Ultrasound News and Research

RSS

Ultrasound is a procedure in which high-energy sound waves are bounced off internal tissues or organs and make echoes. The echo patterns are shown on the screen of an ultrasound machine, forming a picture of body tissues called a sonogram. Also called ultrasonography.

Transcranial MR-guided focused ultrasound for brain disorders a step closer

A team of researchers working at the MR-Center of the University Children's Hospital in Zürich has completed a pilot study using transcranial MR-guided focused ultrasound to treat 10 patients with neuropathic pain.

Artificial intelligence used to diagnose metastatic cancer

When doctors are managing care for women with breast cancer, the information available to them profoundly influences the type of care they recommend. Knowing whether a woman's cancer has metastasized, for instance, directly affects how her doctors will approach treatment -- which may in turn influence the outcome of that treatment.
