High-tech heart scans fail in some cases to detect artery blockages and at other times can misidentify blockages that don't exist, a study found. The study provoking debate among cardiologists indicates further that the more invasive, standard testing procedure is not ready to be replaced by the newer technology, researchers say. Researchers said in this week's New England Journal of Medicine that supported computer tomography or CT scans can be beneficial in identifying needed treatment,...

ATLANTA - A long-awaited federal study of an X-ray alternative to the dreaded colonoscopy confirms its effectiveness at spotting most cancers, although it was far from perfect. Medicare is already considering paying for this cheaper, less intrusive option that could persuade more people to get screened for colon cancer. And some experts believe the new method may boost the 50 percent screening rate for a cancer that is the country's second biggest killer. "We're talking about for the first...

A U.S. study suggests computed tomographic colonography is an effective, less invasive option in screening for colorectal cancer. CT colonograpy uses virtual reality technology to produce two- or three-dimensional visualizations of the colon and rectum and is less invasive than standard colonoscopy, which uses a long tube with a camera to view the lining of the colon, researchers said. The results of the American College of Radiology Imaging Network National CT Colonography Trial, which...

Some people are undergoing computed tomography scans who don't need the tests, doctors in San Francisco say. Dr. Rita Redberg, a cardiologist at the University of California-San Francisco, said some medical officials continue to use CT heart scans on individuals who have not had any chest pains, The New York Times reported Saturday. No data suggests that there's any reason for anyone asymptomatic to have a test, Redberg said. There certainly is this idea that having a test can help you...

By Helen Branswell, Medical Reporter, THE CANADIAN PRESS TORONTO - Wait times for MRI and CT scans in Ontario - and probably elsewhere in Canada - could be reduced by cutting back on unnecessary scans ordered by doctors, a new study suggests. The work, an analysis of why scans were ordered and what treatment course was followed based on the results, suggests more rational use of the machines should be considered. "I think all of Canada is experiencing challenges with wait times. And I...

SACRAMENTO, Calif., Dec. 15 /PRNewswire/ -- Sacramento HeartScan has announced that preventive imaging holiday gift certificates for heart, lung and whole body scans are available. "If you're having difficulty with last-minute shopping, this is definitely something to consider," said Dr. Raye Bellinger of Sacramento HeartScan. "As unusual as it might seem, these gifts convey a great deal of care for those that are closest and most important to us. The preventive imaging scans are also...

Two minor changes in technique could make a major difference in the radiation dose used in survey CT scans, a new study shows. Survey scans are those that are performed before a regular CT scan, usually to plan for the examination. The radiation dose in a survey scan can be as high as that of four chest X-rays, said Dianna D. Cody, PhD, associate professor in the department of imaging physics at The University of Texas, M.D. Anderson Cancer Center in Houston, TX. The radiation dose depends on...

The costly procedure won't significantly boost life expectancy, expert says HealthDayNews -- It sounds like a good idea: Regular computed tomography (CT) scans of the entire body, looking for aberrations that might signal early signs of disease. But a new study suggests these scans -- which cost about $900 apiece -- do little to boost long-term health, and might even undermine patient care. The study found that whole-body scans added just six days of life expectancy to the average 50-year-old...
