Pitting ultrasound against MRI at detecting and grading tears of the common extensor tendon in patients with chronic lateral epicondylitis—aka “tennis elbow”—researchers in Poland have found the former is fine at screening for high-grade tears. However, when any tear is clear on ultrasound, MRI should be considered to precisely assess the extent of the injury, they conclude.

Work is underway at UC-San Francisco to develop an augmented-reality system for planning oncologic interventions using 3D models. The models are not 3D printouts, as you might expect. They’re 3D holograms created from patients’ CT scans and superimposed, a la Pokémon Go, in real-world settings.

When otherwise normally functioning adults with pronounced sleep problems and a weakened sense of smell also have two imaging biomarkers—reduced dopamine activity on SPECT and Parkinson’s-type pattern expression on FDG-PET—they’re probably headed for full-on Parkinson’s disease.

Prior research has shown that the human brain responds similarly to desired substances of abuse as to cute babies’ faces, with both cues triggering the release of dopamine-based brain rewards. A new functional MRI study has documented that the baby-face response is markedly muted in mothers who have substance addictions—even when the babies are their own.

The source and cause of gastrointestinal bleeding can be notoriously difficult to pinpoint, but French researchers have found 64-slice multiphasic, multidetector CT up to the job. Diagnostic and Interventional Imaging published the team’s findings online June 25.

The New York Times has posted a vivid photo essay on a new JAMA study detailing a grim pathology finding for football fans: Of 111 deceased NFL players whose brains were checked for chronic traumatic encephalopathy, all but one came back positive.

A fourth-year medical student who logged 10 years as an EMT, paramedic and volunteer firefighter is encouraging peers in his previous field to embrace point-of-care ultrasound for use in the field.

Researchers at Japan’s National Defense Medical College have developed an ultrasound-equipped photoacoustic imaging (PAI) system that shows potential for imaging the angiogenesis, or formation of troublesome new blood vessels, in prostate cancer.
