Optimal real-time estimation in diffusion tensor imaging
03 February 2012
Pablo Casaseca-de-la-Higuera, Antonio Tristán-Vega, Santiago Aja-Fernández, Carlos Alberola-López, Carl-Fredrik Westin, Raúl San José Estépar
Abstract: Diffusion tensor imaging (DTI) constitutes the most used paradigm among the diffusion-weighted magnetic resonance imaging (DW-MRI) techniques due to its simplicity and application potential....

Signal evolution in the local magnetic field of a capillary — analogy to the damped driven harmonic oscillator
03 February 2012
Christian H. Ziener, Thomas Kampf, Gerd Melkus, Peter M. Jakob, Heinz-Peter Schlemmer, Wolfgang R. Bauer
Abstract: The temporal behavior of the magnetization decay caused by the local inhomogeneous magnetic field of a capillary is analyzed. Respecting the diffusion of the spins surrounding the capillary ...

Multichannel transceiver dual-tuned RF coil for proton/sodium MR imaging of knee cartilage at 3 T
01 February 2012
Jung-Hwan Kim, Chan Hong Moon, Bum-Woo Park, Alessandro Furlan, Tiejun Zhao, Kyongtae T. Bae
Abstract: Sodium magnetic resonance (MR) imaging is a promising technique for detecting changes of proteoglycan (PG) content in cartilage associated with knee osteoarthritis. Despite its potential cli...

Globally optimized fiber tracking and hierarchical clustering — a unified framework
30 January 2012
Xi Wu, Mingyuan Xie, Jiliu Zhou, Adam W. Anderson, John C. Gore, Zhaohua Ding
Abstract: Structural connectivity between cortical regions of the human brain can be characterized noninvasively with diffusion tensor imaging (DTI)-based fiber tractography. In this paper, a novel fi...
