Signs of fetal alcohol syndrome detected in womb
(Oregon Health& Science University) New images reveal the earliest impairments to nonhuman primate fetal brain development due to alcohol ingested by the mother, in a study led by scientists at Oregon Health& Science University involving rhesus macaques. Magnetic resonance imaging showed impairments to brain growth during the third trimester of pregnancy, even though the fetus was exposed to alcohol only during the first trimester.

Scientists show MRI predicts the efficacy of a stem cell therapy for brain injury
(Sanford Burnham Prebys Medical Discovery Institute) Scientists at Sanford Burnham Prebys Medical Discovery Institute and Loma Linda University Health have demonstrated the promise of applying magnetic resonance imaging (MRI) to predict the efficacy of using human neural stem cells to treat a brain injury -- a first-ever 'biomarker' for regenerative medicine that could help personalize stem cell treatments for neurological disorders and improve efficacy. The study was published in Cell Reports. (Source: EurekAlert! - Social and Behavioral Science)

MRI technique could reduce need for radiation in measuring tumor response to chemotherapy
(NIH/Eunice Kennedy Shriver National Institute of Child Health and Human Development) Whole body diffusion-weighted magnetic resonance imaging (DW MRI) may aid in the assessment of cancer treatment response in children and youth at much lower levels of radiation than current approaches, suggests a small study funded by the National Institutes of Health. The results appear in Radiology. (Source: EurekAlert! - Cancer)

$1 million to study treatment for first responders with PTSD
(McMaster University) The randomized control trial will focus on the effectiveness of a cognitive remediation strategy called Goal Management Training that is aimed at improving cognitive functioning among PSP with PTSD. Researchers will examine changes in everyday functional outcomes, like the ability to return to work, but also in brain structure and brain function using magnetic resonance imaging (MRI).

The genetic architecture of the human cerebral cortex
The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal...
