Latest X-ray computed tomography Stories

Computed tomography (CT) utilization in pediatric patients with non-traumatic abdominal pain increased in emergency departments each year between 1999 and 2007, according to a new study published online in the journal Radiology. The study authors found no corresponding increase in ultrasound use during the same period, despite research supporting it as an important diagnostic tool for assessing pediatric abdominal pain. Non-traumatic abdominal pain is a common source of pediatric visits to...

First of its kind actuarial analysis from health insurance payor perspective provides real world analysis of actual costs and lives saved annually WASHINGTON, April 9, 2012 /PRNewswire-USNewswire/ -- Legacy® and Lung Cancer Alliance hailed the results released today of an actuarial cost-benefit analysis conducted by Milliman Inc., an internationally recognized actuarial consulting firm, which show that screening 50-64 year olds at high risk for lung cancer with low-dose computed...

A group of US researchers has quantified the amount of radiation obese patients receive when undergoing routine medical scans. Results published today, 6 April, by IOP Publishing in the journal Physics in Medicine & Biology, have shown that, when undergoing a CT scan, a forced change of operation parameters for obese patients results in an increase of up to 62 per cent in organ radiation exposure compared to lower weight patients. The researchers, from Rensselaer Polytechnic...

Engineering Researchers at Rensselaer Polytechnic Institute Develop “Phantoms” To Make Medical Imaging Safer for Overweight Individuals Most medical imaging equipment is not designed with overweight and obese patients in mind. As a result, these individuals can be exposed to higher levels of radiation during routine X-ray and CT scans. A new study from Rensselaer Polytechnic Institute is the first to calculate exactly how much additional radiation obese patients receive from a CT...

The secondary cancer risk from multi-detector computed tomography (MDCT) scans is low among older adults, according to a study from Stanford University in the April issue of the Journal of the American College of Radiology. MDCT is a high-speed imaging technique that is commonly used to diagnose a variety of diseases and conditions. Evidence shows that MDCT scanning offers important benefits through more accurate diagnosis and better disease management in a range of medical disorders....

Patients with inflammatory bowel disease (IBD) and other gastrointestinal (GI) disorders may be exposed to significant doses of diagnostic radiation, according to a new study in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association. "Our results show that significant increases in radiation exposure in the last decade have paralleled the increased use of computed tomography imaging," said Alan N. Desmond, MB, BMedSc, MRCPI, of the...

Study shows CT scans are less costly way to identify patients with chest pain who do not have coronary artery blockage Cardiac computed tomography angiography scans (CT scans that look at the heart) can provide a virtually instant verdict on whether chest pain is from blockage of the coronary arteries. When used early to evaluate chest pain, the scans save patients and hospitals time and money by allowing doctors to quickly determine who should be admitted for treatment for a heart attack...

A highly detailed CT scan of the heart can safely and quickly rule out the possibility of a heart attack among many patients who come to hospital emergency rooms with chest pain, according to the results of a study that will be presented by researchers from the Perelman School of Medicine at the University of Pennsylvania today at the American College of Cardiology's 61st Annual Scientific Session and published concurrently in the New England Journal of Medicine. The multicenter randomized...
