Molecular Imaging

 

Imaging professionals are well aware of the effects of concussion, from long-term damage to professional football players to kids playing water polo. Recent research in JAMA Pediatrics examined how changes in epigenetic molecules known as microRNAs (miRNAs) can be monitored via children’s saliva to detect prolonged concussion symptoms.

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.

Mallinckrodt to sell nuclear medicine business to IBA Molecular for $690 million

Mallinckrodt Pharmaceuticals announced Aug. 24 it has reached an agreement to sell its nuclear imaging business to IBA Molecular (IBAM) for $690 million.

Scientists utilize RNA to map neural networks

An innovative use of RNA sequences has allowed scientists from Cold Spring Harbor Laboratory to track connections between individual neurons in the brain, according to a study published in Neuron. Invented by Professor Anthony Zador, MD, PhD, the technique is called Multiplexed Analysis of Projections by Sequencing (MAPseq). 

MRIs show Parkinsonian diseases cause unique decline in functional brain activity

A new study allowed researchers to get a look at the way Parkinson’s disease patients’ brains changed over the course of a year through functional MRI scans. The changes observed through fMRI scans of multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) patients’ and healthy controls’ brains were different across the groups.

 
Mediterranean diet may delay Alzheimer's

There’s a mountain of evidence showing that the traditional Mediterranean diet reduces the risk of heart disease, but a new UCLA study suggests that it can slow the progression of Alzheimer’s as well.

Researchers view live synapse formation for the first time

Researchers have designed a method to visualize the formation of new synapses in mice using photon imaging, according to a study published in the August issue of Science. The technique could uncover information critical to developing new therapies for developmental disorders, according to co-author Hyung-Bae Kwon, PhD.

Study pinpoints region of the brain heavily affected by Parkinson's

Researchers have pinpointed regions in the brain that are affected by Parkinson’s disease, opening the door to a potential treatment.

Image-based predictor of dementia in patients with Down syndrome

Neural biomarkers could be used to predict the risk for dementia in individuals with Down Syndrome, according to a University of Kentucky study.

First imaging of brain epigenetics achieved with new PET radiochemical

Harvard researchers have developed a novel PET radiotracer that can reveal genetic expression, or lack thereof, in the brain enzymes called histone deacetylases (HDACs). 

Brain protein could be preventive measure against Alzheimer’s, new study suggests

As effective treatments for Alzheimer’s continue to elude the medical community, new research from Iowa State University has shed light onto a particular protein and how it can predict the likelihood of someone developing Alzheimer’s.
