Opening a Door into Cells: Research Shows How Ultrasound Can Deliver Therapeutic Molecules into Living Cells
Researchers have shown how ultrasound energy can briefly "open a door" in the protective outer membranes of living cells to allow entry of drugs and other therapeutic molecules - and how the cells themselves can then quickly close the door. view more (2006-09-06)
More biogas, less sludge
Germany has more than 10,000 sewage plants, using costly processes to treat household, industrial and restaurant waste water. The treated water is discharged back into river and lake systems. What remains is an organic / inorganic mixture of sludge. The issue is how to dispose of this residue. Up to now, sewage sludge has been used as an... view more... (2002-11-14)
Sewer sensors examine the parts the inspectors cannot reach
A remote control sensing device is being developed to detect defects in sewer walls. Using both ultrasound and laser light, digital information on the condition of the sewer walls is fed back to a computer which can be programmed to spot problems. The research is being carried out by a team in the Department of Mechanical Engineering at King's... view more... (2002-10-10)
3-D ultrasound scanner could guide robotic surgeries
Duke University engineers have shown that a three-dimensional ultrasound scanner they developed can successfully guide a surgical robot. view more (2006-10-31)
Breast cancer treatment procedure gives women more options
A new minimally invasive approach to partial breast irradiation provides another treatment option for women with breast cancer. The researchers presented their findings today at the annual meeting of the Radiological Society of North America. view more (2006-11-30)
NEW DIAGNOSTIC METHOD COULD IMPROVE DETECTION OF PROSTATE CANCER (p 1849)
A new diagnostic technique using colour Doppler with an ultrasound contrast agent is more effective than conventional systematic biopsy in diagnosing prostate cancer, conclude the authors of a research letter in this week's issue of THE LANCET. Prostate cancer detection is currently based on three diagnostic tests: serum prostate-specific antigen... view more... (2001-06-06)
Tiny 3-D ultrasound probe guides catheter procedures
An ultrasound probe small enough to ride along at the tip of a catheter can provide physicians with clearer real-time images of soft tissue without the risks associated with conventional x-ray catheter guidance. view more (2008-08-29)
Noninvasive tests for cirrhosis may help to avoid liver biopsy
Newer ultrasound and magnetic resonance (MR) imaging tests yield encouraging initial results in diagnosing fibrosis (scarring) and cirrhosis of the liver, according to three studies in the October issue of the journal Clinical Gastroenterology and Hepatology. view more (2007-10-02)
Detailed echoes from inside the body
In the early days of medical ultrasound, physicians only saw shadowy outlines of the structures inside the body. Today's techniques are not only capable of providing still and moving images of very high resolution. They can be used to measure the rate of blood flow or even discern signs of hardening of the arteries: Where the walls of the blood... view more... (2003-03-11)
Ultrasound shown to exert remote control of brain circuits
In a twist on nontraditional uses of ultrasound, a group of neuroscientists at Arizona State University has developed pulsed ultrasound techniques that can remotely stimulate brain circuit activity. view more (2008-10-30)
Groundbreaking, inexpensive, pocket-sized ultrasound device can help treat cancer, relieve arthritis
A prototype of a therapeutic ultrasound device, developed by a Cornell graduate student, fits in the palm of a hand, is battery-powered and packs enough punch to stabilize a gunshot wound or deliver drugs to brain cancer patients. view more (2008-12-22)
Researchers propose new ultrasound screening criteria for diagnosing polycystic kidney disease
Modification of the current screening criteria are needed for diagnosing patients with autosomal dominant polycystic disease (ADPKD), according to a study appearing in the January 2009 issue of the Journal of the American Society Nephrology (JASN). The results suggest that some patients with a milder form of the disease may otherwise be... view more... (2008-10-22)
First steps toward autonomous robot surgeries
The day may be getting a little closer when robots will perform surgery on patients in dangerous situations or in remote locations, such as on the battlefield or in space, with minimal human guidance. view more (2008-05-07)
Research yields new clues to how we locate objects in space
Two mechanisms have been commonly described which allow us to locate objects in space. Direct perception occurs when we see, hear or feel an object; by directly looking at an object, for example, we can easily describe its size, shape and where it is located in space. view more (2009-01-13)
MRI Superior to Mammography for Screening Women at High Risk for Breast Cancer
Magnetic resonance imaging (MRI) of the breast is significantly more sensitive than mammography and ultrasound for diagnosing familial breast cancer, according to researchers at Germany's University of Bonn. view more (2003-06-12)
Rotator cuff treatment provides immediate tendonitis relief
A minimally invasive procedure to treat tendonitis in the rotator cuff of the shoulder provides immediate symptom relief to the patient. view more (2009-06-30)
Simple ultrasound exam may predict osteoporosis risk
An ultrasound exam of the heel may be able to predict if a woman is at heightened risk for fractures due to osteoporosis, according to a new multicenter study being published in the July issue of the journal Radiology. view more (2008-06-24)
Potential for noninvasive brain tumor treatment
Duke University engineers have taken a first step toward a minimally invasive treatment of brain tumors by combining chemotherapy with heat administered from the end of a catheter. view more (2009-06-17)
Ultrasound may help regrow teeth
Hockey players, rejoice! A team of University of Alberta researchers has created technology to regrow teeth—the first time scientists have been able to reform human dental tissue. view more (2006-06-29)
Anti-tumor therapy with endoscopic ultrasound may fight cancer more safely and effectively
The chairman of EUS2008 today announced that investigational research on a therapeutic technique that will allow physicians to directly inject malignant tumors with cancer fighting agents from inside the body will be presented at the 16th International Symposium of Endoscopic Ultrasonography (EUS2008) in San Francisco on September 12-13. view more (2008-09-12)
