Increasing daily physical activity may help older adults delay their progression to Alzheimer’s disease (AD), according to research published July 16 in JAMA Neurology.  

“Our multicenter study found that 4D flow MRI provided a promising way of measuring blood flow in the superior and inferior caval veins and right heart, which may provide further insight into physiologic and pathologic blood flow patterns in individuals with COPD and emphysema,” wrote researchers in a July 24 Radiology study.

New research published July 23 in JAMA reported neurological differences in several areas of the brain, including white matter volume, among U.S. government personnel involved in a 2016 auditory attack in Cuba compared to healthy controls.

“The differences that we observed indicate the strong possibility that there are sex differences in the structural and functional connections in the brain, which may contribute to women’s increased risk for Alzheimer’s,” said Sepideh Shokouhi, at the Alzheimer’s Association International Conference in Los Angeles.

Gadolinium-based contrast agents (GBCAs) are central to MRI exams, providing critical information unavailable with other modalities. However, some patients experience acute adverse reactions, and investigators of a recent study published in Radiology set out to get a clearer picture of these events.

Can a virtual world instill the same level of knowledge in radiology students as a traditional face-to-face classroom approach? Researchers of a new study published in the American Journal of Roentgenology think so.

Contrast-enhanced spectral mammography (CESM) can be a helpful method to screen for postoperative breast cancer when paired with traditional mammography, according to research published July 6 in Clinical Radiology.

A new ultrasound method called passive cavitation imaging (PCI) can create an image estimating the amount of a drug that has crossed the blood-brain barrier (BBB), according to new research conducted at Washington University in St. Louis.

Dynamic contrast-enhanced (DCE) MRI can help measure the permeability of the blood-brain barrier (BBB) in areas of the brain associated with migraines, potentially providing insight into the debilitating headaches and other neurovascular disorders.

“Medical M.R.I.s can do great characterization of samples, but not at this small scale," said A. Duke Shereen, director of the MRI Core Facility at the Advanced Science Research Center in New York, to the New York Times.

Teenagers with large amounts of white matter depicted on brain scans are more likely to up their alcohol intake over the next five years, reported authors of a new study published July 2 in eLife.

PET brain imaging using a new brain imaging paradigm yields preliminary evidence that tobacco smokers may have reduced neuroimmune function compared with non-smokers.
