Small,Pamela N. Munster,Vivian Weinberg,Jan Henrik Ardenkjær-Larsen,Albert P. Chen,Ralph E. Hurd,Liv-Ingrid Odegardstuen,Fraser Robb,James Tropp,Jonathan Alan Murray +21 more
TL;DR: This first-in-man imaging study evaluated the safety and feasibility of hyperpolarized [1-13C]pyruvate as an agent for noninvasively characterizing alterations in tumor metabolism for patients with prostate cancer and showed elevated levels of lactate, alanine, and bicarbonate in regions of biopsy-proven cancer.
Journal ArticleDOI
Quantitative in vivo magnetic resonance imaging of multiple sclerosis at 7 Tesla with sensitivity to iron.
Kathryn E. Hammond,Meredith Metcalf,Lucas Carvajal,Darin T. Okuda,Radhika Srinivasan,Daniel B. Vigneron,Sarah J. Nelson,Daniel Pelletier +7 more
TL;DR: The purpose of this study was to quantify local field shifts in MS and to investigate their relation to disease duration and disability status.
Journal ArticleDOI
Development of methods and feasibility of using hyperpolarized carbon-13 imaging data for evaluating brain metabolism in patient studies.
Ilwoo Park,Peder E. Z. Larson,Jeremy W. Gordon,Lucas Carvajal,Hsin-Yu Chen,Robert Bok,Mark Van Criekinge,Marcus Ferrone,James B. Slater,Duan Xu,John Kurhanewicz,Daniel B. Vigneron,Susan M. Chang,Sarah J. Nelson +13 more
TL;DR: The purpose of this study was to develop and implement experimental strategies for using [1‐13C]pyruvate to probe in vivo metabolism for patients with brain tumors and other neurological diseases.
Journal ArticleDOI
High-resolution phased-array MRI of the human brain at 7 tesla: Initial experience in multiple sclerosis patients
Meredith Metcalf,Duan Xu,Darin T. Okuda,Lucas Carvajal,Radhika Srinivasan,Douglas A.C. Kelley,Pratik Mukherjee,Sarah J. Nelson,Daniel B. Vigneron,Daniel Pelletier +9 more
TL;DR: In this paper, the authors developed optimized high-resolution 7T MRI techniques using high sensitivity, specialized phasedarray coils, for improved gray matter (GM) and white matter differentiation, in an effort to improve visualization of multiple sclerosis (MS) lesions in vivo.
Journal ArticleDOI
In vivo bone and cartilage MRI using fully-balanced steady-state free-precession at 7 tesla.
Roland Krug,Julio Carballido-Gamio,Suchandrima Banerjee,Robert Stahl,Lucas Carvajal,Duan Xu,Daniel B. Vigneron,Douglas A.C. Kelley,Thomas M. Link,Sharmila Majumdar +9 more
TL;DR: It is shown that bSSFP and spin‐echo imaging is possible at higher field strengths within 3.2 W/kg specific absorption rate (SAR) constraints and there is SNR benefit and great potential for bone and cartilage imaging atHigher field strength.
