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.

High-intensity ultrasound waves heats and destroys uterine fibroids

A totally noninvasive procedure using high-intensity ultrasound waves to heat and destroy uterine fibroid tissue significantly relieves fibroid-related symptoms in women, according to the results of a multicenter clinical trial.

Low-fat diet early in life improves heart health in men

New research has apparently added to the growing belief that early dietary interventions can improve cholesterol levels in children.

Alagebrium may prevent arterial aging in patients with systolic hypertension

A compound called alagebrium, which is very similar to another used in anti-wrinkle creams, may be useful in reducing the deleterious effects of arterial aging in the majority of elderly Americans with systolic hypertension, a new study from researchers at Johns Hopkins shows.

Liver transplants may not be suitable for all cystic fibrosis patients

A new study on patients with cystic fibrosis (CF) who have had abnormal bleeding from ruptured blood vessels in the esophagus (variceal hemorrhage) as a result of liver disease found that transplant may not be indicated if there are no other indications of advanced liver disease.

MRI to detect magnetic probes of tiny iron oxide particles successfully tracks implanted cells in cancer patients

By using MRI to detect magnetic probes of tiny iron oxide particles, an international research team for the first time has successfully tracked immune-stimulating cells implanted into cancer patients for treatment purposes.

Brains of babies born very prematurely do not develop as well as those who are carried to full-term

"We found that in very premature babies, a part of the brain doesn't show normal growth after birth, and in fact some parts of the brain didn't change at all from the day the babies were born until they reached what would have been a full-term birth date."

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.
