Women benefit from ACA's ban on mammography co-pays

April 18, 2019 -- The Patient Protection and Affordable Care Act's (ACA) elimination of co-pays for screening mammography in 2010 has had a positive benefit for commercially insured women across a variety of racial and income groups, a study published online April 13 in the Journal of Women's Health has found.

AI can identify, classify prostate cancer on mpMRI

April 18, 2019 -- An artificial intelligence (AI) algorithm called FocalNet was able to identify prostate cancer on multiparametric MRI (mpMRI) nearly as well as experienced radiologists and also predicted the lesion's aggressiveness, according to research presented at the recent IEEE International Symposium on Biomedical Imaging in Venice, Italy.

MRE could measure brain function dramatically faster

April 17, 2019 -- U.S. and European researchers could be on the brink of advancing the measurements of brain function through a MRI brain scan to milliseconds with an MR elastography technique, according to a preclinical study published online April 17 in Science Advances. Discuss

Ga-68 PSMA-PET/CT for prostate wins Australian favor

April 17, 2019 -- When a prostate cancer staging exam is needed, clinicians at one Australian hospital are overwhelmingly choosing PET/CT with the radiopharmaceutical gallium-68 (Ga-68) prostate-specific membrane antigen (PSMA), according to a study published online April 11 in the Journal of Medical Imaging and Radiation Oncology.

AI can spot malpositioned catheters on pediatric x-rays

April 17, 2019 -- An artificial intelligence (AI) algorithm can automatically analyze pediatric x-rays to identify patients with incorrectly positioned catheters, potentially enabling these studies to be triaged for priority review by radiologists, according to research published online April 10 in the Journal of Digital Imaging. Discuss

Ultrasound in late pregnancy could reduce C-section rate

April 16, 2019 -- Performing ultrasound scans late in pregnancy helps women avoid undiagnosed breech presentation of their babies, translating to improved clinical outcomes, lower rates of emergency cesarean sections (C-sections), and perhaps even lower healthcare costs, according to a study published April 16 in PLOS Medicine. Discuss

The 5 things radiology needs to speed up AI use

April 16, 2019 -- What's needed to accelerate advances in artificial intelligence (AI) in radiology? New image reconstruction methods, automated image labeling and annotation techniques, pretrained model architectures, explainable AI, and imaging data aggregation are all needed, according to a special report published April 16 in Radiology. Discuss

Elastography can help characterize breast tumors

April 16, 2019 -- Breast elastography is an overlooked tool for evaluating breast cancer, especially since it shows promise for helping radiologists distinguish between benign and malignant lesions, according to a presentation delivered at the American Institute for Ultrasound in Medicine (AIUM) meeting in Orlando, FL. Discuss

CTC offers added value to colon cancer screening

April 16, 2019 -- CT colonography (CTC) nearly matched the predictive accuracy of colonoscopy for colorectal cancer screening, while also allowing for risk stratification by providing detailed insight into the nature of colorectal findings in a new study, published online April 11 in the American Journal of Roentgenology. Discuss

3D-bioprinted model mimics real human heart properties

April 16, 2019 -- Researchers from Israel have created a 3D-printed model that captures the immunological, biochemical, cellular, and anatomical properties of a real human heart, according to an article published online April 15 in Advanced Science. Discuss
