(Ivanhoe Newswire) — X-rays have changed the way we look at medicine and strong technology is allowing us to make the process safer each year. A new study shows Cone beam CT is superior to mutidetector CT for detecting a small hole in the bony wall of the inner ear bone that can cause dizziness and hearing loss, and it uses half the radiation dose. The study, conducted in Bruges, Belgium, included 21 patients who had both a cone beam CT and a multidetector CT examination of their...

Cone beam CT is superior to mutidetector CT for detecting superior semicircular canal dehiscence or the so called third window (a small hole in the bony wall of the inner ear bone that can cause dizziness and hearing loss) and it uses half the radiation dose, a new study shows. The study, conducted in Bruges, Belgium, included 21 patients who had both a cone beam CT and a multidetector CT examination of their right and left temporal bones, said David Volders, MD, one of the authors of the...

(Ivanhoe Newswire) -- A new study reveals current or heavy smokers who were screened with low-dose spiral computed tomography (CT) scanning had a 20-percent reduced risk of death from lung cancer when compared to patients who were screened via chest X-ray. Researchers enrolled 53,454 men and women in the National Lung Screening Trial (NLST). Participants had either a current or former smoking history of at least 30 pack-years and did not have any symptoms of lung cancer. They were randomly...

A special type of CT scan can help detect lung cancer early in smokers, reducing their mortality rates by 20-percent versus chest X-rays, a new National Cancer Institute (NCI) study has found. The results come from the National Lung Screening Trial (NLST), a national study of more than 53,000 adults between the ages of 55 and 74, all of whom were currently heavy smokers, or had been previously in their lives. They were also required to have a smoking history of at least 30 "pack-years"--a...

A national study of more than 53,000 current and former heavy smokers has demonstrated that helical CT scanning reduced lung cancer deaths by 20 percent compared to using chest X-rays. Constantine Gatsonis and colleagues at Brown's Center for Statistical Sciences contributed methodologic expertise and leadership throughout the study, which began in August 2002. In a major new study announced today by the National Cancer Institute, researchers including Brown University biostatistian...

A new approach to processing X-ray data could lower by a factor of ten or more the amount of radiation patients receive during cone beam CT scans, report researchers from the University of California, San Diego. Cone beam CT plays an essential role in image-guided radiation therapy (IGRT), a state-of-the-art cancer treatment. IGRT uses repeated scans during a course of radiation therapy to precisely target tumors and minimize radiation damage in surrounding tissue. Though IGRT has improved...
