CT data shows high rates of emphysema among marijuana users

Radiologists should take note of these findings as the drug's popularity and legalization continue to climb.

Collaborators from a number of international centers, led by the European Molecular Biology Laboratory-European Bioinformatics Institute, published their findings Wednesday in Nature. Using MRI scans, along with morphology and genetic data, they showed that this network of heart muscle fibers—known as the trabeculae—can influence the heart’s performance.

Thousands of MRI scans help experts understand 500-year-old heart mystery first described by Leonardo da Vinci

Artificial intelligence also played a large role in discovering how this intricate network of muscle fibers can influence health, experts explained in Nature.

ADHD medication can negatively impact child brain development

A commonly prescribed drug used to treat attention-deficit/hyperactivity disorder (ADHD) disproportionately affects the development of children’s brains compared to adults with ADHD, according to a new study published in Radiology.

Rejected scientific rad articles: Destiny depends on rejecters’ input vs. lack thereof

Tracking the fate of 200 unsolicited manuscripts rejected in one calendar year by the American Journal of Roentgenology, a researcher has found that the majority—117 manuscripts, close to 60 percent—eventually found a home in other scientific journals, according to an analysis running in the June edition of that very journal.

When does worrisome architectural distortion signal malignancy on mammography?

Architectural distortion, the non-mass but potentially ominous clinical feature observed in many breast imaging procedures, is less likely to signal malignancy when it’s detected on screening mammography rather than diagnostic mammography or when it does not correlate with a subsequent targeted ultrasound exam.

Functional MRI (fMRI) image measuring the strength of connectivity in particular brain circuits before and after subjects were given either a 20-milligram oral dose of methylphenidate used to treat ADHD or a placebo. The scans showed that methylphenidate strengthened connectivity between several brain regions involved in regulating emotions and exerting control over behaviors.

Imaging Addiction: Could PET & MR End Cocaine Abuse?

Cocaine addiction can ruin a person physically and financially, and with an estimated 1.4 million cocaine users in the U.S., thousands will become trapped by their habit. While previous research on the drug and its addictive potential were observational and subjective, imaging is reshaping how we see addiction—and how it will be treated.

PET technique visualizes amyloid deposits in heart

PET with 11C-PIB provides a noninvasive method for visualizing amyloid deposits in the heart, according to a study published in the February issue of the Journal of Nuclear Medicine. The researchers suggest that 11C-PIB eventually may be used in the clinical setting as both a diagnostic tool and a treatment follow-up method.

Automated AI-generated measurements combined with annotated CT images can improve treatment planning and help referring physicians and patients better understand their disease, explained Sarah Jane Rinehart, MD, director of cardiac imaging with Charleston Area Medical Center.

Two advanced algorithms—one for CAC scores and another for segmenting cardiac chamber volumes—outperformed radiologists when assessing low-dose chest CT scans. 

"Gen AI can help tackle repetitive tasks and provide insights into massive datasets, saving valuable time," Thomas Kurian, CEO of Google Cloud, said Tuesday.
