Plastic surgeons have long debated the mechanisms aging-related changes in the face: Are they related more to “deflation” or “sagging”? A new study helps settle the debate, showing significant loss of volume in the upper lip in older adults, reports the February issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS).
The use of MRI to determine heart function has been slow to catch on, but a study from Duke Health researchers shows that stress cardiac MRI not only diagnoses disease, but can also predict which cases are potentially fatal
Medical processes like imaging often require cutting someone open or making them swallow huge tubes with cameras on them. But what if could get the same results with methods that are less expensive, invasive and time-consuming?
A new, more sensitive method to measure ultrasound may revolutionize everything from medical devices to unmanned vehicles. Researchers have combined modern nanofabrication and nanophotonics techniques to build the ultra precise ultrasound sensors on a silicon chip.
Radiation therapy often is used to treat cancer patients. Now, doctors have shown that radiation therapy — aimed directly at the heart — can be used to treat patients with a life-threatening heart rhythm. They treated five patients with irregular heart rhythms, called ventricular tachycardia, who had not responded to standard treatments. The therapy resulted in a dramatic reduction in the number of ventricular tachycardia episodes.
