Photoacoustic imaging quantifies elasticity
In photoacoustic imaging, laser pulses are employed to locally heat tissue, which emits ultrasound as a result; the properties of the tissue affect the optical absorption, and hence the appearance of the final ultrasound image. The technique has been tested on skeletal muscle in a human.

CDC Updates Guidance for Care of Zika Babies
The previous guidance recommended performing a cranial ultrasound unless prenatal ultrasound results from the third trimester demonstrated no abnormalities of the brain. The updated guidance recommends a cranial ultrasound even if the prenatal ultrasound was normal.

Ultrasound for Drying Clothes? Maybe Soon.
Scientists from Oak Ridge National Laboratory and GE have already developed ultrasound technology that they say could make clothes dryers 70 percent more energy-efficient than they are now, while also taking half the amount of time to get the job done.

The Thyroid Cancer Epidemic - Just Overdiagnosis?
A report by the WHO International Agency for Research on Cancer shows that the growing epidemic of thyroid cancer reported in recent decades in several high-income countries is largely due to overdiagnosis.

ARCTIC Trial - ultrasound in the follow-up of patients with early rheumatoid arthritis not justified
Objective: To determine whether a treatment strategy based on structured ultrasound assessment would lead to improved outcomes in rheumatoid arthritis, compared with a conventional strategy. The trial results indicate that ultrasound did not significantly improve on conventional assessment.

Ultrasound can levitate large objects
The trick was to create a standing wave in the gap between the transducers and the object, instead of the usual pressure node between the transducer and a reflector.

USA ultrasound payments in 2017 to drop under CMS' proposed rates
Although on average payment rates would increase by 1.6 percent, reorganization of payment rules could result in many ultrasound studies being bundled with surgery or other treatment and not paid separately.

Comparison of the Accuracy of Nurse-Performed and Physician-Performed Lung Ultrasound in the Diagnosis of Cardiogenic Dyspnea
Study results demonstrated comparable accuracy of nurse-performed LUS, suggesting this technique should be used in the emergency room setting when a trained physician is not readily available.

Low frequency ultrasound applied to forearm reduces blood pressure
A research study found that patients' blood pressure and pulse rates were significantly reduced after both 800kHz and 500kHz ultrasound sessions compared to pre-treatment levels. The mechanism of the efect is still unclear.
