DWI-MRI could help show gene expression in tumors December 23, 2016 -- Researchers from California have developed a way to use diffusion-weighted MR imaging (DWI-MRI) to noninvasively monitor gene expression in tumor cells in living tissue, according to a study published online December 23 in Nature Communications.
Vancouver lung cancer predictor works in NLST December 22, 2016 -- A Canadian model for predicting lung cancer risk based on nodule and patient characteristics distinguished benign from malignant lung nodules in patients in the National Lung Screening Trial (NLST), according to a study presented at RSNA 2016. A second study in the same session, however, found that radiologists slightly outperformed the model.
State tort reform reduces orders for x-rays December 22, 2016 -- Tort reforms that make it harder to sue physicians have a stronger effect on reducing x-ray orders than reforms that directly reduce payouts for physician errors, according to a new study published online December 21 in the Journal of the American College of Radiology.
Pediatric MRI safety needs to target youngest patients December 21, 2016 -- Pediatric patients younger than 6 years old are the most vulnerable when it comes to MRI safety issues, according to a study performed at Massachusetts General Hospital in Boston and presented at RSNA 2016. The findings have prompted a call for quality improvements when it comes to scanning kids.
Density notification letters leave women with questions December 21, 2016 -- Connecticut passed the first breast tissue density notification law seven years ago. Now 28 states have enacted similar legislation, mandating that women be informed if they have dense tissue. But even if women understand the content of notification letters, do they know what to do next? Not necessarily, according to a talk given at the RSNA 2016 meeting.
Iranians collect RSNA prize for eye research December 21, 2016 -- A team from Tehran, Iran, scooped a prestigious cum laude award from poster-hall judges at RSNA 2016 for its practical and timely work on what interventional radiologists need to know about retinoblastoma.
Deep learning helps spot CT exams with critical findings December 20, 2016 -- Deep-learning technology can be a useful tool for identifying cases that contain critical imaging findings, potentially expediting the interpretation of these exams and the communication of results, according to a presentation at the recent RSNA 2016 meeting in Chicago.
Is the 5-gauss line of your MRI scanner safely contained? December 20, 2016 -- The U.S. is currently experiencing an upsurge in sales of preowned MRI equipment. While this is beneficial for the imaging industry and the cost-conscious healthcare economy, it brings with it a number of challenges, namely how to safely install an MRI machine.
