How accurate are DCIS predictions from radiologists?
March 30, 2017 -- Radiologists can predict the presence of invasive cancer with fairly high accuracy, but their accuracy dips when it comes to predicting ductal carcinoma in situ (DCIS), according to a study published in the April issue of the American Journal of Roentgenology.
#MyRadGirlfriend No. 32: Customer-focused imaging?
March 30, 2017 -- There's no doubt that radiology is changing, but not all of those changes are for the better. Andy finds that some of the recent changes in her department are a bit hard to swallow in the next installment of #MyRadGirlfriend.
AIUM: Is MRI really needed after MSK ultrasound?
March 29, 2017 -- ORLANDO, FL - MRI exams performed after an initial musculoskeletal (MSK) ultrasound study are nearly always concordant with ultrasound results and rarely change clinical management, according to a Tuesday presentation at the American Institute of Ultrasound in Medicine (AIUM) conference.
AIUM: Machine learning may aid breast ultrasound reads
March 28, 2017 -- ORLANDO, FL - After analyzing quantitative information from breast ultrasound exams, machine-learning technology can achieve high sensitivity and specificity for breast cancer, according to research presented on Monday at the American Institute of Ultrasound in Medicine (AIUM) meeting.
DBT improves sensitivity in less-experienced readers
March 28, 2017 -- Adding digital breast tomosynthesis (DBT) to 2D screening mammography has a different effect based on who's reading the images, according to a new study published online on March 13 in Radiology. It improves specificity for all readers, but sensitivity improvements are reserved for more junior radiologists.
AIUM: NIH prepares for potential re-emergence of Zika virus
March 27, 2017 -- ORLANDO, FL - Much has been learned in the past year about the Zika virus and the damage it causes, but the big question now is whether a new outbreak will flare up in 2017, a key U.S. government official told attendees on Sunday at the American Institute of Ultrasound in Medicine (AIUM) annual meeting.
fMRI scans may help choose depression treatment strategy
March 27, 2017 -- Researchers using functional MRI (fMRI) have found specific patterns of brain activity that may help determine whether behavioral therapy or antidepressant medication is better for patients with depression, according to research published online March 24 in the American Journal of Psychiatry.
ACA repeal effort falls short as GOP can't muster votes
March 24, 2017 -- Republicans have shelved legislation that would have repealed the Affordable Care Act (ACA) -- known colloquially as Obamacare. In a March 24 press conference, President Donald Trump acknowledged the failure of the repeal effort and said his administration will now move on to other priorities, such as tax reform.
3D printers help build a better cranial nerve
March 24, 2017 -- Researchers have created a high-resolution model of a 3D-printed brain and skull base from CT and MR images that details the cranial nerves in ways that outperform standard diagnostic images. The complex neuroanatomy of the nerves can be better understood and depicted by the use of highly customizable 3D-printed models, according to a report in the Journal of Digital Imaging.
Can deep-learning CAD outperform mammographers?
March 23, 2017 -- Can computer-aided detection (CAD) software developed with deep-learning technology perform better than mammographers? Yes it can, at least for the task of differentiating between benign and malignant calcifications, according to a team of researchers from California.
