The study will be published in the December issue of the AJR. http://www.physorg.com/news175330807.html Medicine & Health Wed, 21 Oct 2009 08:30:01 EST news175330807 A substantial percentage of children who get CT scans after apparently minor head trauma do not need them, and as a result are put at increased risk of cancer due to radiation exposure. After analyzing more than 42,000 children with head trauma, a national research team led by two UC Davis emergency department physicians has developed guidelines for doctors who care for children with head trauma aimed at reducing those risks. http://www.physorg.com/news172216911.html Medicine & Health Tue, 15 Sep 2009 08:00:01 EST news172216911 A new study published in the September issue of The Journal of Nuclear Medicine shows that positron emission tomography (PET)/computer tomography (CT) scans with the imaging agent choline could detect recurring prostate cancer sooner than conventional imaging technologies in some patients who have had their prostates surgically removed. In addition, the journal also includes a paper that provides a broader examination of new agents and techniques for imaging prostate cancer, which accounts for 10 percent of all cancer-related deaths in the United States and is the most common type of cancer among men. http://www.physorg.com/news171039124.html Medicine & Health Tue, 01 Sep 2009 16:20:01 EST news171039124 A new study found a small but significant number of patients received dangerously high doses of radiation from medical imaging tests, putting them at higher risk for cancer -- sometimes needlessly. http://www.physorg.com/news170614337.html Medicine & Health Thu, 27 Aug 2009 18:40:06 EST news170614337 Patients with possible appendicitis are typically evaluated using a standard-dose contrast enhanced CT, but a low-dose unenhanced CT that delivers approximately 50% less radiation is just as effective, according to a study performed at the Seoul National University College of Medicine in Seoul, Korea. The standard-dose enhanced CT scan delivers approximately 8.0 mSv of radiation; the low-dose unenhanced CT scan delivers approximately 4.2 mSv of radiation. http://www.physorg.com/news167478569.html Medicine & Health Wed, 22 Jul 2009 12:50:01 EST news167478569 (PhysOrg.com) -- Thanks to the skills of artists who work on cold case investigations, people have a chance to see what the Oriental Institute`s mummy Meresamun may have looked like in real life. http://www.physorg.com/news164918693.html Other Sciences Mon, 22 Jun 2009 20:50:01 EST news164918693 (AP) -- Paleontologists say a 75-million-year-old turtle fossil uncovered in southern Utah has a clutch of eggs inside, making it the first prehistoric pregnant turtle found in the United States. http://www.physorg.com/news161026326.html Other Sciences Fri, 08 May 2009 18:32:23 EST news161026326 An effort is under way at the University of Houston to use technologies with origins in the automobile industry to develop new tools that will help doctors and technicians better plan radiation therapy for patients with head and neck cancer. http://www.physorg.com/news160820797.html Medicine & Health Wed, 06 May 2009 09:27:23 EST news160820797 Physicians should review a patient's CT imaging history and cumulative radiation dose when considering whether to perform another CT exam, according to researchers at Brigham and Women's Hospital, Boston, MA, and Washington University School of Medicine, St. Louis, MO. http://www.physorg.com/news160761039.html Medicine & Health Tue, 05 May 2009 16:51:13 EST news160761039 Dr. Hisao Asamura and his team of researchers at The National Cancer Center Hospital in Tokyo, Japan examined the records of 2,281 patients who underwent lung cancer resection surgery between 2000 and 2006. The study was published in the May issue of the Journal of Thoracic Oncology, the official journal of the International Association for the Study of Lung Cancer.

The tumor on his kidney was the size of a baseball by the time his cancer was detected in a CT scan - five years after his doctor misdiagnosed his symptoms and failed to order the right tests. http://www.physorg.com/news155750938.html Medicine & Health Sun, 08 Mar 2009 17:09:29 EST news155750938 University of Washington researchers have helped develop a new kind of microscope to visualize cells in three dimensions, an advance that could bring great progress in the field of early cancer detection. The technique could also bridge a widening gap between cutting-edge imaging techniques used in research and clinical practices, researchers said. http://www.physorg.com/news153412007.html Medicine & Health Mon, 09 Feb 2009 14:40:34 EST news153412007 Most stroke patients can't recall when their symptoms started or do not arrive at the hospital in a timely manner, so they cannot be considered for time-dependent therapies such as the clot-busting drug tissue plasminogen activator (tPA), researchers reported in Stroke: Journal of the American Heart Association. http://www.physorg.com/news137390729.html Medicine & Health Fri, 08 Aug 2008 05:05:29 EST news137390729
