Machine learning helps experts identify ADHD biomarkers on MRI scans

Experts have identified numerous white matter features, in addition to changes in white matter tracts that occur over time, which they believe are more common among people with ADHD.

mammography mammogram breast cancer

Age, race and density status influence AI performance on mammogram reads

Although studies have shown AI to be effective as a support tool, several have also highlighted issues related to the potential for bias in algorithms that have not been trained on diverse datasets. 

time-delayed MRI phases improve brain tumor visualization

Using multiple MRI phases after contrast injection significantly improves visualization of brain tumors

Researchers are proposing making additional phases beyond the 10-minute mark mandatory when analyzing brain metastases.

AI software improves diagnosis of lung conditions when contrast cannot be used

New software could improve diagnosis of lung conditions for patients who cannot tolerate contrast dye

The machine learning-based software uses a formula called the Integrated Jacobian Formulation to calculate lung volume based on metrics derived from imaging taken during inhalation and exhalation.

Head CTs could present an opportunity to screen for osteoporosis

In individuals who have not completed a DEXA scan, head CT conducted for other reasons can offer insight into patients’ frontal bone density, a potential marker of osteoporosis.

depression and alcohol lead to impairment in functional connectivity of the brain

Combined, alcohol dependence and depression cause 'severe and extensive' brain connectivity impairment

Alcohol dependence and depression are known to affect the functional connectivity of the brain, but when the two co-occur, connectivity between certain regions is significantly worse, new MRI study shows.

medical imaging carbon emissions climate change

PET is an energy hog, but relatively rare utilization lessens its carbon footprint. MRI and CT have no such ‘out’

Medical imaging machinery uses a lot of power, and the extent to which it quickens the pace of global warming is becoming clearer.
