CT CAC linked to cardiovascular mortality in young adults
July 22, 2019 -- Positive scores on CT coronary artery calcium (CAC) scans were strongly associated with an increased risk of heart disease and all-cause mortality in young adults in a new study, published online July 19 in JAMA Network Open. CT CAC testing could help direct these individuals to preventive therapy, researchers say. Read More
Could a metabolic test revamp CT lung cancer screening?
July 18, 2019 -- A low-cost metabolic test that uses MR spectroscopy to analyze blood and tissue samples may complement the early detection of lung cancer and help clinicians identify individuals who would benefit most from CT lung screening, according to an article published online July 16 in Scientific Reports.

Demographic factors limit access to CT lung screening
July 15, 2019 -- Smokers who are older, uninsured, undereducated, and live in a rural area are more likely to be located farther away from a CT lung cancer screening facility and thus have limited access to screening services, according to an article published online July 11 in the Journal of the American College of Radiology.

CT perfusion shows promising utility in cancer treatment
July 11, 2019 -- The CT perfusion scans of patients with pancreatic cancer revealed that those who responded well to chemoradiation therapy had higher blood flow measurements both before and after treatment than did patients who responded poorly in a new study, published online July 9 in Radiology.

CT lung screening's benefits persist over time
July 8, 2019 -- In an update to the National Lung Screening Trial, researchers from the U.S. are reporting a sustained reduction in cancer deaths from CT lung screening roughly 12 years after the initial screening exam. The findings were recently published online in the Journal of Thoracic Oncology. Read More
SIIM: AI exploits CT sinogram data to find lung nodules
June 28, 2019 -- DENVER - An artificial intelligence (AI) algorithm can accurately detect lung nodules on CT by analyzing both the reconstructed image and the raw sinogram data, according to research presented Thursday at the Society for Imaging Informatics in Medicine (SIIM) annual meeting.

CT lung screening criteria overlook racial differences
June 28, 2019 -- Current eligibility criteria for CT lung cancer screening from the U.S. Preventive Services Task Force do not account for racial differences -- leaving behind a large proportion of African American smokers who would benefit from the test, say Tennessee researchers in an article published online June 27 in JAMA Oncology.

Risk model predicts malignancy of lung nodules on CT
June 28, 2019 -- A new risk-prediction model proved capable of estimating the likelihood that pulmonary nodules detected on CT scans would become malignant in a new study, published online July 27 in Cancer Prevention Research. The model may assist clinicians in managing patients at risk of developing lung cancer. Read More
SIIM: Automated reporting tool optimizes CT lung screening
June 27, 2019 -- DENVER - A computer-assisted reporting tool integrated directly into the radiology workflow bolstered the ability of clinicians to distinguish benign from malignant lung nodules on CT lung screening exams in a new study, presented on Wednesday at the Society for Imaging Informatics in Medicine (SIIM) annual meeting.

VA: Delay in patient diagnosis leads to suicide
June 27, 2019 -- A patient seen at a U.S. Department of Veterans Affairs (VA) hospital committed suicide after a delayed cancer diagnosis, according to an investigation conducted by the VA Office of Inspector General. The report comes a day after a hearing in the U.S. Congress on delays in patient care in the VA system. Read More
