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.

Following percutaneous interventions for malignant liver lesions, patients are ably assessed with a combination of contrast-enhanced ultrasound (CEUS) and perfusion-imaging software, according to the authors of a study published online September 25 in Ultraschall in der Medizin/European Journal of Ultrasound.

A new ultrasound system for diagnosing breast cancer is among several imaging innovations in the works at the U.K.’s National Physical Laboratory (NPL) in London.

Researchers have demonstrated an automated bone-removal algorithm that works with dual-energy CT to let physicians see, unobstructed by the skull, what’s going on in the brains of patients with intracranial hemorrhage following head trauma.

A task force convened by the International Association for the Study of Pain is warning against the use of neuroimaging in legal cases involving patients who claim they’re living with chronic pain.

A new study featuring 3D CT imaging has shown how bird skulls evolve differently than relatives and ancestors. Instead, they develop more like young dinosaurs and crocodiles.

The cognitive therapy called Attention Process Training-II (APT-II) provides worthwhile benefits to elderly patients with mild cognitive impairment (MCI) who have cerebral small vessel disease and are therefore at heightened risk for dementia.

The finding isn’t likely to sway Katie Ledecky or other swimmers from training for the 2020 Summer Olympics in Tokyo, but a small study at Henry Ford Health System in Detroit has shown that long competitive careers in the pool can saddle these athletes with chronically reduced mechanical properties in muscles and tendons of the shoulder, heightening the likelihood of rotator cuff damage.
