Radiation dose reduction has moved to the forefront of importance in medical imaging with new techniques being developed in an effort to bring doses down as low as possible. What difference can these techniques make? Researchers at Indiana University School of Medicine aimed to find out. http://medicalxpress.com/news/2013-04-iterative-reconstruction-longitudinal-dose-modulation.html Cancer Wed, 17 Apr 2013 00:00:01 EST news285354249 It is unnecessary to scan trauma patients based on a non-focused standard trauma CT protocol, if the patient is transferred for care after already undergoing a focused CT examination based on the patient's history and physical examination, a new study shows. http://medicalxpress.com/news/2013-04-standard-ct-protocol-trauma-patients.html Cancer Mon, 15 Apr 2013 00:00:01 EST news285143636 (HealthDay)—Increasing numbers of U.S. children undergo diagnostic imaging tests such as MRIs and CT scans, and higher-radiation tests account for a growing proportion of these procedures, researchers report. http://medicalxpress.com/news/2012-12-kids-high-radiation-scans.html Cancer Mon, 03 Dec 2012 15:00:02 EST news273753371 Researchers reviewing the records of approximately 250,000 women enrolled in an integrated healthcare delivery system found that increased CT utilization between 2000 and 2010 could result in an increase in the risk of breast cancer for certain women, including younger patients and those who received repeat exams. According to the study, which was presented today at the annual meeting of the Radiological Society of North America (RSNA), nuclear medicine examinations may also contribute to increased breast cancer risk. http://medicalxpress.com/news/2012-11-breast-cancer-prior-ct-nuclear.html Cancer Tue, 27 Nov 2012 00:00:02 EST news273174702 According to an article in the November issue of the Journal of the American College of Radiology, a medical imaging facility in San Diego, Imaging Healthcare Specialists, has implemented a successful radiation dose reduction program, reducing radiation exposure by up to 90 percent in some patients. http://medicalxpress.com/news/2012-11-imaging-facility-successful-dose-reduction.html Cancer Mon, 05 Nov 2012 16:33:49 EST news271355623 An automated lung nodule matching program can improve radiologists' efficiency almost two-fold, a first of its kind study shows. http://medicalxpress.com/news/2012-06-lung-nodule-software-radiologists-efficiency.html Cancer Tue, 26 Jun 2012 13:37:20 EST news259936632 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. http://medicalxpress.com/news/2012-05-simple-assault-ground-fall-require.html Cancer Thu, 03 May 2012 03:10:01 EST news255232240 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. http://medicalxpress.com/news/2012-05-ct-induced-cancer-minimal-dying-disease.html Cancer Tue, 01 May 2012 03:05:07 EST news255060289 About one-third of CT examinations performed following an inconclusive abdominal ultrasound examination have positive findings, according to a study of 449 patients at Massachusetts General Hospital in Boston. http://medicalxpress.com/news/2012-04-benefit-follow-up-ct-abdominal-ultrasound.html Cancer Mon, 30 Apr 2012 02:40:01 EST news254971168 Imaging has been identified as one of the key drivers of increased healthcare costs. A new study from Brigham and Women's Hospital and Harvard Medical School has found significant variation in the use of head computed tomography (CT), even within a single emergency department. Strategies to reduce such variation in head CT use may reduce cost and improve quality of care. The study appears online in advance of publication in the April issue of The American Journal of Medicine. http://medicalxpress.com/news/2012-03-evidence-based-unnecessary-imaging.html Health Fri, 09 Mar 2012 04:41:06 EST news250490456 An article in the January issue of the Journal of the American College of Radiology summarizes methods for radiation dose optimization in pediatric computed tomography (CT) scans.
