Oxygen, the air we breathe and the foundation of life, remains mysterious in terms of seeing it working through our tissues. That is until researchers developed a new tool to show us just how oxygen travels to our tissue.

A radiology team at Virginia Commonwealth University Medical Center is using advanced multiparametric MRI to diagnose difficult prostate cancers with upwards of 90 percent accuracy—and then perform targeted biopsies guided by MRI and ultrasound. 

The new method used to detect androgen receptors and active splice variants could mean better and faster care for patients suffering from prostate cancer. 

Aspect Imaging, a design and producer of MRI systems, have developed an MRI machine that is more compact than many contemporary machines.

A new analysis of big data largely based on thousands of MR and PET images has shown that changes in blood flow to and within the brain precede amyloid build-up in Alzheimer’s patients. 

Amplifying research from earlier this year showing that the anatomic effects of traumatic brain injury persist long after observable symptoms subside—potentially long enough to increase risk for Alzheimer’s—a new diffusion MRI study has shown white matter changes in the brains of athletes six months after a concussion event.  

A new fMRI study has shown how marijuana use dulls neural activity in the nucleus accumbens (NAcc), a key part of the brain’s “reward pathway.” The imaging also captured the effect associating with sluggish anticipatory excitement over the promise of nondrug rewards such as money. 

On the heels of a preclinical study showing that epileptic memory disruptions may be treatable by an implantable neuro device—one that’s yet to be invented—comes a here-and-now success story of an MRI-guided procedure that uses a catheter and laser ablation to fight epileptic seizures at their source in the brain.
