Neuroimaging

Neuroradiology is a branch of medical imaging focused on spotting abnormalities of the central and peripheral nervous system, spine, head and neck. These highly trained doctors use CT, MRI, X-ray and other techniques to diagnose strokes, tumors, aneurysms and other neurological conditions.

An example of a positive amyloid plaque PET nuclear brain scan. these tests can help identify Alzheimer's patients earlier so they can be prescribed drugs to treat the condition.

Common markers of Alzheimer's disease visualized on PET scans of asymptomatic patients might foreshadow the onset of symptoms in the years following their initial discovery.

The study, which was published in Brain and Behavior, found that individuals who used their smartphone excessively displayed different strengths in the prefrontal and parietal neural network.

Researchers involved in the study suggested that, until now, this sort of growth acceleration in adolescents had only been observed in children who had experienced extreme adversity, such as violence, neglect and family dysfunction. 

The study's authors explained how MRI results can be used to help identify children with ADHD—and how these findings could be used in the AI algorithms of tomorrow. The team will be presenting its findings at RSNA 2022 in Chicago.

The regions that displayed the most significant differentiations in susceptibility values are known to be associated with neurological conditions such as fatigue, insomnia, anxiety, depression, headaches and other cognitive issues—all common complaints among many COVID long haulers. 

The findings were also found to be associated with the severity of symptoms in individuals with ASD.

Researchers recently presented a new method that considers how already existing lesions grow over time as an indicator of disease progression.

Vessel wall imaging—an MRI technique that offers high resolution images of the vessel wall—may hold clues as to the mechanisms by which COVID infections continue to cause neurologic symptoms after initial recovery in some patients.  

Brain Scan

In the case of a convicted murderer, a New York neuro specialist cited a slew of neuroimaging findings that indicate “severe dysfunction” that could have numbed the defendant’s “brakes of inhibition.” 

The preliminary results of a new study published in the medRxiv preprint server highlight variances in fetal brain development based on mothers’ perceived stress during the onset of COVID.

Compared to a group of patients who had not been previously diagnosed with Lyme disease, those who had been infected displayed unusual activity in the frontal lobe of the brain on functional MRI scans.

Using MRI imaging, the experts found that patients who experienced functional seizures had thinning in the superior temporal cortex and thickening of the left occipital cortex.
