AI can quantify hematoma in hemorrhagic stroke patients
November 13, 2020 -- An artificial intelligence (AI) algorithm was able to segment and quantify hematoma on noncontrast whole-head CT scans in acute hemorrhagic stroke patients at an accuracy level comparable to that of an expert, according to research published online November 9 in Scientific Reports.  Discuss
Large study confirms value of CT lung cancer screening
November 12, 2020 -- CT lung cancer screening reduces the risk of death from lung cancer, according to a new meta-analysis that combines data from all randomized controlled trials performed so far. In fact, CT lung screening compares favorably with breast screening, researchers reported in the November edition of the Annals of Family Medicine.  Discuss
CT radiation doses for COVID-19 patients vary widely
November 11, 2020 -- Lack of guidance for how best to use CT with COVID-19 has led to significant variations in standard measurements of CT radiation dose, according to a study published November 10 in Radiology.  Discuss
Medical imaging boosts men's testicular cancer risk
November 11, 2020 -- Early exposures to medical imaging can increase men's risk of developing testicular cancer by almost 60%, according to a study published November 11 in PLOS One. The findings highlight the need for shielding for men and boys during imaging exams.  Discuss
Imaging saves teen with oral surgery-linked 'forgotten disease'
November 10, 2020 -- Imaging and early antibiotic intervention saved the life of an 18-year-old man in Kansas who was diagnosed with Lemierre syndrome, or the "forgotten disease," after wisdom teeth extraction, according to a case report published on October 20 in the Cureus Journal of Medical Science.  Discuss
Cancer delays: Counting COVID-19's hidden costs
November 9, 2020 -- A patient whose cancer treatment is delayed by even one month can face a mortality risk of up to 13% higher, a Canadian and U.K. study has found. The investigation, published online by BMJ on 4 November, was triggered by concerns about delays to cancer diagnosis and therapy during the pandemic.  Discuss
CT lung screening scans also work for bone density
November 6, 2020 -- CT scans acquired for lung cancer screening can serve double-duty by providing the data needed to also perform bone density analysis, according to a new study from China published online November 4 in the Journal of Bone and Mineral Research.  Discuss
CT lung screening program falls short in China
November 3, 2020 -- A large study from a real-world CT lung cancer screening program in China failed to find a benefit to screening high-risk individuals, according to a study published in JAMA Network Open online November 3. But the results may have been affected by compliance and how the screening protocol was set up.  Discuss
AI model's sensitivity for aneurysms comes at a price
November 3, 2020 -- An artificial intelligence (AI) algorithm helped improve the detection of cerebral aneurysms on CT angiography scans, but at the cost of a high false-positive rate in a study conducted in China and reported online November 3 in Radiology.  Discuss
Free app helps radiologists recognize COVID-19 cases
November 3, 2020 -- A free app designed to train medical imaging professionals in COVID-19 case recognition is making progress. While other apps exist, users of the BerlinCaseViewer app have access to all the CT slices they would have on their workstations in normal clinical practice, the developers say.  Discuss
