Self-compression boosts women's mammography compliance

September 21, 2018 -- Allowing women some measure of control over breast compression at mammography doesn't reduce image quality or increase radiation dose -- and it may, in fact, encourage them to return for needed breast imaging, according to a French study published online on 14 September in the European Journal of Cancer.

Drop ultrasound contrast agent warning, society says

September 20, 2018 -- The International Contrast Ultrasound Society (ICUS) has filed a petition with the U.S. Food and Drug Administration urging the agency to remove boxed warnings from ultrasound contrast agents. ICUS believes the warnings are obsolete in light of clinical experience and recently released data on the safety of the agents. Discuss

Countdown to Brexit: Impact on radiology

September 19, 2018 -- There are less than six months to go until the U.K. is due to leave the European Union, but is it any clearer about what Brexit will mean for medical imaging? Our market columnist Stephen Holloway looks into the crystal ball and offers some predictions about the rocky road ahead. Discuss

AI algorithm produces synthetic brain MR images

September 18, 2018 -- An artificial intelligence (AI) algorithm can produce synthetic brain MR images, solving a number of challenges in training AI algorithms, according to research presented on 16 September at the International Conference on Medical Image Computing and Computer Assisted Intervention in Granada, Spain. Discuss

Coronary CT angio makes giant leap in dose reduction

September 17, 2018 -- A large international survey of radiation dose has demonstrated a huge reduction of radiation exposure in coronary CT angiography over the last decade. The study has shown doctors have reduced radiation exposure while maintaining image quality. Discuss

Breast screening critics Gotzsche, Welch lose positions

September 17, 2018 -- Last week was a bad one for opponents of breast cancer screening. On Saturday, prominent screening opponent Dr. Peter Gøtzsche was booted from the governing board of the Cochrane just days after screening skeptic Dr. H. Gilbert Welch resigned from Dartmouth College over plagiarism allegations. Discuss

DBT: Longer reading time, lower breast cancer recall rate

September 14, 2018 -- Interim analysis of a randomized controlled trial on digital breast tomosynthesis (DBT) showed the modality took longer to read than digital mammography but had significantly lower recall rates. The Norwegian researchers also found no differences in radiation dose between the two techniques, thanks to the use of synthesized DBT images. Discuss

NHS: Scottish women not invited to final breast screening

September 14, 2018 -- The National Health Service (NHS) Scotland is contacting nearly 1,800 women following revelations that they did not receive invitations to their final round of breast screening. Discuss

Can an AI algorithm triage routine abdominal CT exams?

September 13, 2018 -- An artificial intelligence (AI) algorithm can be highly sensitive and specific for identifying acute findings on abdominal CT scans enabling radiologists to prioritize reading of those urgent exams, Swiss researchers reported in an article published online on 7 September in Investigative Radiology. Discuss

Study rejects mammography's role in reducing mortality

September 13, 2018 -- The findings of a new Danish-Norwegian study are reviving the claim that the recent drop in breast cancer mortality is not due to mammography screening but rather the result of improved treatment. The authors assert it's time to consider alternatives to mammography screening -- such as breast palpation by physicians. Discuss
