Virtual reality goggles can make users queasy
February 1, 2016 -- In a stroke of virtual irony, people with the best 3D vision are the most likely to experience motion sickness when viewing virtual reality displays, according to new research in the journal Entertainment Computing.
Algorithm corrects contrast enhancement artifacts in dual-source CTC
January 25, 2016 -- A new postprocessing technique for dual-source CT colonography (CTC) corrects for artifacts that mimic contrast enhancement created by fecal tagging materials. The algorithm boosts sensitivity and reduces false-positive detections significantly.
Study finds differences in how breast density is measured
January 20, 2016 -- A study of nearly 2,000 breast cancer patients who underwent screening mammography found significant differences between three different methods of measuring breast density -- though breast cancer risk predictions were similar among the techniques, concludes a report in Radiology.
Cardboard VR viewer helps docs see infant's heart defects
January 18, 2016 -- Florida doctors were able to plan a successful surgical procedure on an infant with severe heart defects, using cardiac CT images visualized with a virtual reality (VR) image viewer made from cardboard.
Motion correction improves CT lung tumor assessment
December 17, 2015 -- Perfusion CT is emerging as a useful way to assess the treatment of lung cancer patients, but respiratory motion can cause problems with images. Fortunately, researchers from California and Pennsylvania have discovered a motion correction algorithm that can help.
Automated CAC fares well in CT lung screening scans
December 7, 2015 -- CHICAGO - Automated coronary artery calcium (CAC) scoring is robust and accurate when applied to lung cancer screening exams -- even when applied to a different population than the algorithm was designed for, according to results presented on Thursday at the 2015 RSNA meeting.
CT, 3D printing help team separate conjoined girls
December 3, 2015 -- CHICAGO - In an amazing 26-hour operation, a multidisciplinary team used CT scans and a 3D-printed model of the organs of conjoined twins to help perform a successful separation. Details of the effort were presented at this week's RSNA conference.
Gaming console might help produce better x-rays
December 1, 2015 -- CHICAGO - The gaming console your children use to destroy alien villains on distant fictional planets may help radiologists improve the quality of x-rays, researchers reported at the annual RSNA conference.
3D images aid selection of heart transplant donors
November 19, 2015 -- Researchers in Arizona are building a virtual library of 3D hearts in a bid to improve the matching process between heart transplant donors and recipients, and to make the best use of the perpetually tight supply of donor organs.
Forget Watson -- it's the pigeons you should worry about
November 18, 2015 -- If you think artificial intelligence could replace radiologists someday, there may be a new menace: It turns out that pigeons can distinguish benign from malignant tissue and identify certain cancer features with similar accuracy as their human counterparts, according to a new study published in PLOS One.
