Focused Ultrasound Thalamotomy Reduces Essential Tremor
For patients with essential tremor (ET), unilateral focused ultrasound thalamotomy improves contralateral hand tremor, avoids use of an operating room and invasion of the skull, and requires only minimal recovery time, giving it some advantages over deep-brain stimulation (DBS), researchers report.

Super-resolution vascular imaging demonstrated in rat brain
The technique involves ultrasound imaging at more than 500 frames per second and use of a microbubble contrast agent. It produces sub-wavelength structural imaging and haemodynamic quantification of cerebral vessels less than ten micrometres in diameter at depths up to 10mm.

New head scanning ultrasound technology could save soldier lives
The new software-based approach uses conventional ultrasound imaging and a movement sensor attached to the transducer to build a 3D image of the brain. The system is designed to be used by an individual with only basic training and the dataset can be sent to a remote reading site.

Ultrasound guidance for femoral artery catheterization superior to palpation technique in pediatric patients.
"Ultrasound-guided femoral arterial cannulation in children when performed by anesthesia residents is superior to the palpation technique based on the reduction of the time taken for attempted cannulation and the number of attempts, and improvement in first attempt success," the authors wrote.

Ultrasound Opens the Brain to Promising Drugs
The brain’s built-in protection system, the blood-brain barrier, also prevents potentially lifesaving drugs from getting in, but maybe not for much longer. A French neurosurgeon has used an implantable ultrasound device to open the blood-brain barrier to treat glioblastoma with chemotherapy.
