RT radiation dose to pancreas linked to adult diabetes risk
August 24, 2012 -- Childhood cancer survivors whose treatment included abdominal radiotherapy (RT) have an increased risk of developing diabetes. Now, a study published online August 23 in Lancet Oncology has narrowed the location of radiation dose vulnerability to the tail of the pancreas.
New takes on image guidance for radiation therapy
August 24, 2012 -- Kilovoltage and megavoltage conebeam CT are predominantly used for real-time imaging during radiation therapy, with systems based on ultrasound or MRI now also being developed. But there are other imaging modalities that could be used, including those that offer functional and molecular information regarding the tumor being treated.
Radiologists vary DR image quality to optimize radiation dose
August 24, 2012 -- A new Chinese study questions the assumption that striving for the highest possible image quality is always the best approach. Researchers developed an x-ray optimization strategy that cuts the dose of digital radiography (DR) substantially by adjusting dose levels based on the type of exam being conducted.
CMS releases final rule for stage 2 meaningful use
August 23, 2012 -- The U.S. Centers for Medicare and Medicaid Services (CMS) has released its final rule for stage 2 meaningful use, which now includes the viewing of medical images as a menu item in the U.S. government's healthcare IT stimulus program.
NYU Langone sets high goals with new PET/MRI scanner
August 23, 2012 -- For NYU Langone Medical Center, the acquisition of a new PET/MRI scanner was a no-brainer. From a clinical perspective, the hybrid modality's ability to simultaneously image metabolic and physiological functions provides a platform for the facility to expand its research capabilities and offer better care for patients.
Breast tomosynthesis: If you build it, they will come
August 23, 2012 -- Digital breast tomosynthesis isn't in the experimental phase anymore -- it's now beginning to help practices build volume and reduce recall rates, according to a presentation given last week at the annual AHRA meeting in Orlando, FL.
Canadian head CT guidelines beat New Orleans criteria
August 22, 2012 -- In a head-to-head contest between guidelines for assessing mild head injury, researchers in Tunisia found that the Canadian CT Head Rule was more accurate than the New Orleans Criteria in predicting the need for neurosurgical intervention, according to a report published online in Annals of Emergency Medicine.
MRI scans undercut stenosis theory for multiple sclerosis
August 22, 2012 -- MRI has shown that changes in brain blood flow associated with vein abnormalities are not specific for multiple sclerosis and do not contribute to the affliction's severity, according to a study published online August 21 in Radiology.
Coronary calcium tops list of heart disease predictors
August 21, 2012 -- Elevated coronary artery calcium as detected on CT scans is the most important among several predictors of cardiovascular events over time, according to a new analysis of more than 1,000 patients published in the Journal of the American Medical Association.
