CT lung screening cuts cancer mortality 51% in Japan
December 14, 2018 -- In a new large-scale trial of CT lung cancer screening, researchers are reporting that screening reduced the risk of lung cancer mortality by 51% compared with x-ray screening in a Japanese population that included low-risk individuals and nonsmokers. Their findings were published online December 12 in the Japanese Journal of Clinical Oncology.  Discuss
U.K. study underscores mammography's effectiveness
December 14, 2018 -- Breast cancer screening with digital mammography is effective at finding life-threatening cancers early without increasing recall rates, according to a study published December 11 in Radiology. The findings offer further evidence of the benefits of routine screening mammography.  Discuss
Mouse kidney MR image wins top honors
December 14, 2018 -- A diffusion-tensor MR image (DTI-MRI) of a mouse kidney described as "stunning" has been named the top image in the second annual "research in progress" photo competition held by BMC.  Discuss
Are better clinical results from DBT worth the cost?
December 14, 2018 -- The transition from digital mammography to digital breast tomosynthesis (DBT) for routine breast cancer screening has its benefits, such as lower recall rates and better cancer detection. But DBT also leads to higher healthcare costs, according to research presented at the recent RSNA 2018 meeting.  Discuss

Top 5 trends from RSNA 2018 in Chicago
December 13, 2018 -- Stop us if you've heard this before, but there was a dominant theme at this year's RSNA 2018 meeting in Chicago. And that theme, believe it or not, was artificial intelligence (AI). As at RSNA 2017, sessions on AI and the related topics of machine learning and deep learning dominated the halls of McCormick Place. However, the debate around AI has begun to shift in subtle ways.  Discuss
AR improves operative view for robotic thyroid surgery
December 13, 2018 -- Researchers from South Korea have developed a technique to enhance the safety of robotic thyroidectomy by overlaying augmented reality (AR) models, based on CT scans, directly onto patients during surgery, according to a study published in the December issue of Annals of Surgical Treatment and Research.  Discuss
RSNA 2018 Roundup: Philips Healthcare
December 13, 2018 -- An MRI scanner with sharply lower helium use, a new platform for the development of artificial intelligence algorithms, and a new ceiling-suspended digital radiography system were among the RSNA 2018 highlights in the booth of Philips Healthcare.

Dual-energy mammography plus AI could reduce biopsies
December 12, 2018 -- A new mammography technique that uses an artificial intelligence (AI) algorithm to map the biological tissue composition of tumors on dual-energy mammography images could help reduce unnecessary biopsies, according to a study published online December 11 in Radiology.  Discuss
Patients report long-term gadolinium presence in urine
December 12, 2018 -- New data are raising questions about how long it takes gadolinium to exit the body after MRI scans. Using urine samples, researchers from gadolinium patient advocacy group the Lighthouse Project found elevated levels of gadolinium in patients years after their scans -- levels that exceeded the reference levels of some labs.  Discuss
