Up to two-thirds of thyroid ultrasound examinations will reveal nodules, though only a small percentage prove to be malignant. Fine-needle aspiration cytology (FNAC) can help distinguish between malignant and benign tissue, but the test is not cost-effective in every case.

Despite what countless click-bait advertisements may promise, “one simple hack” rarely changes your life. But a new imaging technology from Duke University Health System may pack plenty of potential for changing ultrasonic capabilities.

A new study conducted by a team of researchers led by Michel Grothe of the German Center for Neurodegenerative Diseases in Rostock, Germany, announced the development of a four-stage model of regional amyloid beta (Aβ) protein deposition that can be found in patients with Alzheimer's, according to an article by Alzforum. 

Longer gestation during normal pregnancy is associated with significantly greater development of white matter in babies’ brains. However, similar associations are no longer present by the time children are 8 years old. The lack may confirm that white-matter development in the brains of preemies tends to catch up as these children grow.

The National Sleep Foundation recommends seven to nine hours of shuteye per night for adults between 26 and 64. Using functional MRI, researchers at Japan’s National Institute of Mental Health in Tokyo have shown why getting less often leads to bad moods and poor emotional health.

MRI may help head off underage drinking

Teens aren’t going to like this: Neuro MRI has helped researchers accurately predict which young persons are likely to become heavy drinkers by the time they turn 18. If readily replicable, the work may suggest modes of pre-problem intervention.

MR-guided brain ultrasound helps rouse coma patient back to consciousness

Neuroscience researchers and clinicians at UCLA have used MR-guided ultrasound to help rouse a recovering coma patient to a more alert state of consciousness. 

New zinc-focused MRI technique can ID cancerous prostate tissue

Distinguishing between healthy and cancerous cells just might be the biggest hurdle in cancer care physicians have encountered. A new MRI technique developed by radiologists at UT Southwestern Medical Center in Dallas have fixed that problem using zinc.

fMRI brain study unpacks, predicts sentence-level verbal expression

Researchers have used functional MRI (fMRI) to come up with a way to predict neural patterns produced by words within sentences. Building on previous studies that focused on single words lighting up parts of the brain, the team correctly anticipated brain-activity patterns at the sentence level to the tune of 70 percent accuracy, on average.

fMRI shows kids’ brains lighting up for unhealthy foods pushed on TV

Neuroscience isn’t needed to know that food commercials influence children’s choices of what to eat and how determinedly to demand it. If those ads for sugary, fatty, high-sodium, low-fiber and fun-to-eat products didn’t work, the food and beverage industry wouldn’t be spending $2 billion per year to create and place them.  

Study: More radiotherapy can cut mortality risk in half

Researchers have found patients with high-risk prostate cancer who are treated with a high portion of radical local treatment (radiotherapy or prostatectomy) have half the mortality risk of those who were treated with the lowest proportion.

Study uses MRI to show thirst is an anticipatory reflex

For the first time ever, researchers say they’ve uncovered the mechanism for short-term thirst and thirst quenching, according to a new article in the journal Nature.

 
When teaching radiology, don’t forget to embrace the unknown

Most articles in today’s radiology journals focus on specific case studies or problems facing the industry. A recent editorial published in the Journal of the American College of Radiology, however, really caught my eye by taking a deeper, more philosophical approach.

4D lung imaging platform gives clearer vision for early detection

Professor Andreas Fouras of Monash University has developed a four-dimensional lung scanning technology platform, helping physicians to detect abnormal lung functions early, reports News Medical.

PET imaging gives insight into a brain with depression

Scientists from the RIKEN Center for Life Science Technology (CLST) have developed a new PET scan that is able to analyze neuron proliferation in the brain's subventricular and subgranular zones of the hippocampal dentate gyrus, the areas most affected by depression.
