PET/MRI boosts cancer detection
September 17, 2020 -- PET/MRI helps clinicians stage cancer treatment as well as PET/CT -- and finds more than 25% additional cancers, according to a study published in the Journal of Nuclear Medicine. It also reduces overall radiation exposure.  Discuss
French survey logs COVID-19's impact on radiologists
September 17, 2020 -- The COVID-19 pandemic is exacting a heavy psychological toll on radiologists, with insomnia being one of the most commonly reported problems, according to a French survey of over 1,500 imaging physicians.  Discuss
CT radiomics predicts esophageal cancer outcomes
September 11, 2020 -- Machine-learning models that assess both peritumoral and intratumoral radiomics features on pretreatment CT images can yield a promising level of performance for predicting treatment outcomes in patients with esophageal squamous cell carcinoma, according to research published online September 10 in JAMA Network Open.  Discuss
Are clinicians ordering CT lung screening too often?
September 10, 2020 -- Referring providers are ordering CT lung cancer screening exams for individuals who don't meet established clinical guidelines for the tests, according to a study published September 6 in the Journal of the American College of Radiology.  Discuss
CT shows COVID-19 causes lingering lung damage
September 9, 2020 -- Six-week follow-up CT exams of patients with COVID-19 show lingering damage to lung tissue in 88% of patients who were hospitalized, according to a presentation delivered September 7 at the virtual European Respiratory Society International Congress.  Discuss

CT scan helps solve another Cuban mystery case
September 8, 2020 -- CT helped solve the case of a tourist who developed neurological impairment after a trip to Cuba, according to a September 8 report published in JAMA Neurology. The tourist's symptoms were remarkably similar to those of U.S. and Canadian diplomats who were suspected of being victims of a "sonic weapon" in 2016.  Discuss
AI can spot smokers at high risk of cancer on x-rays
September 4, 2020 -- By analyzing chest radiographs and a patient's electronic medical record (EMR), a deep-learning algorithm was able to identify more high-risk smokers who could benefit from CT lung cancer screening than current Medicare eligibility criteria, according to research published September 1 in the Annals of Internal Medicine.  Discuss
Chest CT effective for COVID-19 diagnosis
September 2, 2020 -- French researchers have found that chest CT is an effective tool for initial diagnosis of COVID-19, according to a study published September 1 in Radiology. The results challenge current guidelines that have discouraged initial use of CT for COVID-19.  Discuss
Virtual imaging trials could optimize COVID-19 imaging
September 2, 2020 -- Researchers have created computerized models of lung abnormalities on CT scans of patients with COVID-19, according to an August 28 study in the American Journal of Roentgenology. The virtual imaging models can be used like computerized phantoms for research into the use of imaging to detect and monitor the disease.  Discuss
