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.

Stem cells to repair heart tissue soon after a heart attack

Stem cells derived from human heart tissue develop into multicellular, spherical structures called cardiospheres that express the normal properties of primitive heart tissue, smooth muscle and blood vessel cells, according to a study by Johns Hopkins researchers.

New screening test can predict Down syndrome in first trimester

According to new research, an early blood test has proven to be an accurate predictor for Down syndrome.

Ultrasound to view heart's interior in three dimensions

Duke University engineers are developing technology that may enable physicians to someday use high frequency ultrasound waves both to visualize the heart's interior in three dimensions and then selectively destroy heart tissue with heat to correct arrhythmias.

Ultrasound to treat cancer

For the first time, ultrasound is being used in animal models – to treat cancer by disrupting tumor blood vessels.

Space ultrasound training program for non-physicians

An ultrasound training program for non-physicians gives astronauts and sports trainers the tools to assess injuries using real-time remote assistance from medical experts.

Unique approach to enhance the immune system in patients with breast or colorectal cancer

The study uses a potent immune-enhancing gene delivered directly into the cancer cells to make them look foreign to the body's immune system, which will then attack and destroy the cancer.

As men grow older, bladder function can worsen and the prostate gland may be responsible

Their findings remind patients and their physicians that urination difficulties in men can be better cared for at early onset. Additionally, the study notes that as men age, the possibility increases that they will experience problems with urination.

Single blast of ultrasound destroys cancer cells

Scientists at the University of Dundee have demonstrated that cancer cells can be targeted and destroyed by a single blast of ultrasound according to an article published in leading scientific journal "Nature-Physics".

Tissue engineering used to reconstruct defective tracheas (windpipes) in fetal lambs

Researchers at Children's Hospital Boston report using tissue engineering to reconstruct defective tracheas (windpipes) in fetal lambs, first using cells from the amniotic fluid to grow sections of cartilage tube, and then implanting these living grafts into the lambs while still in the womb.

Minimally invasive needle breast biopsies and sentinel node biopsies should be performed more routinely than they currently are

Physicians should strive to replace traditional, invasive procedures for diagnosing breast cancer with proven, less-invasive diagnostic methods, according to an international panel of breast cancer experts convened at the Keck School of Medicine of the University of Southern California.

Speeding up fetal MRIs

A modified technique that uses the eyes as the line of reference means a 50 percent reduction in the time necessary to take MRI images of the fetal brain.

MRI may better enable physicians to plan care for infants with heart defects

Magnetic resonance imaging (MRI) techniques can provide real-time measurements of volume in a fetal heart, and may better enable physicians to plan care for infants with heart defects, according to a new study.

From aircraft aerodynamics to improved heart implants

At first glance airplane wings and human hearts have little in common, but, say a team of European researchers, a technology used to measure airflow over wings can now be used to help keep hearts in working order.

Longer hospital stays do not mean better care

Physicians at The Johns Hopkins Hospital (JHH) have disproved the notion that longer hospital stays mean better care. They have successfully cut back on wait times across one dozen hospital departments and, as a result, reduced to well below six the average number of days patients with congestive heart failure, a need for dialysis or surgery, and many other conditions must spend in the hospital.

Treatment of Nonalcoholic Fatty Liver Disease (NAFLD) in children

The Nonalcoholic Steatohepatitis (NASH) Clinical Research Network has launched its second clinical trial to study NASH, a liver disease that resembles alcoholic liver disease but occurs in patients who drink little or no alcohol. The first trial, launched in January of this year, focuses on adults, while the second trial studies the disease in children.

Combining optical tomography with standard ultrasound imaging can help distinguish early-stage breast cancer

A new study shows that combining a technology called optical tomography with standard ultrasound imaging can help distinguish early-stage breast cancer from non-cancerous lesions--and potentially reduce the number of breast biopsies performed. The study appears in the October issue of the journal Radiology.

Still a long way to go in diagnostic evaluation of all patients who suffer ischemic strokes

Women who survive a stroke are less likely than men to get crucial tests of their heart and neck arteries that can help improve their treatment and reduce their risk of a second stroke, a new University of Michigan study finds.

Enhanced imaging techniques could improve medical diagnosis

Chris Wyatt is a Virginia Tech electrical engineer who is attempting to provide the medical community with better, quicker, and more relevant images of the human body. The side effects are not bad either - lower medical costs, new treatments, and earlier disease detection.

Outcomes of perineal laceration repair following childbirth

Women who have third-or fourth-degree perineal laceration repairs following the birth of their first baby have considerably different outcomes that can adversely impact quality of life and have implications on subsequent deliveries, according to Virginia Commonwealth University researchers.

A preoperative testing strategy may help determine stage of lung cancer more accurately

A preoperative testing strategy combining two procedures may help improve the accuracy of determining the stage of lung cancer, according to an article in the August 24/31 issue of JAMA: The Journal of the American Medical Association.
