AI can help distinguish lung nodules on CT scans
March 2, 2018 -- VIENNA - Artificial intelligence (AI) offers value in characterizing nodules on CT lung cancer screening exams, possibly reducing the number of benign cases that are unnecessarily worked or followed up, according to a pair of Thursday presentations at ECR 2018.  Discuss
Does colonoscopy top CTC for cancer screening?
March 2, 2018 -- Is colonoscopy or CT colonography (CTC) more cost-effective when screening for colorectal cancer? Dutch researchers get to the bottom of this question in a study published online February 27 in Radiology.  Discuss
Deep learning can detect intracranial calcifications on CT
March 2, 2018 -- VIENNA - A deep-learning algorithm can accurately detect and measure the volume of intracranial calcifications, potentially facilitating research that could lead to new treatments for intracranial atherosclerosis, according to findings presented on Thursday at ECR 2018.  Discuss
Size matters: Belgians scoop ECR 2018 prize for dose study
February 28, 2018 -- VIENNA - Body size has an influence on the dose conversion factors of a conventional chest posteroanterior examination for the organs in the field-of-view, except for the thyroid, according to an award-winning Belgian study being presented this week at ECR 2018.  Discuss
CCTA usage rate rises sharply, but still eclipsed by MPI
February 23, 2018 -- The use of coronary CT angiography (CCTA) to evaluate chest pain in the emergency department has grown exponentially, but clinicians are still using myocardial perfusion imaging (MPI) far more frequently, according to research published online February 15 in the American Journal of Roentgenology.  Discuss
Ultralow-dose CT slashes radiation dose for fractures
February 21, 2018 -- Just how low can CT radiation dose go? Researchers from New York City found that radiologists performed well when reading extremity trauma scans acquired with an ultralow-dose protocol with dose levels approaching those of x-ray, according to a study published in the Journal of Orthopaedic Trauma.  Discuss
FDA clears Viz.ai's stroke detection software
February 13, 2018 -- In a move that blazes a regulatory trail for developers of imaging artificial intelligence (AI) software, the U.S. Food and Drug Administration (FDA) has given its blessing to Viz.ai for Contact, an AI-based application that analyzes CT images and notifies providers that a patient might be having a stroke.  Discuss
French find no need for CT to rule out PE
February 13, 2018 -- French researchers found that a set of clinical criteria was just as accurate as a protocol that included CT pulmonary angiography for ruling out pulmonary embolism (PE) in the emergency department, according to an article published in the February 13 issue of the Journal of the American Medical Association.  Discuss
