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 From Junior Seau, former San Diego Chargers linebacker, to Dave Duerson, former Chicago Bears safety—who both committed suicide as a result of chronic traumatic encephalopathy (CTE)—traumatic brain injuries (TBIs) have been making disturbing headlines at an alarming rate. In the United States alone, TBIs account for an estimated 1.6 million to 3.8 million sports injuries every year, with approximately 300,000 of those being diagnosed among young, nonprofessional athletes. But TBIs are not confined to sports; they are also considered a signature wound among soldiers of the Iraq and Afghanistan wars. http://medicalxpress.com/news/2013-03-scoring-win-win-concussion-diagnostic-tools.html Health Tue, 26 Mar 2013 09:00:02 EST news283505853 Monitoring the hepatic function of unresectable liver cancer patients, measured by 99mTc-labeled iminodiacetic acid (HIDA) via single-photon emission computed tomography (SPECT) prior to and during radiation therapy, provides vital information that could guide more customized treatment plans and reduce risks of liver injury, according to research being presented at the 2013 Cancer Imaging and Radiation Therapy Symposium.
