Molecular Imaging

 

According to a recent National Institutes of Health (NIH) press release, new research suggests that genetic variations in the lungs can differentiate between individuals who have stably low lung function early in life (that steadily declines with age) versus those who are at risk for chronic obstructive pulmonary disease (COPD) due to smoking.  

Researchers from the Chinese University of Hong Kong and Ann & Robert H. Lurie Children's Hospital of Chicago have combined international expertise and two types of technology to predict how well a deaf child can learn language after receiving cochlear implant surgery. 

A team of researchers has proven a new radiotracer, 2-18F-fluorodeoxysorbitol (18F-FDS), more adept at tracking bacterial infection in lungs than current imaging methods, while also distinguishing bacterial infection from inflammation.

Head trauma and sports—most notably football but also hockey, soccer and boxing—have been the focus of plenty of media coverage. Recent studies have shown an overwhelming majority of deceased football player’s brains contained evidence of chronic traumatic encephalopathy, or CTE.

PET is already considered the most sensitive non-surgical techniques for studying physiology, metabolism and molecular pathways, but experts believe recent developments may drastically increase its capabilities.

PET scans show patients with PTSD have imbalance in brain's signalling systems

Researchers set out to study patients with post-traumatic stress disorder (PTSD) using PET scans. They found that a greater imbalance between two neurochemical systems in the brain—serotonin and substance P—meant individuals were more likely to experience PTSD symptoms.

Study: Brains of NFL players contain increased localized injuries, changes in white matter

For years now, research has emerged to show the effects of playing football—including repetitive concussive and sub-concussive hits—may lead to major brain damage. Now, a new study further explores the topic and affirms that players in the National Football League (NFL) could be at a higher risk for brain injuries.

Imaging technique gets docs closer to treating Alzheimer’s, Parkinson’s

Researchers from the University of Cambridge in the U.K. have developed a new imaging technique that could help create treatments for Alzheimer’s and Parkinson’s diseases.

ASNC, IAC, SNMMI in sync to mandate optimized radiation doses in nuclear cardiology

Organizations are working in sync to put a focus on mandating optimized radiation doses in nuclear cardiology studies performed across the nation and beyond. 

Diffusion MRI used to measure brain's local connectome

Putting assumptions to rest in neuroscience, a group of researchers used an MRI approach and found that the connectivity patterns in your brain are unique to you.

MRI reveal differences in brain regions of children with Tourette syndrome

The largest study of brain structure ever reported in children with Tourette syndrome (TS) found that children with the neuropsychiatric disorder appear to have a lower white matter volume in their brain compared to those without it.

‘Placebo effect’ region in brain mapped by fMRI

Researchers at Northwestern University and the Rehabilitation Institute of Chicago (RIC) say functional MRI (fMRI) helped derive a brain-based marker predicting the “placebo effect,” potentially leading to treatment plans accounting for patients with high positive responses to placebos.

Medical imaging associated with development of Alzheimer's

Ionizing radiation from medical scans may be implicated in Alzheimer’s disease, according to a Danish study published in Oncotarget.

University of Michigan research reveals new theories about PTSD

New research from the University of Michigan suggests that post-traumatic stress disorder (PTSD) stems from physical processes in the brain and not from psychological weakness, as many have believed.

Can you drink too much water? fMRI research says you can

Many of us struggle to drink the recommended eight glasses of water per day, but a new study suggests that we're not supposed to.
