AHRQ summary offers 3 strategies for CIN prevention
August 24, 2016 -- The U.S. Agency for Healthcare Research and Quality (AHRQ) has released a summary of two major evidence reviews on the risks of contrast-induced nephropathy (CIN), stating there are only three proven strategies for preventing CIN.
How low can CT radiation dose go for lung screening?
August 15, 2016 -- We're making progress in the race to reduce radiation dose for CT lung cancer screening to ever-lower levels. But as dose drops, image noise grows. Fortunately, researchers are refining image processing techniques that can improve image quality while driving CT dose down to the level of a chest x-ray.
Article questions long-term health effects of atomic bombs
August 12, 2016 -- A new article published in Genetics questions whether the long-term health effects experienced by survivors of the atomic bombs dropped on Hiroshima and Nagasaki have been as dire as originally predicted.
3D imaging helps diagnose 1.7-million-year-old cancer
August 8, 2016 -- Cancer is often thought to be a product of modern times and lifestyles, but researchers have discovered what they believe is the earliest case of malignancy -- in a fossil from an early human ancestor who lived about 1.7 million years ago. The key to diagnosing this ancient cancer was advanced 3D imaging technology.
6 steps to getting a new CT scanner approved
August 5, 2016 -- Do you need a CT scanner or other capital equipment for your radiology department, but aren't sure how to seal the deal? The road from recognizing a need to powering up that million-dollar machine can be long -- and strewn with potholes that only planning and preparation can fill, according to CT expert Dr. Geoffrey Rubin.
Lung abnormalities at CT linked to in-hospital death
August 3, 2016 -- In critically ill patients, the presence of interstitial lung abnormalities detected on CT scans increases a patient's risk of dying in the hospital, concludes a recent study. But the modality can help by diagnosing more patients and identifying those at greater risk.
Radiation exposure monitoring needs a personal touch
July 28, 2016 -- Yes, good software can go a long way. But it takes people to really make a radiation dose-monitoring initiative successful, according to a July 27 webinar co-sponsored by the Society for Imaging Informatics in Medicine and the European Society of Medical Imaging Informatics.
COPD severity mirrors lung cancer incidence
July 28, 2016 -- A new analysis of patients who participated in the National Lung Screening Trial shows a clear relationship between the severity of chronic obstructive pulmonary disease (COPD) and lung cancer incidence at screening. The findings suggest that COPD patients should be included in CT lung screening programs.
Survey finds CTA use has surged since 2001
July 26, 2016 -- Driven by dramatic growth in chest exams and the number of studies performed in the emergency department, utilization of CT angiography (CTA) exams in the Medicare population has skyrocketed over the past 13 years, according to new research from the Harvey L. Neiman Health Policy Institute.
Radiologists show no radiation-related mortality risk
July 19, 2016 -- Radiologists who started practice after 1940 face no increased risk of mortality compared to other physicians who aren't exposed to radiation as part of their jobs, according to a large new study published July 19 in Radiology. The results are a credit to long-term efforts to reduce occupational radiation exposure, the researchers said.
