True whole-body field view using PET/CT could allow doctors to more accurately manage cancer patients

2010-11-23
(Press-News.org) When using combined positron emission tomography (PET) computed tomography (CT) imaging, adopting a true whole-body field of view in the imaging of cancer patients could lead to more accurate staging and restaging than achieved with the routinely used limited whole-body field of view, according to a study in the December issue of the American Journal of Roentgenology (www.ajronline.org). PET/CT is a dual imaging technique that is used to diagnose and treat a variety of diseases, including many types of cancers.

"Use of the routine field of view for whole-body FDG PET/CT can lead to underestimation of the true extent of the disease because metastasis outside the typical base of skull to upper thigh field of view can be missed," said Medhat M. Osman, MD, lead author of the study.

The study, performed at Saint Louis University in St. Louis, MO, included 500 patients who underwent true whole-body FDG PET/CT, from the top of the skull to the bottom of the feet. Fifty nine of 500 patients had PET/CT findings suggestive of malignancy outside the limited whole-body field of view. New cancerous involvement was confirmed in 20 of those patients.

"Detection of malignancy outside the limited whole-body field of view resulted in a change in management in 65 percent and in staging in 55 percent of the 20 cases," said Osman.

"Our results show that compared with limited whole-body acquisition, use of true whole-body image acquisition may increase the accuracy of staging, change the treatment of cancer patients, and help in the selection of more accessible biopsy sites, avoiding unnecessary invasive surgical procedures and eliminating unnecessary imaging," he said.

About ARRS

The American Roentgen Ray Society (ARRS) was founded in 1900 and is the oldest radiology society in the United States. Its monthly journal, the American Journal of Roentgenology, began publication in 1906. Radiologists from all over the world attend the ARRS annual meeting to participate in instructional courses, scientific paper presentations and scientific and commercial exhibits related to the field of radiology. The Society is named after the first Nobel Laureate in Physics, Wilhelm Röentgen, who discovered the x-ray in 1895.

MIT study: Adding face shields to helmets could help avoid blast-induced brain injuries

2010-11-23
CAMBRIDGE, Mass. — More than half of all combat-related injuries sustained by U.S. troops are the result of explosions, and many of those involve injuries to the head. According to the U.S. Department of Defense, about 130,000 U.S. service members deployed in Iraq and Afghanistan have sustained traumatic brain injuries — ranging from concussion to long-term brain damage and death — as a result of an explosion. A recent analysis by a team of researchers led by MIT reveals one possible way to prevent those injuries — adding a face shield to the helmet worn by military personnel. In ...

High alpha-carotene levels associated with longer life

2010-11-23
High blood levels of the antioxidant alpha-carotene appear to be associated with a reduced risk of dying over a 14-year period, according to a report posted online today that will be published in the March 28 print issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Oxygen-related damage to DNA, proteins and fats may play a role in the development of chronic diseases like heart disease and cancer, according to background information in the article. Carotenoids—including beta-carotene, alpha-carotene and lycopene—are produced by plants and microorganisms ...

Depression may be both consequence of and risk factor for diabetes

2010-11-23
Diabetes appears to be associated with the risk of depression and vice versa, suggesting the relationship between the two works in both directions, according to a report in the November 22 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. An estimated 23.5 million U.S. adults—more than 10 percent—have diabetes, including 23 percent of those ages 60 and older, according to background information in the article. Major depressive disorder affects about 14.8 million U.S. adults each year. "Although it has been hypothesized that the diabetes-depression ...

Study examines risk of bleeding among patients taking 2 anti-platelet drugs

2010-11-23
Dual antiplatelet therapy—treatment with the medications clopidogrel and aspirin together to prevent blood clots—poses a clinically significant risk of hemorrhage that should be considered before prescribing, according to a report in the November 22 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Dual antiplatelet therapy with clopidogrel plus aspirin is commonly used to prevent blood clots in patients with cardiovascular disease, according to background information in the article. The treatment has demonstrated a benefit in reducing the formation ...

Lower-income families with high-deductible health plans may put off care because of costs

2010-11-23
Lower-income families in high-deductible health plans appear more likely to delay or forgo medical care based on cost than higher-income families with similar coverage, according to a report in the November 22 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. However, lower-income families did not report any more troubles understanding or using their plans. "In the midst of the current economic downturn, many Americans are paying more for their health care," the authors write as background information in the article. "One way in which a growing ...

Exercising to piano music appears to help reduce falls among older adults

2010-11-23
Introducing a music-based multitask exercise program for community-dwelling elderly people may lead to improved gait (manner or style of walking), balance and a reduction in the rate of falling, according to a report posted online today that will be published in the March 28 print issue of Archives of Internal Medicine, one of the JAMA/Archives journals. "Each year, one-third of the population 65 years and older experiences at least one fall, and half of those fall repeatedly," the authors write as background information in the article. "Exercise can counteract key risk ...

Personalized multimedia program may help prevent falls in patients without cognitive impairment

2010-11-23
A patient education program combining videos with one-on-one follow-up did not appear to reduce the risk of falls among all older hospital patients, but was associated with fewer falls among patients who were not cognitively impaired, according to a report posted online today that will be published in the March 28 print issue of Archives of Internal Medicine, one of the JAMA/Archives journals. "Falls are a leading patient safety incident event in general hospitals and are especially common in older patients," the authors write as background information in the article. ...

EDITOR'S PICK: Who is in your poo? Working with mice and human patients, Eric Pamer, Carles Ubdea, and colleagues, at Memorial Sloan-Kettering Cancer Center, New York, have generated data that suggest that high-throughput DNA sequencing of bacteria in the gut could identify patients at high-risk of life-threatening bloodstream infection with the antibiotic-resistant bacterium vancomycin-resistant Enterococcus (VRE). Bacterial infections acquired as a result of treatment in a hospital or health-care unit kill approximately 100,000 people a year in the US. Many of these ...

Allotment gardeners reap healthy rewards

2010-11-23
People who have an allotment, especially those aged over 60, tend to be significantly healthier than those who do not. Researchers writing in BioMed Central's open access journal Environmental Health have shown that the small gardens were associated with increased levels of physical activity at all ages, and improved health and well-being in more elderly people. Agnes van den Berg, from Wageningen University and Research Centre, the Netherlands, worked with a team of researchers to carry out a study into the health benefits of allotment gardening. She said, "Taken together, ...

US death rate from congenital heart defects continues to decline

2010-11-23
The U.S. death rate from congenital heart defects dropped 24 percent from 1999 to 2006 among children and adults, according to research reported in Circulation: Journal of the American Heart Association. A congenital heart defect was the underlying cause of 27,960 deaths — an age-standardized rate of 1.2 deaths per 100,000 people — based on data from death certificates. In a comparable study published in Circulation in 2001, deaths due to congenital heart defects dropped 39 percent from 1979 to 1997. Congenital heart defects are structural abnormalities of the heart ...
