MRI

A major step has been taken towards realizing a new form of MRI that could record biochemical reactions in the body as they happen. Duke University researchers report the discovery of a new class of molecular tags that enhance MRI signals by 10,000-fold and generate detectable signals that last over an hour. The tags are… Read more

The brains of children who suffer clinical depression as preschoolers develop abnormally, compared with the brains of preschoolers unaffected by the disorder, according to new research at Washington University School of Medicine in St. Louis. Their gray matter — tissue that connects brain cells and carries signals between those cells and is involved in seeing… Read more

One day people might inhale a magnetized gas, have an MRI on their lungs, and find out if they have asthma or another lung disease. For that to happen, scientists need to perfect the techniques used to create magnetized gas. Jaideep Singh, an assistant professor with the Michigan State University National Superconducting Cyclotron Laboratory, is… Read more

Every Tuesday and Thursday morning for a year and a half, Russell Poldrack started off his day by climbing into an MRI machine and scanning his brain for 10 minutes. The self-experimentation has made the psychologist’s brain the most studied in the world. Poldrack, who began the work at the University of Texas and has… Read more

Imaging patients soon after traumatic brain injury (TBI) occurs can lead to more accurate detection of cerebral microhemorrhages, or microbleeding on the brain, according to a study of military service members. Cerebral microhemorrhages occur as a direct result of TBI and can lead to severe secondary injuries such as brain swelling or stroke. The ability… Read more
