Diattenuation Imaging (DI) is a relatively new concept that allows researchers to study the brain more comprehensively and accurately. The neuro-imaging method is a major breakthrough in medical science. A study published in the Scientific Reports states that DI allows scientists to measure polarization-dependent attenuation of light through different parts of the brain. The Study […]

PET Brain Scans Help Connect the Dots between CTE, Tackle Football
The recent discovery of CTE or Chronic Traumatic Encephalopathy in footballers indicates a growing health risk among players. The presence of abnormal brain tissue, referred to as tau protein can be detected only after death. But a recent study published in the New England Journal of Medicine (NEJM) states that PET scans on some living […]
AI and Mental Health Research
Over 45 million people in America alone are coping up some kind of mental illness. The nature and scope of their treatment can also vary tremendously. Can Artificial Intelligence help? AI enabled facial analysis is helping researchers in assessing mental health. In an objective manner, by managing algorithms detecting behavioral biomarkers instead of subjective exams, […]
Malware Tricks Radiologists with Fake Nodules
Researchers based in Israel developed malware to draw your attention to the security lags and weaknesses in medical imaging networks and types of equipment. A malware that could add a real-looking but fake growths to MRI and CT scans or hide real cancerous tumors or nodules that would get detected by any medical imaging equipment. […]
AI under FDA Control?
On April 3, a Tuesday, the FA announced that it is building a new framework that would regulate AI-based medical devices, which learns continually from healthcare data and adapts. Scott Gottlieb, MD, FDA Commissioner announced his resignation last month and released a detailed discussion paper outlining the approach of the administration to pace up with […]
JAMA: Amyloid PET Changes Clinical Management in 60% of Patients with Dementia
Amyloid brain imaging performed with a PET tracer successfully changed clinical management for 60 percent of patients with mild cognitive impairment or MCI and 63 percent of those patients with dementia. According to the Imaging Dementia – Evidence for Amyloid Scanning (IDEAS) study report published in JAMA, this is a new finding. The first phase […]
Perfusion MRI Shows CPAP Healing the Brains of Apnea Patients
Continuous Positive Airway Pressure, or CPAP, induces certain changes in the Mean Diffusivity (MD) and Fractional Anisotropy (FA) in the brain, which indicates microstructural changes. Both occur in language, sensory-motor functions, and cognition. CPAP treatment leads to brain perfusion, which increases cerebral blood flow (CBF) as well as cerebral blood volume (CBV). It is an […]
MRI Study Finds Men, “Blushing Individuals” More Sensitive to Alcohol
According to the reports of research conducted at China’s Shantou University, the findings of which were published in the American Journal of Neuroradiology, March edition, men are more sensitive to alcohol consumption with viewable signs like blushing. Scanning report from different types of MRI techniques shows that regular alcohol intake correlated with certain regional changes […]
Google and Amazon Speaker Assist Interventional Radiologists
If you believed in the limited abilities of smart speakers like Google Home or Amazon Echo, it is time to think again. Doctors are now using these devices to provide better voice-based medical care. During many medical procedures like surgeries, it is often impossible to use computers. In such cases, doctors are relying on voice […]
fMRI and Fetal Gender Brains
Male and female human brains tend to go in separate directions right from the womb. In a recent study published in the April edition of Developmental Cognitive Neuroscience, researchers have revealed that functional connectivity is different between sexes from the very early stages of neurodevelopment. Resting-state functional MRI or fMRI was used to image the […]
