AI spots lung nodules on CT, with low false-positive rate
August 30, 2018 -- A group from Alabama has developed a deep-learning artificial intelligence (AI) algorithm capable of detecting lung nodules on CT scans while maintaining a low false-positive rate, according to an article published online August 22 in the Journal of the American Medical Informatics Association.  Discuss
CT screening program targets nuclear weapons workers
August 28, 2018 -- Should occupational hazards be considered when deciding whether individuals should receive CT lung cancer screening? Researchers from New York investigated that question by performing CT lung screening scans on a population of nuclear weapons workers, publishing the results August 23 in the American Journal of Public Health.  Discuss
Radiologist use of CCTA continues its upswing
August 28, 2018 -- The utilization rate of coronary CT angiography (CCTA) by radiologists has hit an all-time high since Medicare started covering the test in 2006 -- now surpassing the usage rate of CCTA by cardiologists by 20%, according to an article published online August 26 in the Journal of the American College of Radiology.  Discuss
CCTA biomarker may predict mortality from heart disease
August 28, 2018 -- The use of coronary CT angiography (CCTA) to measure fatty tissue around arteries could help predict the risk of mortality from heart disease, according to research published online on 28 August in the Lancet and being presented at the European Society of Cardiology congress in Munich.  Discuss
CT finds heart disease in patients with lung cancer
August 27, 2018 -- Assessing coronary artery disease on the CT scans of patients with lung cancer can help clinicians identify which patients require surgery for both the heart and lungs, according to research published online August 16 in the Thoracic and Cardiovascular Surgeon.  Discuss
Chest CT CAD software speeds up reporting time
August 27, 2018 -- Chest CT computer-aided detection (CAD) software integrated into a radiology report dictation application reduced radiologist reading times by up to 44% over conventional manual interpretations, according to research published online in Academic Radiology.  Discuss
SCOT-HEART: CCTA cuts risk of heart attack, death by 41%
August 25, 2018 -- Patients with chest pain who underwent coronary CT angiography (CCTA) with standard care had a markedly lower rate of myocardial infarction or death from coronary artery disease than those who only received standard care in a new study, published on August 25 in the New England Journal of Medicine.  Discuss
Lung cancer overdiagnosis varies widely on CT screening
August 17, 2018 -- The concept of overdiagnosis has bedeviled the mammography screening debate, and it's beginning to show up in CT lung cancer screening as well. A study published online August 13 in JAMA Internal Medicine found an overdiagnosis rate of 67% in a Danish lung screening program -- much higher than rates in other programs.  Discuss
5 risk factors help predict brain hemorrhage on CT
August 17, 2018 -- U.K. researchers have identified five factors -- including contrast leakage on CT scans -- that may indicate a higher risk of continued bleeding in the brain of stroke patients. Checking for these factors may help improve survival, according to an article published online on August 14 in Lancet Neurology.  Discuss
