Erik L. Ridley[email protected]UltrasoundAI bolsters specificity of screening breast ultrasoundA diagnostic model that incorporates artificial intelligence (AI)-based quantitative analysis can significantly decrease false-positive rates for masses detected on screening breast ultrasound exams, potentially helping to reduce unnecessary biopsies, according to a study published online January 11 in Scientific Reports.January 11, 2021BreastCan AI spot breast cancer years before radiologists?A deep-learning algorithm successfully detected breast cancer on screening mammography, in some cases as early as two years before it was diagnosed during conventional interpretation, according to research published online January 11 in Nature Medicine. The algorithm also performed well with digital breast tomosynthesis (DBT) exams.January 10, 2021Image ProcessingLung involvement portends COVID-19 mortality riskVolumetric analysis of lung consolidation on chest CT scans can be used to predict the risk of COVID-19 patients dying in the hospital and aid in management decisions, researchers from Michigan reported in a study published online January 6 in European Journal of Radiology Open.January 7, 2021Image ProcessingCT/ultrasound fusion enhances ovarian biopsiesA method that combines CT radiomics and real-time CT/ultrasound image fusion can yield more accurate and efficient tissue biopsies in ovarian cancer patients and may, in the future, even facilitate "virtual" biopsies, according to research published online December 14 in European Radiology.January 7, 2021CTAI predicts metastasis in gastric cancer patientsAn artificial intelligence (AI) algorithm can predict the presence of occult peritoneal metastasis in gastric cancer patients based on preoperative CT scans, potentially helping in treatment decision-making and avoiding unnecessary surgeries, according to research published online January 5 in JAMA Network Open.January 6, 2021PACS/VNAOptum bids to buy Change Healthcare in $13B dealUnitedHealth Group's Optum health services company has signed an agreement to acquire healthcare information systems and enterprise imaging vendor Change Healthcare in a deal valued at over $13 billion.January 5, 2021Image-Guided SurgeryUltralow-dose CT doesn't hurt value of 3D modelsCT images acquired at ultralow radiation doses can be used to produce 3D-printed models of wrist fractures that are just as useful as 3D models generated from standard-dose CT exams, according to research published online December 23 in the European Journal of Radiology.January 4, 2021Image-Guided Surgery3D printing, AR can enhance thoracoscopic surgeryThe combination of 3D printing and augmented reality (AR) technologies can yield better outcomes for planning and guiding thoracoscopic surgeries than relying on virtual 3D lung models displayed on a monitor in the operating room, according to research published online December 1 in the Annals of Thoracic Surgery.December 13, 2020Digital X-RayAI improves lung cancer detection on x-raysAn artificial intelligence (AI) algorithm can catch lung cancers that were initially missed by radiologists on chest radiographs and improve radiologist performance when used as a second reader, according to research published online December 10 in Radiology: Cardiothoracic Imaging.December 10, 2020Advanced VisualizationAI body analysis finds lung cancer survival risk factorsAn artificial intelligence (AI) algorithm was able to quickly analyze body composition metrics on abdominal/pelvic CT exams, yielding better prognostic information for survival in lung cancer patients than a patient's body mass index, according to research presented at the virtual RSNA 2020 meeting.December 10, 2020Previous PagePage 48 of 389Next PageTop StoriesAIU.S. FDA may need to clarify SaMD validation standardsIn a video interview, a Dana-Farber Cancer Institute expert describes what the "rigor spectrum" is in validation study designs.Molecular ImagingPSMA-PET/CT may replace NaF-PET/CT in advanced prostate cancerWomens ImagingPreop breast MRI improves surgical planning, but use disparities remainWomens ImagingFIGO classification from MRI leads to moderate agreement among radsSponsor ContentRegister Now: Breaking Barriers in Breast Imaging Webinar
