News Stories
Using intravascular ultrasound in stent implantation improves cardiac outcomes
After one year, patients with long coronary lesions who were implanted with an intravascular ultrasound-guided everolimus-eluting stent had a significantly lower rate of major adverse cardiac events compared with those implanted with an angiography-guided stent.

Ultrasound-mediated oncolytic virus delivery and uptake review
Oncolytic viruses can selectively replicate within and destroy a cancer cell, thus making them a powerful therapeutic in treating late-stage or metastatic cancer. This article reviews current state of the art in delivery via microbubbles and ultrasound.

Ultrasound captures rat brain in microscopic 3D
Scientists in France have developed an ultrasound technique based on microbubble contrast that can rapidly build up a 3D view of a network of blood vessels, in microscopic detail.

UK researchers develop pancreatic cancer treatment 'breakthrough'
The treatment uses oxygen filled microbubbles which have inactive drug attached to the surface, delivered by injection and then burst once inside the tumour by ultrasound waves that also activate the drug...

EC project makes finger scanner for early diagnosis of arthritis
A prototype system based on optoacoustic and hyperspectral imaging has been developed as part of an EC-funded project to give early diagnosis of arthritis of the hands.

Low-intensity continuous ultrasound triggers bisphosphonate anticancer activity
The research study suggests that low-intensity ultrasound has a potential significant role in treating bone mets from breast cancer.


3D Ultrasound Gives Surgical Precision to Anesthesia
This one is interesting because the researchers propose to have a computer "interpret" the images by comparing obtained images in real time against a template, allowing the user to effectively guide injections without actually recognizing what is on the ultrasound screen.

Sciatic Nerve Blockade Using Ultrasound identification of landmark only
A novel methodology for identifying the sciatic nerve before blockade has been developed. That task is often challenging, particularly in morbidly obese patients. Results are mixed, but technique may provide alternative approach to palpation.

MIT Researchers Developing Method for Non-Invasive ICP Measurement Using Ultrasound
The estimate of ICP is based on two measurements: arterial blood flow velocity in the brain and the arterial blood pressure waveform (the complete profile of blood pressure throughout a cardiac cycle).

Grand Challenge Grant-Ultrasound Strain and Time-of-Flight for Diagnosing Pneumonia
Jonathan Rubin of the University of Michigan in the U.S. received a grant to develop a simple, low-cost ultrasound device with cell phone display that can diagnose children with co-existing pneumonia and malnutrition.

Signostics Moves to USA and Picks Up 35 Million Investment
Signostics, a start-up innovator in the field of highly miniaturized ultrasound technology, today announced a private investment of $35 million dollars from KKR, a leading global investment firm.

Evena Medical Launches First Smart Glasses for Clinicians at MEDICA 2015 with Ultrasound for Deep Tissue Vascular Imaging
Evena Eyes-On® Glasses 3.0 Features Patented Wearable Ultrasound as well as Multispectral Light for Vein Detection, Venipuncture

Tricorder-Like Technology Could Provide Contact-Free Ultrasound
Stanford Scientists have developed “tricorder-like” technology using radio frequency and ultrasound to detect embedded objects in highly dispersive materials, such as water, mud, or human tissue. The technology was originally intended to safely locate buried explosives.

Tiny Bubbles plus Ultrasound Turn Water Into Effective Cleaning Tool
The simplicity of ‘Starstream,’ invented by two researchers from the University of Southampton, England, promises to change the way we clean our bodies as well as objects we use, from kitchen tools to medical instruments.

3 imaging procedures linked to medical overuse in 2014
The three were screening for asymptomatic carotid stenosis, screening for diagnostic thyroid cancer—both of which widely use ultrasonography—and head CT.

Could you measure my placenta, please?
Yale researchers have launched a ResearchKit app EPV for pregnant women to track the growth of their baby’s placenta. Researchers are interested in knowing the correlation between Estimated Placental Volume (EPV) and pregnancy outcomes.

New Thyroid Cancer Guidelines Reflect Altered Treatment Landscape
An increase in thyroid cancer diagnoses has led to unnecessary biopsies and surgeries. New guidelines from the American Thyroid Association endorse close observation as a possible treatment option for many small papillary thyroid tumors rather than surgery.

Abdominal Fat Early in Pregnancy Predicts Gestational Diabetes
A prospective cohort study published in Diabetes Care suggests that abdominal adiposity is a predictive marker of gestational diabetes mellitus (GDM) appearing later in pregnancy.

Lawsuit tossed in Florida ultrasound-training case
Last May, three female students in an ultrasound technologist program sued Valencia College in Orlando, Fla., alleging two professors forced them to undergo vaginal sonograms in class. A federal judge has now thrown out the suit.

Adding ultrasound to breast screening results in higher rate of detection for women in Japan
Adding ultrasound to standard mammography tests in breast screening could result in improved rates of detection for breast cancer in women in Japan, according to a new study, published in The Lancet.

Ultrasound Reveals How Speech Sounds Are Formed
The Department of Phonetics at the University of Turku is the first one in the world to combine both ultrasound technology and research on the evoked potentials of the brain in the development of language education.
