Latest X-ray computed tomography Stories

Connie K. Ho for RedOrbit.com The U.S. Food and Drug Administration (FDA) recently announced a proposal to encourage X-ray manufacturers to consider children’s safety in the development of new imaging devices. The FDA is recommending that manufacturers who create new X-ray imaging devices include protocols and instructions for use on pediatric patients. The draft proposal by the FDA also advocates that companies who cannot demonstrate safe and effective use of the X-ray imaging...

Five Examples Culled From The Choosing Wisely Campaign YONKERS, N.Y., May 8, 2012 /PRNewswire-USNewswire/ -- When should patients say "Whoa!" to their doctors? Consumer Reports has some answers in a new follow-up report to the Choosing Wisely campaign launched in April by the ABIM Foundation. The coalition of nine physician groups compiled lists of "Five Things Physicians and Patients Should Question" to represent each doctor group. It's been estimated that up to 30 percent...

Unnecessary imaging was recommended in a significant number of studies but referring physicians often did not adhere to PET/CT report recommendations Advanced imaging has been identified as one factor that contributes to the overall rising cost of healthcare in the US. Unnecessary or inappropriate imaging utilization magnifies the cost burden associated with advanced imaging studies like MRIs and PET/CT scans. Though these studies often provide the best clinical information for making a...

Cervical spine CT examinations are unnecessary for emergency department (ED) patients who are a victim of "simple assault" or who have a "ground-level fall", unless the patient has a condition that predisposes the patient to spine fracture, a new study finds. The study, conducted at Grady Memorial Hospital by researchers from the Department of Radiology and Imaging Sciences of the Emory University School of Medicine in Atlanta, found that out of 218 exams for simple assault, there were...

(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 right...

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...

Low dose whole body CT is nearly four times better than radiographic skeletal survey, the standard of care in the U.S., for determining the extent of disease in patients with multiple myeloma, a new study shows. The study, conducted at the University of Maryland in Baltimore, included 51 patients who had both a radiographic skeletal survey as well as a low dose whole body CT examination. The total number of lesions detected in these patients with low dose whole body CT was 968 versus 248...

The use of a dedicated pediatric imaging department (with dedicated pediatric computed tomography (CT) technologists) for pediatric CT scans significantly reduces the radiation dose delivered to the patient, according to a study in the May issue of the Journal of the American College of Radiology. When performed and monitored properly, the benefits of CT scans outweigh the potential long-term risk of radiation. To minimize the potential adverse effects of radiation exposure to pediatric...

Young patients who undergo chest or abdominopelvic CT are more than 35 times more likely to die of their disease than develop a radiation induced cancer, according to an analysis of 23,359 patients, some of whom were scanned more than 15 times. The analysis conducted at three hospitals in Boston, found that in the chest CT group, 575 out of 8,133 patients were deceased after a mean follow-up of about 4 years. "That compares to the 12 cases of radiation-induced cancer that would be expected...
