Tau levels found in concussed former athletes may help predict who will ultimately suffer from long-term effects of blows to the brain, according to a new study published in Neurology.

Four-dimensional (4D) CT can reliably evaluate ligament injuries in the ankle and may be used to test the ankle in-motion to spot asymptomatic problems, according to results of a May 8 study published in Clinical Radiology.

"Our findings suggest that patients with higher prechemotherapy DHEAS levels had lower odds of developing self-perceived cognitive impairment,” wrote authors of a study published in Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy.

"The global obesity pandemic has not only led to a greater incidence of cardiovascular disease and type 2 diabetes, but has also coincided with a rise in brain diseases, such as accelerated cognitive decline and dementia,” wrote authors of an April 23 study published in Radiology.

Dopamine transporter (DAT) SPECT may be a useful imaging biomarker to determine the severity of Parkinson’s disease, according to an April 17 study published in the American Journal of Roentgenology.

International researchers have created a new ultrasound probe capable of delivering more precise treatment to women with gynecological cancers, reported authors of a feasibility study published in the Journal of Medical Imaging.

Clinicians can use optical coherence tomography angiography (OCTA) to noninvasively diagnose patients with early cognitive impairment, an early indicator of Alzheimer’s disease (AD), reported authors of a single-center study published in PLOS One.

Going by a small study published online March 22 in European Radiology, biplanar digital radiographs of the hip joint reconstructed in 3D as well as 2D are sufficiently comparable on coverage assessments with similarly rendered CT scans to justify the reduction in radiation dose as well as in, presumably, the cost of image acquisition.

Research presented at this year’s Society of Interventional Radiology conference in Austin, Texas, suggests virtual reality (VR) could be useful to interventional radiologists, improving treatments using real-time 3D images from inside a patient’s vessels.

It’s well established that widely used CPAP devices help give a good night’s rest to people with obstructive sleep apnea. Now an MRI-based study has shown the breathing assistance provided by continuous positive airway pressure also increases blood flow to, and blood volume in, the brain. 

Researchers can more accurately and comprehensively study the brain with a novel concept known as diattenuation imaging (DI)—a neuroimaging method that allows scientists to measure the polarization-dependent attenuation of light throughout different parts of the brain—according to a study published in Scientific Reports.

On scans from several different MRI techniques, regular alcohol consumption correlates with regional changes in the brain as well as with various cognitive abilities. And those most sensitive to alcohol’s viewable and observable effects are men and individuals whose faces blush upon intake.
