The feasibility of computing three-dimensional relaxation maps of spin-lattice relaxation time in the rotating frame (T1rho) from in vivo magnetic resonance (MR) images of the human patellofemoral joint was demonstrated.
Journal ArticleDOI
Sodium visibility and quantitation in intact bovine articular cartilage using high field (23)Na MRI and MRS.
TL;DR: Sodium distribution maps of the cartilage are created, showing for the first time, spatial variations of sodium concentration in intact cartilage, and sodium was found to be 100% NMR visible in cartilage plugs.
