Erik L. Ridley[email protected]Image 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, 2020PACS/VNASecurity advisories issued for GE imaging systemsA security vulnerability found in more than 100 imaging systems from GE Healthcare could enable a cyberattacker to access or modify patient data, according to GE, security firm CyberMDX, and the U.S. Department of Homeland Security's Industrial Control Systems Cyber Emergency Response Team.December 7, 2020Advanced VisualizationMRI radiomics predicts axillary lymph node metastasisIn patients with early-stage breast cancer, "signatures" derived from MRI radiomics and patient clinical risk characteristics can be utilized to preoperatively predict axillary lymph node metastasis as well as disease-free survival, according to research published online December 8 in JAMA Network Open.December 7, 2020Previous PagePage 52 of 393Next PageTop StoriesHomeLLMs mostly avoid unnecessary care in Choosing Wisely testsLLMs recommended potentially unnecessary care in about 5% of responses, with many being thyroid ultrasound tests.Nuclear MedicineEANM: Thomas Hope on what’s next in FAP-targeted theranosticsCardiac ImagingMRI shows no ties between COVID, future heart inflammationMolecular ImagingEANM: Next-generation PET scanner cuts imaging time to one minuteAugmented/Virtual RealityVR boosts accuracy, confidence for evaluating abdominal neuroblastoma
