3 ways to lower CT radiation dose across the hospital
May 24, 2019 -- A hospital-wide quality improvement project effectively lowered CT radiation dose by nearly 20%, report researchers from Seattle. They detailed how three initiatives enabled them to achieve this dose reduction in an article published online May 21 in the Journal of the American College of Radiology.  Discuss
CT lung screening risk model cuts false-positive rate
May 23, 2019 -- Using a risk prediction model to figure out which nodules to work up helped reduce the false-positive rate in a CT lung cancer screening trial by more than threefold, compared with rates using previous criteria, according to an article published online May 15 in the Journal of the American College of Radiology.  Discuss
Medicaid expansion boosted cancer screening rates
May 22, 2019 -- The five states and the District of Columbia that expanded their Medicaid coverage after the Patient Protection and Affordable Care Act of 2010 first went into effect showed larger increases in cancer screening rates than states that did not, according to a study published online May 22 in the American Journal of Preventive Medicine.  Discuss
Google AI accurately assesses CT lung screening scans
May 22, 2019 -- An artificial intelligence (AI) model developed by Google can assess cancer risk on CT lung cancer screening studies as well as, or even better than, experienced radiologists -- potentially enabling automated evaluation of these exams, according to research published online March 20 in Nature Medicine.  Discuss
Head CT offers low diagnostic yield for fainting
May 21, 2019 -- More than half of all patients who faint still undergo head CT despite a diagnostic yield of less than 3% for the exam, according to an article published in the May issue of Academic Emergency Medicine. Researchers from Canada say it's high time to cut back on using the test for most patients.  Discuss
Smokers shy away from cancer screening exams
May 17, 2019 -- Individuals who smoke are much less likely than nonsmokers to participate in basic screening exams for breast, prostate, and colorectal cancer, despite clear recommendations from existing guidelines, according to a new study published online May 17 in JAMA Network Open.  Discuss
CT predicts cardiac events in colon cancer patients
May 16, 2019 -- Body composition measurements -- specifically visceral adipose tissue and muscle radiodensity -- obtained from the routine CT scans of patients with colorectal cancer could help identify those at the greatest risk of major adverse cardiac events, according to an article published online May 16 in JAMA Oncology.  Discuss
Is shared decision-making CT lung screening's Trojan horse?
May 9, 2019 -- Has the requirement that high-risk individuals complete a shared decision-making session with their doctors led to disappointing uptake of CT lung cancer screening? Dr. Frederic W. Grannis Jr. believes so, and, in fact, he sees shared decision-making as a deliberate attempt by opponents of screening to sabotage the exam -- much as the Trojan horse led to the downfall of Troy.  Discuss
ARRS: Should CT lung screening programs fear flu season?
May 8, 2019 -- HONOLULU - Is CT lung cancer screening less effective during flu season? Probably not, but screening eligible smokers for respiratory illnesses such as the flu before ordering the exam sharply reduced the need for downstream testing, according to a presentation at the American Roentgen Ray Society (ARRS) annual meeting.  Discuss
CT tube voltage doesn't affect AI FFR-CT analysis
May 8, 2019 -- An artificial intelligence (AI) algorithm for estimating fractional flow reserve on coronary CT angiography (FFR-CT) had the same level of performance when used with CT tube voltages of either 100 or 120 kVp, according to research posted online April 30 in the American Journal of Roentgenology.  Discuss
