Ultrasound fusion imaging provides comparable accuracy for bone, soft tissue tumors

Ultrasound fusion imaging provides comparable accuracy for bone, soft tissue tumors
2011-02-17
(Press-News.org) DETROIT – Biopsies using ultrasound fusion imaging for detecting bone and soft tissue cancers are safe, effective and just as accurate as conventional biopsy methods, according to a Henry Ford Hospital study.

Researchers found that the ultrasound fusion imaging technique guides a needle biopsy with precise accuracy and ease, while making the biopsy experience more convenient for patients.

Ultrasound fusion merges real-time ultrasound images with previously acquired computed tomography or magnetic resonance imaging scans, providing physicians with high resolution, life-like imaging to identify the area for biopsy.

This is the first time researchers compared the safety and efficacy of ultrasound fusion against conventional biopsy imaging tools like CT or MRI.

The study's findings will be presented at the annual meeting of the American Academy of Orthopaedic Surgeons Feb. 15-18 in San Diego.

"Ultrasound fusion is a viable option to consider for patients," says Michael Mott, M.D., an orthopaedic oncologist at Henry Ford and principal investigator for the study. "With imaging precision being equal, patients liked the ultrasound fusion because scheduling a biopsy was found to be more flexible for ultrasound suites than CT suites."

Bone and soft tissue cancers account for a small number of cancer cases. According to the National Cancer Institute, about less than 1 percent of all new cancer cases occur each year in the United States.

Henry Ford researchers compared the results of 44 patients from January to December in 2010 who were randomized into one of two groups: those who received an ultrasound fusion biopsy and those who received a CT biopsy. Researchers also looked at the time and ease of obtaining the biopsy and outcomes.

Dr. Mott says the accuracy for obtaining the ultrasound fusion biopsy was 93 percent compared to 90 percent for obtaining the CT biopsy. Researchers also found that the ultrasound fusion was as safe and effective as the CT biopsy.

The study was funded by Henry Ford Hospital and GE Healthcare.

Customized knee replacement depends on surgeon's skill, not implant design

Customized knee replacement depends on surgeons skill, not implant design
2011-02-17
DETROIT – While the choices of knee implants are plentiful, the success of total knee replacement surgery still is dependent on the surgeon's skill, Henry Ford Hospital researchers say. Researchers found that utilizing a series of common but nuanced surgical techniques is far more important to customizing the fit of a patient's implant than the implant's design. The findings will be displayed at the annual meeting of the American Academy of Orthopaedic Surgeons Feb. 15-18 in San Diego. "Customized knee implants will not replace the need for precise, methodical surgical ...

Oldest fossils of large seaweeds, possible animals tell story about oxygen in an ancient ocean

Oldest fossils of large seaweeds, possible animals tell story about oxygen in an ancient ocean
2011-02-17
Almost 600 million years ago, before the rampant evolution of diverse life forms known as the Cambrian explosion, a community of seaweeds and worm-like animals lived in a quiet deep-water niche under the sea near what is now Lantian, a small village in Anhui Province of South China. Then they simply died, leaving some 3,000 nearly pristine fossils preserved between beds of black shale deposited in oxygen-free waters. Scientists from the Chinese Academy of Sciences, Virginia Tech in the U.S., and Northwest University in Xi'an, China report the discovery of the fossils ...

New pneumococcal vaccine approach successful in early tests

2011-02-17
Pneumococcus (Streptococcus pneumoniae) accounts for as much as 11 percent of mortality in young children worldwide. While successful vaccines like Prevnar® exist, they are expensive and only work against specific pneumococcal strains, with the risk of becoming less effective as new strains emerge. Through a novel discovery approach, researchers at Children's Hospital Boston and Genocea Biosciences, Inc., in collaboration with the international nonprofit organization PATH, developed a new vaccine candidate that is potentially cheaper and able to protect against any pneumococcal ...

Who's the boss? Americans respond faster to those with high social status

2011-02-17
Who do you look at in a group photo? If you're like most adults, you'll look at yourself first — unless your boss is also in the picture. A study in PLoS ONE by researchers from the Brain and Creativity Institute at USC and Peking University examines how White Americans and Chinese people in China respond to pictures of their boss, suggesting cultural differences in our responses to authority figures. Unlike people in China, who responded fastest to pictures of their direct supervisor, White Americans responded faster to pictures of their own face than to pictures of ...

GW researchers reveal first autism candidate gene that demonstrates sensitivity to sex hormones

2011-02-17
WASHINGTON— George Washington University researcher, Dr. Valerie Hu, Professor of Biochemistry and Molecular Biology, and her team at the School of Medicine and Health Sciences, have found that male and female sex hormones regulate expression of an important gene in neuronal cell culture through a mechanism that could explain not only higher levels of testosterone observed in some individuals with autism, but also why males have a higher incidence of autism than females. The gene, RORA, encodes a protein that works as a "master switch" for gene expression, and is critical ...

Mio-Pliocene faunal exchanges and African biogeography: The record of fossil bovids

2011-02-17
New fossil discoveries have provided a glimpse into the biogeographic configuration of Africa over the last seven million years. Modern-day Africa south of the Sahara is home to a unique variety of mammals, a great number of which are not found anywhere else in the world. Biogeographers have long recognized that sub-Saharan Africa constitutes one of the world's six major mammalian biogeographic divisions, termed 'realms'. However, the historical development of these continental regions of biogeographic diversity has been little explored. Description of six million-year-old ...

Biological anthropologists question claims for human ancestry

2011-02-17
"Too simple" and "not so fast" suggest biological anthropologists from the George Washington University and New York University about the origins of human ancestry. In the upcoming issue of the journal Nature, the anthropologists question the claims that several prominent fossil discoveries made in the last decade are our human ancestors. Instead, the authors offer a more nuanced explanation of the fossils' place in the Tree of Life. They conclude that instead of being our ancestors the fossils more likely belong to extinct distant cousins. "Don't get me wrong, these ...

Key culprit identified in breast cancer metastasis

2011-02-17
When doctors discover high concentrations of regulatory T cells in the tumors of breast cancer patients, the prognosis is often grim, though why exactly has long been unclear. Now new research at the University of California, San Diego School of Medicine suggests these regulatory T cells, whose job is to help mediate the body's immune response, produce a protein that appears to hasten and intensify the spread of breast cancer to distant organs and, in doing so, dramatically increase the risk of death. The findings are reported in the Feb. 16 advance online edition ...

Regrowing hair: UCLA-VA researchers may have accidentally discovered a solution

Regrowing hair: UCLA-VA researchers may have accidentally discovered a solution
2011-02-17
It has been long known that stress plays a part not just in the graying of hair but in hair loss as well. Over the years, numerous hair-restoration remedies have emerged, ranging from hucksters' "miracle solvents" to legitimate medications such as minoxidil. But even the best of these have shown limited effectiveness. Now, a team led by researchers from UCLA and the Veterans Administration that was investigating how stress affects gastrointestinal function may have found a chemical compound that induces hair growth by blocking a stress-related hormone associated with ...
