Neuroradiology

Neuroradiology specializes in the use of x-rays and scanning devices for the diagnosis and treatment of diseases of the brain and nervous system. Primary imaging modalities used in neuroradiology include computed tomography (CT) and magnetic resonance imaging (MRI). Oakstone Publishing, LLC is accredited by the Accreditation Council for Continuing Medical Education to provide continuing medical education for physicians, including its popular neuroradiology DVD program.

A health-insurance company’s “price transparency program” succeeded in driving insured patients to less-expensive MRI facilities and away from hospital-based facilities, according to an article in the current edition of Health Affairs.

The insurer was WellPoint. One of its subsidiaries commissioned the study, and another conducted it. The study looked at more than 100,000 members of WellPoint health plans from 2010 through 2012. … read more »

Stress in early childhood is associated with subtle differences in brain structure that can have significant negative effects on behavior, health, and other aspects of later life, according to a new study led by University of Wisconsin-Madison researchers.

The differences in the size of the hippocampus and amygdala were so small that the researchers had to hand-trace around the structures in … read more »

The discovery by University of Wisconsin researchers of genes that are necessary for surviving high levels of radiation has potentially big implications for imaging and radiation therapy.

The researchers developed a highly radiation–resistant strain of Escherichia coli by exposing cultures of the bacterium to extreme doses of radiation. “We blasted the cultures until 99 percent of the bacteria were dead,” said Michael M. … read more »

A new type of nanoparticle actively seeks out cancer cells, then automatically assembles itself into clumps large enough to clearly show up on MRI scans.

Researchers at Imperial College London created the nanoparticle to increase both the sensitivity and specificity of MRI in detecting small, early-stage tumors. Nicholas J. Long, PhD, the Sir Edward Frankland BP Chair of Inorganic Chemistry, explained … read more »

In emergency department treatment of stroke patients, every second counts. Practice guidelines recommend giving ischemic stroke patients a clot-busting tPA injection within 60 minutes. So which takes longer: getting patients in the door and ready for imaging (door-to-imaging time, or DIT), or getting patients imaged and, if they’re suffering from ischemic stroke, giving them tPA (imaging-to-needle time, or ITN)?

Surprisingly, it’s … read more »

Two new studies look at imaging-related lessons from the April 2013 terrorist bombing attack during the Boston Marathon—one of interest to post-traumatic stress disorder researchers, and the other of concern primarily to radiologists and the institutions where they practice.

The bombing presented an unanticipated opportunity for a group of researchers who had performed functional MRI brain scans on Boston-area teenagers for … read more »

Mayo Clinic and 10 other institutions from around the United States are leading an effort to institute a national protocol to limit radiation dosage when imaging children.

Representatives of the institutions published an invited commentary titled “An Appeal for Safe and Appropriate Imaging of Children” online last week in Journal of Patient Safety. Lead author Stephen J. Swensen, MD, a radiologist at … read more »

MRI, by detecting changes in a specific area of the brain, may be able to predict which children will later develop epilepsy after suffering fever-related seizures, according to new research.

The finding, published last month in The Journal of Neuroscience, is based on studies of rats, so considerable  work remains before the technique could possibly reach clinical use. But the marker seems promising … read more »

Even loss of consciousness from a blow to the head is not by itself reason enough to give a child a cranial CT scan, according to research published online Monday in JAMA Pediatrics.

Nathan Kuppermann, MD, senior author of the article and principal investigator for the Pediatric Emergency Care Applied Research Network (PECARN), from which the article’s data and analysis were derived, summarized the research … read more »
