MRI Study Reveals Increased Brain Changes in Postmenopausal Women
July 1st 2022Emerging research with brain magnetic resonance imaging (MRI) scans shows that postmenopausal women have higher amounts of white matter hyperintensities that may lead to elevated risks for cognitive dysfunction and stroke.
Philips Adds Proteomic Nodule Risk Assessment to Lung Cancer Orchestrator System
June 30th 2022The addition of Biodesix’s Nodify Lung nodule risk assessment tool to Philips’ lung cancer patient management system may enhance diagnostic efficiency and facilitate improved management of high-risk patients.
Colorectal Cancer Screening: Could a Lower Age Threshold Reveal Greater Screening Disparities?
June 30th 2022In a large study looking at the use of colorectal cancer screening techniques (including computed tomography (CT) colonography) between 2000 and 2018, researchers found that the 50 to 54 age group had the lowest increases in screening and a significantly higher chasm of racial and socioeconomic disparities in comparison to other age groups.
New Study Shows Link Between COVID-19 and Elevated Risks for Neurological Disorders
June 25th 2022Emerging research showed that patients with COVID-19 had 3.5 times the risk for developing Alzheimer’s disease and 2.6 times the risk for Parkinson’s disease in comparison to those who did not have COVID-19.
Could an MRI-Based Machine Learning Model Facilitate Enhanced Detection of Alzheimer's Disease?
June 22nd 2022New research suggests that an emerging predictive biomarker, derived from a combination of magnetic resonance imaging (MRI) brain scans and a machine learning algorithm, has significantly greater accuracy than previously established measurements for diagnosing Alzheimer’s disease.
Essential Questions for Assessing Artificial Intelligence Vendors in Radiology
June 21st 2022In a recent video interview, abdominal radiologist Sonia Gupta, MD discussed key principles in assessing potential alliances with artificial intelligence (AI) vendors and the potential of AI to alleviate the time-consuming, administrative aspects of patient care.
Study Finds Key Benefits and Low Use of Pre-Op MRI for Patients Having Surgery for Prostate Cancer
June 17th 2022Despite increased use of preoperative magnetic resonance imaging (MRI) in recent years for patients undergoing surgery for prostate cancer, a study found that over 70 percent of a large Medicare population with prostate cancer did not have a preoperative MRI scan as of 2015.
AI Software Facilitates 22.1 Percent Reduction in Chest CT Review Time
June 17th 2022Noting that an AI software platform could save radiologists up to an hour a day in interpreting chest computed tomography (CT) scans, the authors of a prospective study found shorter mean interpretation times with non-contrast and contrast-enhanced CT as well as positive CT scans with and without significant new findings.
Is Whole Body Imaging Warranted for Thrombocytopenia Caused by a COVID-19 Vaccine?
June 14th 2022In what may be the largest study to date to examine the use of whole-body imaging to assess multisystem thrombosis in patients with COVID-19 vaccine-induced immune thrombotic thrombocytopenia, researchers found multiple sites of thrombosis in 83 percent of patients who had additional CT, MRI and/or ultrasound imaging beyond the area of their primary complaint.
Siemens Healthineers Get FDA Nod for New SPECT/CT Scanner
June 12th 2022The newly FDA-cleared Symbia Pro.specta SPECT/CT Scanner, which reportedly offers a variety of enhanced capabilities including low-dose CT up to 64 slices and intuitive workflow guides, was launched at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2022 Annual Meeting.

Study Suggests the COVID-19 Pandemic Led to Millions of Decreased Cancer Screenings
June 6th 2022A new survey study from the American Cancer Society shows a 4.47 million decrease in cervical cancer screenings and a 2.13 million decrease in breast cancer screenings in the United States between 2018 and 2020.
Lessons Learned from the Iodinated Contrast Media Shortage: A Neuroradiologist's Perspective
June 3rd 2022In a recent video interview on the current iodinated contrast media shortage, neuroradiologist Sean Bryant, MD discussed imaging alternatives, emphasized communication with referring physicians on optimal studies, and discussed the ongoing need to prevent “protocol creep” with timely updates of imaging protocols.
Can Diffusion-Weighted MRI Have an Impact in Detecting Recurrent Pancreatic Cancer?
May 29th 2022For post-op monitoring of patients who had pancreatic ductal adenocarcinoma (PDAC) resection, a new study showed that diffusion-weighted magnetic resonance imaging (MRI) had enhanced sensitivity for detecting recurrent tumors in comparison to conventional MRI.
