Study: FDG-PET reigns supreme for assessing Alzheimer's
August 9, 2019 -- FDG-PET is superior to amyloid PET imaging with the radiopharmaceutical florbetapir for assessing cognitive decline in patients with Alzheimer's disease or mild cognitive impairment, according to research published in the August issue of the Journal of Alzheimer's Disease.  Discuss
AI may help cut back on overutilization of CT for PE
August 8, 2019 -- An artificial intelligence (AI) algorithm can predict -- from electronic medical record data -- if a patient is likely to have a pulmonary embolism (PE) prior to receiving CT pulmonary angiography, potentially avoiding unnecessary scans, according to research published online August 7 in JAMA Network Open.  Discuss
AI-based model enhances diagnosis of brain MRI exams
August 7, 2019 -- An artificial intelligence (AI)-based model that mimics a radiologist's image interpretation process can provide automated diagnosis of brain MRI exams at a level comparable to an academic neuroradiologist, according to researchers from the Hospital of the University of Pennsylvania in Philadelphia.  Discuss
AI accurately estimates bone age on 3D hand MRI
August 5, 2019 -- An artificial intelligence (AI) algorithm can estimate bone age in children and adolescents from analysis of a 3D hand MRI exam with a very high level of accuracy, according to research published online July 31 in Medical Image Analysis. What's more, it can also perform well on wrist radiographs.  Discuss
AI enhances radiologist performance for DBT
July 30, 2019 -- General radiologists and breast imaging subspecialists can both benefit significantly from reading digital breast tomosynthesis (DBT) studies concurrently with artificial intelligence (AI) software, reported researchers from the University of Pennsylvania and computer-aided detection firm iCAD.  Discuss
AI algorithm helps prioritize urinary stones on CT
July 26, 2019 -- An artificial intelligence (AI) model was highly accurate for detecting urinary tract stones on unenhanced CT studies, enabling priority review of these cases by radiologists and referring physicians in a new study, published online July 24 in Radiology: Artificial Intelligence.  Discuss
AI can glean cancer outcomes from radiology reports
July 25, 2019 -- Artificial intelligence (AI) algorithms can accurately identify the presence of cancer and changes in disease burden described on radiology reports, potentially paving the way for personalized medicine on a large-scale basis, according to research published online July 25 in JAMA Oncology.  Discuss
CAD research often neglects implementation issues
July 23, 2019 -- Research published in the literature on mammography computer-aided detection (CAD) software has focused largely on diagnostic accuracy, with very few studies addressing how radiologists use and perceive the technology, according to an article published online July 18 in JMIR Medical Informatics.  Discuss
AI reveals prognostic information in chest x-rays
July 22, 2019 -- An artificial intelligence (AI) algorithm can identify patients who are at higher risk of long-term mortality by analyzing their chest radiographs, potentially enabling early prevention and lifestyle interventions, according to research published online July 19 in JAMA Network Open.  Discuss
AI can diagnose Alzheimer's from imaging, test scores
July 18, 2019 -- An artificial intelligence (AI) model that simulates a clinician's diagnostic process by analyzing both neuroimaging results and clinical cognitive impairment test scores can yield excellent performance for diagnosing Alzheimer's disease, according to research published online July 16 in Neurocomputing.  Discuss
