Could self-rated health improve CT CAC scoring?
February 19, 2019 -- Combining self-rated health assessments with CT coronary artery calcium (CAC) scoring enhanced the test's ability to predict a person's risk of adverse cardiac events -- almost matching the accuracy of traditional risk estimation, according to an article published online February 15 in JAMA Network Open.  Discuss
TexLab AI algorithm predicts ovarian cancer survival
February 15, 2019 -- By analyzing tumor characteristics such as structure, shape, and size, an artificial intelligence (AI) algorithm called TexLab 2.0 is able to predict which patients with ovarian cancer have the best prognosis. The prediction can then be used to direct patient therapy, according to an article published online February 15 in Nature Communications.  Discuss
Lung cancer imaging on the upswing in China
February 15, 2019 -- CT appears to be taking over for x-ray as a tool for the diagnosis of lung cancer in China, where imaging utilization rates have generally trended upward over the past decade -- most notably in underdeveloped regions of the country, according to an article published online February 8 in Thoracic Cancer.  Discuss
Heart societies endorse CT CAC for risk assessment
February 12, 2019 -- The American Heart Association and the American College of Cardiology have reaffirmed their support for the use of CT coronary artery calcium (CAC) testing to estimate heart disease risk, according to an article published online February 11 in the Annals of Internal Medicine.  Discuss
Some thoughts on Dr. Phillip Berman and CT lung screening
February 8, 2019 -- Radiologist and imaging entrepreneur Dr. Phillip Berman died of lung cancer 10 years ago today -- and 20 years ago this month he founded AuntMinnie.com. In this article, his friend Sheila Ross looks back and wonders what Phil would think about the progress that has -- and hasn't -- been made with CT lung cancer screening.  Discuss

February 8, 2019 -- The combination of artificial intelligence (AI) and radiomics features on CT images can outperform current methods for preoperatively predicting lymph node metastasis from gastric cancer, according to research published online February 4 in the Journal of the American College of Radiology.  Discuss
Academic pediatric facilities have lower CT radiation dose
February 7, 2019 -- Academic pediatric facilities used about half the radiation dose that other U.S. medical facilities used for pediatric CT scans of the chest, abdomen-pelvis, and brain -- with significantly less variation in dose, according to an article published online February 5 in Radiology.  Discuss
CT matches MRI for late-window stroke evaluation
February 6, 2019 -- Stroke patients who underwent endovascular therapy had similar improvement after their treatment regardless of the type of perfusion imaging -- CT or MRI -- that clinicians used to confirm their eligibility for surgical procedures, according to an article published online January 28 in JAMA Neurology.  Discuss
Radiologists can help detect signs of domestic violence
February 5, 2019 -- By recognizing signs of trauma on imaging exams, radiologists can help identify cases of domestic violence between intimate partners, according to a study published February 5 in Radiology. Researchers identified imaging and demographic factors associated with a greater likelihood of abuse.  Discuss
Russian AI detects lung cancer on CT in 20 seconds
February 4, 2019 -- Researchers from Russia have developed an artificial intelligence (AI) program called Doctor AI-zimov that is capable of identifying and marking lung nodules -- some as small as 2 mm -- on CT scans in under 20 seconds.  Discuss
