Iterative Reconstruction in CT Evolves for Lower Dose, Increased Clarity
Radiologists have been struggling to balance image noise with radiation dose in computed tomography (CT) scans for decades. But the competition just went up a notch (or perhaps many notches) with the recent FDA approval of GE Healthcare’s Model Based Image Reconstruction (MBIR) technology, Veo. While MBIR is the most advanced of the iterative reconstruction technologies, top manufacturers offer their own software answers to the noise versus dose argument.

 

CT Lung Screening Beats X-Ray — Now What?
Heavy smokers screened for lung cancer with low-dose helical CT scans had a 20 percent lower mortality risk than those screened with standard X-ray, according to a large scale study recently published in the New England Journal of Medicine. So should the lung cancer screening policy change?

 

Podcast: A Conversation about Lowering Dose
Diagnostic Imaging spoke with Dr. Johnsey Leef III, a radiologist with Charleston Area Medical Center in Charleston, WV, about how the industry is responding to the call for lower dose imaging and what his department is doing to address the issue.

 

Smaller Hospitals Reach CT Dose Reduction Through Education, Collaboration
By changing protocols for CT angiographic imaging, Gundersen Lutheran Health System, a physician-led, La Crosse, Wis.-based health system serving 19 counties, endeavored to reduce dose exposure after purchasing a dual-source CT system in 2006. The result of their program: a 29 percent drop in dose exposure.
