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.

New treatment guidelines for carpal tunnel syndrome

The American Academy of Orthopaedic Surgeons (AAOS) has approved and released an evidence-based clinical practice guideline on "The Treatment of Carpal Tunnel Syndrome."

Nanoparticles target multiple cancer genes, shrink tumors more effectively

Nanoparticles filled with small interfering RNA (siRNA) molecules targeting two genes that trigger melanoma have shown that they can inhibit the development of melanoma, the most dangerous type of skin cancer.

Sensitive ultrasound to spot early-stage cancer

European researchers have developed highly sensitive ultrasound equipment that can detect tiny quantities of reflective microbubbles engineered to stick to specific tumour cells. The technique should pick up tumours early and improve patients' chances of survival.

NanoVibronix receives FDA clearance for PainShield diathermy device

NanoVibronix, a medical device company, announced that the US Food and Drug Administration (FDA) has granted 510K clearance to market PainShield MD, a diathermy device used to treat pain. PainShield is the first hands-free, patch-based diathermy device, thus allowing for an entirely new dimension in ultrasound treatment of pain and soft tissue healing. The PainShield consists of a disposable patch connected to a portable reusable driver and generates ultrasound waves to the desired area of the body.

Vulnerable plaque may be easier to detect through optical coherence tomography

Research results indicate that optical coherence tomography (OCT), a newly evolving imaging method, may be the best tool available to detect vulnerable plaque in coronary arteries. The findings will be presented at the 20th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF).

Olmesartan may reduce coronary artery plaque

Research presented at the 20th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF), suggests that olmesartan, a drug commonly used to treat high blood pressure, may play a role in reducing coronary plaque

Women require less tobacco exposure than men to increase colon cancer risk

While smoking poses a health threat to both men and women, women require less tobacco exposure than men to have a significant increased risk for colorectal cancer, according to new research presented at the 73rd Annual ACG Scientific Meeting in Orlando.

Nanotubes detect tumors and deliver high-potency punch

Researchers at the Center for Cancer Nanotechnology Excellence Focused on Therapy Response (CCNE-TR), based at Stanford University, have found a new way to target cancer cells while leaving healthy cells untouched.

Nanobubbles deliver targeted cancer drugs using ultrasound

Using a combination of polymers that respond to temperature, a research team at the University of Utah has developed a multifunctional nanoparticle that can image tumors using ultrasound and simultaneously deliver cell-damaging energy and anticancer drugs to those tumors. In addition, these nanoparticles appear to act specifically on tumors and not on healthy tissue.

Isoflavone dietary supplement improves the functioning of the arteries in stroke patients

A dietary supplement containing isoflavone - a chemical found in soybeans, chickpeas, legumes and clovers - can improve artery function in stroke patients according to new research published online in Europe's leading cardiology journal, the European Heart Journal today.

World's first hand-held ultrasound imaging device

Siemens Canada Limited has partnered with Vancouver General Hospital (VGH) to implement the new ACUSON P10 ultrasound system - the world's first hand-held ultrasound imaging device - replacing the existing technology.

Heavy snorers at increased risk of stroke

University of Sydney researchers have found that heavy snorers have a higher risk of cholesterol plaque in the neck arteries, leading to an increased risk of stroke.

European guidelines for acute pulmonary embolism

Acute pulmonary embolism (PE) is a relatively common cardiovascular emergency. Clots originating in the leg veins may become detached and obstruct the lung vessels. This obstruction may lead to a rise of pressure in the pulmonary circulation and possibly to life-threatening heart failure.

Heavy snoring a sign of early carotid atherosclerosis

A study in the Sept. 1 issue of the journal Sleep shows that objectively measured heavy snoring is an independent risk factor for early carotid atherosclerosis, which may progress to be associated with stroke.

Intima media thickness of the carotid artery

Both in the clinic and in the research area we look for a toll to identify subjects who will develop cardiovascular disease. Decades of silent arterial wall alterations precede vascular clinical events, which then reflect advanced atherosclerotic disease.
