Canada-U.S. duo wins RSNA pneumonia AI challenge

November 16, 2018 -- An artificial intelligence (AI) algorithm written by a Canadian radiologist and a U.S. medical student was awarded first place in the RSNA Pneumonia Detection Challenge, a competition sponsored by the RSNA to foster the development of AI algorithms. Discuss

CT lung screening can catch recurring head, neck cancer

November 16, 2018 -- CT lung screening may have added value in cancer detection beyond the chest, say researchers from New York. CT screening could replace routine CT surveillance for detecting the recurrence of head and neck squamous cell carcinoma, according to findings published in the November issue of Oral Oncology.

Breast density advocate Cappello dies

November 16, 2018 -- Breast density advocate Nancy Cappello, PhD, died on November 15 due to complications related to a late-occurring side effect of breast cancer treatment. Cappello was instrumental in passing the first state breast density notification law and in raising awareness of the relationship between breast tissue density and cancer risk. Discuss

Can 7-tesla MRI make the transition to clinical prime time?

November 15, 2018 -- Is 7-tesla MRI ready to stake its claim in the radiology department? Currently, three institutions in the U.S. have begun using 7-tesla magnets for clinical applications, but mostly for neurological and musculoskeletal conditions. The challenge now is showing how much more 7-tesla MRI can contribute to patient care. Discuss

3D-printed lungs improve patient understanding of surgery

November 15, 2018 -- Using transparent, flexible 3D-printed models of the lung helped physicians improve patients' understanding of lung cancer surgery -- including its harms and benefits -- during informed consent consultations, according to an article recently published online in Seminars in Thoracic and Cardiovascular Surgery.

Artificial intelligence for MRI distinguishes uterine cancer from fibroids

November 15, 2018 -- A machine-learning algorithm for MRI helped clinicians differentiate uterine sarcomas from leiomyomas, according to a study published online November 12 in the European Journal of Radiology. The algorithm could help women avoid unnecessary surgery, concluded the researchers from Iran. Discuss

MRI depicts brain changes in self-injuring teen girls

November 15, 2018 -- MR images have shown that teenage girls who are prone to injuring themselves have reduced brain volume in two regions. The results suggest the root of the self-harming actions is also biological, rather than solely behavioral, according to a study published online November 5 in Development and Psychopathology.

Roadie winners point to hottest abstracts at RSNA 2018

November 14, 2018 -- What abstracts will generate the most interest at RSNA 2018? If the winners of our Roadie awards are any indication, hot topics will range from gadolinium retention in MRI to cinematic rendering in advanced visualization -- with artificial intelligence appearing poised to steal the show once again. Discuss

Are patients fleeing high costs of hospital-based imaging?

November 14, 2018 -- Patients with high-deductible health plans are shopping around before they select an imaging provider -- and many may flee the higher costs of hospital-based departments in favor of independent facilities, according to an article published online November 9 in the Journal of the American College of Radiology. Discuss

Are medical students avoiding radiology because of AI?

November 13, 2018 -- Are some medical students choosing not to pursue radiology as their specialty due to concerns over the potential effects of artificial intelligence (AI)? The answer appears to be yes, according to results from a survey of Canadian medical students published online November 11 in Academic Radiology. Discuss
