CCTA radiomics yields insights into nature of coronary artery disease
February 16, 2021 -- Radiomics analysis of coronary CT angiography (CCTA) exams found that cardiovascular risk factors such as cocaine use and HIV affect development of atherosclerosis in different ways, according to a February 16 study in Radiology.  Discuss
3D-printed surgical guides enhance breast conservation therapy
February 12, 2021 -- 3D-printed surgical guides can be useful in breast conservation surgery performed on breast cancer patients after neoadjuvant systemic therapy, according to research published online February 9 in Scientific Reports.  Discuss
AI can predict need for steroid treatments in COVID-19 patients
February 11, 2021 -- Deep learning-based analysis of chest CT exams can predict if COVID-19 patients will need to be treated with steroids, as well as monitor their progression, according to a recent webinar presentation.  Discuss
Deep-learning algorithm can detect, quantify aortic valve calcium
February 9, 2021 -- Researchers from South Korea reported that their artificial intelligence (AI) model was highly accurate for automatically detecting and quantifying aortic valve calcium on cardiac CT, even outperforming radiologist assessments in severe cases.  Discuss
New COVID-19 AI models offer promising results
February 8, 2021 -- Deep-learning models that have been trained on datasets from multiple institutions around the world yield promising and generalizable results for identifying COVID-19 pneumonia on chest CT exams, as well as in predicting adverse patient outcomes.  Discuss
MRI-targeted biopsy shows value in prostate cancer
February 5, 2021 -- Multiparametric MRI-targeted biopsy for clinically significant prostate cancer can yield detection rates similar to systematic transrectal ultrasound-guided biopsy, while potentially enabling over one-third of prostate biopsies to be avoided, according to research published online February 4 in JAMA Oncology.  Discuss
AI for image interpretation: Friend or foe to radiologists?
February 4, 2021 -- Will using artificial intelligence (AI) for image interpretation tasks help radiologists enhance their value or will it eventually lead to fewer radiologist jobs? Point/counterpoint articles published online February 3 in the American Journal of Roentgenology shared two potential visions for radiology's future.  Discuss
AI predicts cardiovascular risk on routine chest CT
February 3, 2021 -- An artificial intelligence (AI) algorithm was able to predict patients' risk for future cardiovascular events by quantifying their coronary artery calcium on routine chest CT exams, according to research published online January 29 in Nature Communications.  Discuss
Study finds racial disparities in pediatric ED imaging
January 29, 2021 -- Non-Hispanic Black and Hispanic children are significantly less likely to receive a diagnostic imaging study when visiting an emergency department (ED) than non-Hispanic white patients, according to analysis of over 13 million pediatric ED visits published online January 29 in JAMA Network Open.  Discuss
Mirai AI model upgrades breast cancer risk assessment
January 28, 2021 -- An artificial intelligence (AI) algorithm called Mirai can outperform other risk-assessment models for predicting future risk of breast cancer from a mammogram, potentially enabling earlier identification of high-risk women, according to research published online January 27 in Science Translational Medicine.  Discuss
