Journal ArticleDOI
MRI characterization of diffusion coefficients in a rat spinal cord injury model
John C. Ford,David B. Hackney,David C. Alsop,Hernan Jara,Peter M. Joseph,Christopher M. Hand,Perry Black +6 more
TL;DR: ADC measurement may complement routine imaging for evaluation of spinal cord injury and decrease in ADCs measured along the longitudinal axis of the injured cord and increases measured transverse to the cord.
Journal ArticleDOI
High‐resolution variable flip angle 3D MR imaging of trabecular microstructure in vivo
TL;DR: In this paper, variable flip-angle spin-echo pulse sequences were designed for imaging at voxel sizes of 2-5 x 10-3 mm3 corresponding to pixel areas of less than 100 x 100 microns2 and section thicknesses on the order of 300-400 microns on a conventional 1.5 T MR imaging system equipped with 1 G/cm imaging field gradients.
Journal ArticleDOI

Singh,Shehzad Basaria +27 more
TL;DR: Changes in fat-free mass in response to graded testosterone doses did not differ in men in whom DHT was suppressed by dutasteride from those treated with placebo, indicating that conversion of testosterone to DHT is not essential for mediating its anabolic effects on muscle.
Journal ArticleDOI
Neurocognitive and Academic Outcomes at Age 10 Years of Extremely Preterm Newborns
Robert M. Joseph,Thomas M. O'Shea,Elizabeth N. Allred,Elizabeth N. Allred,Timothy Heeren,Deborah Hirtz,Hernan Jara,Alan Leviton,Alan Leviton,Karl C.K. Kuban +9 more
TL;DR: More than half of the extremely preterm cohort exhibited moderate or severe neurocognitive deficits at age 10 years, with the most extensive impairments found among those born at the lowest gestational age.

Synthetic images for a magnetic resonance imaging scanner using linear combination of source images to generate contrast and spatial navigation
TL;DR: In this article, three image-postprocessing phases for the purposes of generating high quality quantitative MR images (proton density (PD), T1, and T2) as well as high quality virtual MR images with continuously adjustable computer-synthesized contrast weightings, from source images acquired directly with an MRI scanner.
