Molecular Imaging

 

In a recent editorial published in the November issue of The New England Journal of Medicine (NEJM), Werner Hacke, MD, PhD, DSc, discussed a new era of imaging selections for patients who are looking to benefit from a thrombectomy performed long after the onset of a stroke.

According to a new study published by the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine (AJRCCM), obstructive sleep apnea (OSA) may increase elderly individuals' risk of developing Alzheimer's disease.  

Using PET with the radiotracer 18F-florbetapir, researchers in Sweden have found that the topology of amyloid clusters can help tip off clinicians to the presence and progression of Alzheimer’s disease in patients who don’t yet present symptoms.

Radiology and orthopedics researchers at Stanford have shown the prowess of nuclear imaging for identifying the specific source(s) of pain and reduced mobility in patients with chronic sciatica, a common low-back condition notorious for evading such pinpointing.

The effects of space travel on the human anatomy are extensive to say the least, taking into account the harsh impact zero gravity and the rapid ascension into space have on the bodies of astronauts. Yet, the amount of information detailing the effects spaceflight has on the configuration of astronauts' brains is limited, claimed in a recent study published by The New England Journal of Medicine and funded by the National Aeronautics and Space Administration (NASA).

Teenage rebellion might be caused by abnormal brain development, study suggests

Researchers in the United Kingdom found a link between conduct disorder in adolescents and thickness of the outer layer of the brain, breaking down misconceptions that severe antisocial behavior and aggression is simply just a form of teenage rebellion. 

PET pinpoints tau tangles as cause of Alzheimer's effects

PET amyloid imaging does a fine job finding susceptibility to Alzheimer’s disease long before symptoms set in, but PET tau imaging is better at showing what’s going on once neuronal injury becomes functionally evident. 

Non-imaging MR application helps head off sepsis in children

An MR-based system for identifying pediatric cases of Candida infection has been shown capable of using low-volume blood specimens to efficiently diagnose or rule out candidemia, the deadliest form of sepsis-causing bloodstream infection.

Tau imaging: A better way to track Alzheimer’s progression?

A newly developed PET tracer has shown that tau protein clumps within the brain are better indicators of cognitive impairment related to Alzheimer’s disease than beta amyloid proteins, the current standard for evaluating the disease’s progress, according to results of a new study recently published in the journal Science Translational Medicine.

Handheld tool images tumor cells during neurosurgery

Researchers from the Barrow Neurological Institute at St. Joseph’s Hospital and Medical Center in Phoenix, Ariz., have created and tested a pen-sized imaging instrument to aid neurosurgeons in the visualization of individual tumor cells during ongoing brain operations, according to results of a study published in the April issue of Neurosurgical Focus.

Heads up: Helmet-sized scanner could be the future of PET imaging

Researchers are inching closer to the development of a wearable, helmet-like PET scanner capable of substantially increasing sensitivity and reducing patient exposure to radiation, according to results of a simulation study recently published online in the journal Physics in Medicine and Biology.

Neuroimaging helps distinguish abnormalities in the brains of NFL players

Perfusion neuroimaging using SPECT can detect abnormalities in the brains of retired and current National Football League players, distinguishing them from healthy control subjects, according to results of a new study published online in the Journal of Alzheimer's Disease.

A single season spent playing contact sports is all it takes for measurable changes to occur inside young athletes’ brains, according to results of a study recently published in the Journal of Neurotrauma.

Might epileptic memory disruptions respond to device-based intervention?

Working with data from both rats and humans, NYU Langone researchers have confirmed that certain abnormal discharges are likely behind the lag in the time it takes an epileptic brain to process memory signals traveling from the hippocampus to the cortex. 

Neuroimaging biomarker tracks autism treatment effectiveness in boys

A new method using neuroimaging to track brain function in boys affected by autism could provide doctors with a biomarker for how patients are responding to behavioral or drug treatments, according to results of a study published online in JAMA Psychiatry.
