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.

Non-invasive ultrasound method prevents aberrations of ultrasound wavefronts

In conventional ultrasounds, variations in soft tissue structure distort ultrasound wavefronts. They blur the image and can hence prove detrimental to medical diagnosis.

Rice researchers create tiny, magnetically-powered neural stimulator

Rice University neuroengineers have created a tiny surgical implant that can electrically stimulate the brain and nervous system without using a battery or wired power supply.

Mini tumors predict how cancer responds to heat treatment

Hyperthermia has shown promise in the treatment of cancer in previous studies. Now, in a new study by scientists at The Institute of Cancer Research, London, the researchers tested the effects of a combination of heat and radiation on mini tumors grown in a spheroid, where cells are placed in a three-dimensional structure. The research is published in the journal Scientific Reports.

Novel 3D imaging technique could prove to be valuable for wide range of studies

A collaboration between Colorado State University and University of Illinois at Urbana-Champaign resulted in a new, 3D imaging technique to visualize tissues and other biological samples on a microscopic scale, with potential to assist with cancer or other disease diagnoses.

Deep vein clots in critical COVID-19 illness

A new research paper published in the journal JAMA Network Open in May 2020 reports a high incidence of deep vein clots in patients with severe COVID-19 at a single French medical center. This could indicate the need for systematic anticoagulant therapy in these patients as a preventive measure.

Doxycycline is not effective in reducing the growth of abdominal aortic aneurysm

A new landmark study by researchers at the University of Maryland School of Medicine (UMSOM) found that patients with a vascular condition, called an abdominal aortic aneurysm, received no benefits from taking a common antibiotic drug to reduce inflammation.

New technique offers high-resolution 3D view inside tumors

Malignant tumors consume nutrients and oxygen faster than healthy cells. To do so, they recruit blood vessels in their environment. Depending on tumor type and genetic profile, there are differences on how tumors look internally.

Children with COVID-19 presenting with sudden severe lung disease

Even as the COVID-19 pandemic continues to seek out new victims, puzzling new presentations are further confusing the situation. A new study published online in The Lancet Rheumatology in May 2020 reports a case of severe COVID-19 in a child who rapidly developed acute respiratory distress symptoms without prior respiratory symptoms. This case should alert clinicians to consider this diagnosis in children as well.

Lung ultrasound use in COVID-19 patients

One point of discussion is the best approach to imaging infected patients, because computed tomography (CT) scanning, the gold standard method for chest imaging, can spread infection due to the need to transport the patient to specialized facilities.

Capillary leakage important in COVID-19 respiratory distress

Now, a new study published on the preprint server medRxiv reports the pivotal role played by protein leakage through lung capillaries and promotes the use of serum albumin as a biomarker of disease progression and severity.

New algorithms support doctors in making a faster and accurate diagnosis

The know-how from the world's top experts in lung ultrasound was collected and organized in the software application.

New noninvasive ultrasound neuromodulation technique for epilepsy treatment

Epilepsy is a central nervous system disorder characterized by recurrent seizures resulting from excessive excitation or inadequate inhibition of neurons.

New imaging device can help detect early biomarker of Alzheimer’s disease

Biomedical engineers at Duke University have devised a new imaging device capable of measuring both the thickness and texture of the various layers of the retina at the back of the eye.

New technique could revolutionize treatment for Alzheimer's, epilepsy, brain tumors

University of Virginia researchers are pioneering the use of focused ultrasound to defy the brain's protective barrier so that doctors could, at last, deliver many treatments directly into the brain to battle neurological diseases.

Obesity, type 2 diabetes, or high blood pressure in teenagers may lead to prematurely aged arteries

Teenagers who have obesity, type 2 diabetes or high blood pressure may be more likely to have signs of premature blood vessel aging compared to teens without those health conditions, according to new research published today in the Journal of the American Heart Association, an open access journal of the American Heart Association.

Cytokine storms created by COVID-19 could be reduced by using blood filter

Cytokine storms created by COVID-19 are causing major organ destruction and death, and for the first time in the United States, when patients begin to show signs of trouble, physicians are replacing the usual filter in a kidney dialysis machine with a filter known to trap these tiny proteins, with the goal of avoiding the devastation.

Using photoacoustic imaging to visualize scarring in donor kidneys before transplant

When kidney transplants first came into practice in the 1950s, patients with chronic kidney disease could finally picture freedom from the unrelenting routine of blood-cleansing dialysis treatments. Just over a half-century later, demand has completely outstripped supply.

Study explores impact of simultaneous alcohol and cannabis usage on unborn children

An unforeseen consequence of normalization of marijuana use is that adolescents and adults of childbearing age are increasingly engaged in a practice of Simultaneous Alcohol and Cannabinoid (SAC) use, or co-ingestion.

New study highlights the need to adopt healthy lifestyles from an early age

A large study in adolescents and children, some as young as 3 years of age, shows a link between obesity, high blood pressure, and later damage to blood vessels. The research is presented today on EAPC Essentials 4 You, a scientific platform of the European Society of Cardiology.
