October 26, 2020 -- Using proton therapy to treat lung cancer patients may help reduce the risk of radiation-induced heart diseases, according to research to be presented October 25 at the American Society for Radiation Oncology 2020 virtual meeting.  Discuss
CT volume yet to rebound to pre-COVID-19 levels
October 26, 2020 -- The volume of CT studies performed in the U.S. has recovered since the early days of the COVID-19 pandemic. But as of the end of September, it was still far below pre-pandemic expectations, according to registry study data published in the Journal of the American College of Radiology.  Discuss
Radiomics can aid management of lung cancer patients
October 26, 2020 -- Researchers from the H. Lee Moffitt Cancer Center and Research Institute in Tampa, FL, have reported that CT radiomics features can help predict tumor behavior in screening-detected lung cancer. They've also found that PET/CT radiomics shows promise for guiding non-small cell lung cancer treatment decisions.  Discuss
Ultrasound pinpoints patients missed by COVID-19 tests
October 26, 2020 -- Physicians can use lung ultrasound scan results and clinical symptoms to identify patients with false-negative COVID-19 test results, according to the findings of an October 13 study in Annals of Emergency Medicine.  Discuss
Working group uses MRI to analyze brain trauma
October 23, 2020 -- A new working group has been established between international institutions to use MRI to investigate some of the most puzzling questions about traumatic brain injury. The group includes 170 researchers from 13 countries.  Discuss
Canon launches CT scanner with 90-cm bore at ASTRO 2020
October 23, 2020 -- Canon Medical Systems is taking advantage of this week's American Society for Radiation Oncology (ASTRO) virtual meeting to launch Aquilion Exceed LB, a CT scanner dedicated to radiation therapy planning. The new scanner sports a wide 90-cm bore and other features like artificial intelligence-based image reconstruction.  Discuss
Study supports more use of MRI in patients with implants
October 22, 2020 -- Many more patients with implanted devices like pacemakers could safely undergo MRI and reap clinical benefits of the modality than do so currently, according to a new registry study published in Radiology: Cardiothoracic Imaging online October 22.  Discuss
IMV: Radiation therapy volume stays steady despite COVID-19
October 22, 2020 -- Radiation therapy procedure volume has remained relatively stable throughout 2020, bucking a trend seen in diagnostic radiology, in which the COVID-19 pandemic has led to major drops in imaging exam volume. That's according to a new report on radiation oncology by market research firm IMV Medical Information Division.  Discuss
AI extracts more data from single-energy CT
October 22, 2020 -- An artificial intelligence (AI) algorithm was able to extract more data from conventional CT images, allowing single-energy CT to approach the performance of dual-energy CT without the additional radiation, according to a study published October 19 in the journal Patterns.  Discuss
Spectral CT boosts early COVID-19 assessment
October 22, 2020 -- Spectral CT is better at identifying early-stage COVID-19 disease than conventional CT, enabling better visualization of pulmonary lesions, according to a study published October 21 in the American Journal of Roentgenology.  Discuss
