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...

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...

New imaging parameters rein in incremental radiation dose from potentially life-saving CT-guided biopsy of lung nodules to reduce patients' overall exposure New guidelines for CT-guided biopsies of lung nodules significantly reduce radiation exposure allowing individuals the benefit of the procedure, which may cut down on overall lung cancer deaths. This research is being presented at the Society of Interventional Radiology's 37th Annual Scientific Meeting in San Francisco, Calif. "The...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
