Brain imaging may predict mood, attention disorders in children

Health

Dec. 26 (UPI) -- Brain imaging may help identify children at risk for mood disorders as they grow up, a new study suggests. In findings published Thursday in the journal JAMA Psychiatry, researchers were essentially able to predict attention problems, as well as mood disorders such as depression and anxiety, in young grade school children using functional magnetic resonance imaging, or fMRI. Although additional research is needed to confirm and expand upon these results, the authors told UPI their findings mean that brain imaging could one day be used as a screening tool for these disorders. "A child's brain and behavior change a fair amount over the years," said co-author Silvia Bunge, professor of developmental psychology at the University of California at Berkeley. "A minor issue, suc...

Archaeologists use subsurface imaging to map unmarked graves

Science

April 26 (UPI) -- Archaeologists in Australia are using advanced subsurface imaging technology to help community groups locate and map lost and unmarked graves. "This is a huge issue, particularly for rural communities," Ian Moffat, a research fellow at Flinders University, said in a news release. "Using geophysics provides a non-invasive and culturally appropriate way to map unmarked grave sites." Most recently, Moffat and his research partners used ground penetrating radar, or GPR, and GPS surveys to map unmarked graves at Lake Condah Mission Cemetery, an important site for the Gunditjmara, an indigenous people of southwestern Victoria, a state in Australia. The cemetery, founded in 1869, contains only 26 marked graves, but is estimated to host dozens more unmarked graves. Using GPR, r...

New imaging method could speed up breast cancer diagnosis

Health

Dec. 20 (UPI) -- Researchers at the University of Illinois at Urbana-Champaign have created a new technology to track tumor development within human breast tissue, a study says. The new system has the potential to speed up a normally lengthy process. A traditional cancer diagnosis takes a few days and requires tissue to be removed, dyed with chemicals and examined by a pathologist. This research, published Wednesday in Science Advances, detailed how the portable optical imaging system simultaneously captured images from surgically-removed breast tissue with light pulses in four modalities. The researchers tested their new tool during breast cancer surgeries at Carle Foundation Hospital. They took cancer breast tissue removed from patients and located particular molecular features linked t...

Rapid heart imaging system may improve care in developing nations

Health

Aug. 29 (UPI) -- A rapid imaging system could improve heart healthcare in developing nations because of reduced costs and easier availability, according to a study in Peru. Researchers determined the new system, which uses contrast dye to measure cardiac structure, function and scarring, was effective at a fraction of the costs and time required for the traditional imaging system. The findings were published Wednesday in the Journal of the American Heart Association. In Peru, 16 percent of the population has cardiovascular disease, researchers say, but screening people there for heart conditions can be difficult. The Cardiac Magnetic Resonance Imaging system, also called cardiac MRIs, are often not available for people in Peru and other developing nations. The method provides detailed inf...

Brain imaging shows memory loss differs by age

Health

March 7 (UPI) -- High-resolution brain imaging can be used to show memory proficiency between older and younger adults, according to University of California researchers.Using magnetic resonance imaging, researchers at the University of California, Irvine, found patterns in memory loss during two tests of memory, an object memory task and a location one."This suggests that not all memory changes equally with aging," lead author Zachariah Reagh, who participated in the study as a graduate student at UCI and is now a postdoctoral fellow at UC Davis, said in a press release. "Object memory is far more vulnerable than spatial, or location, memory -- at least in the early stages."As people get older, they often wonder whether its part of the normal part of aging or signs of early stages of a se...
