High-intensity Ultrasound Helps to Wipe Out Cancer Cells Anywhere in the Body

A new study has found that an intense form of ultrasound that shakes a tumor until its cells start to leak can launch an attack on cancer.

The study led by researchers at Duke University's Pratt School of Engineering has suggested that a high intensity ultrasound can activate an “alarm” that enlists immune defenses against the cancerous invasion.

The new findings from animal experiments imply that once triggered by the ultrasound, the immune system might even search for and devastate cancer cells, including those that have spread through the bloodstream to lurk in other parts of the body.

British sonographers move to stamp out occupational MSK injuries

The Society of Radiographers in the U.K. has published a guidance to help prevent work-related musculoskeletal disorders, the most common work-related illness in Britain.

Studies have repeatedly shown that radiographers and other healthcare professionals who carry out sonography examinations are at particularly high risk of suffering painful conditions affecting the back, shoulders, neck, and arms. These include tendinitis, carpal tunnel syndrome, and tenosynovitis.

"Too many sonographers are being made ill by their work and, in some cases, have to retire because of disabling repetitive strain injuries," said Kim Sunley, the health and safety officer for the Society of Radiographers.

Increasing volumes of work and demanding work schedules within some organizations, exacerbated by staff shortages and the pressures of working in a target-driven environment, may have an impact on the prevalence of musculoskeletal disorders among sonographers, according to the report.

Ultrasound to Diagnose Down's Syndrome Questioned

(Ivanhoe Newswire) -- A leading expert in the field of ultrasound research is questioning the usefulness of obstetric ultrasound to diagnose Down's syndrome.

Hylton Meire, an ultrasound expert and consultant radiologist in England, raised the possibility the procedure is not as useful as has been suggested, and he emphasized there is lack of scientific data to support the practice.
