AI may help cut back on overutilization of CT for PE
August 8, 2019 -- An artificial intelligence (AI) algorithm can predict -- from electronic medical record data -- if a patient is likely to have a pulmonary embolism (PE) prior to receiving CT pulmonary angiography, potentially avoiding unnecessary scans, according to research published online August 7 in JAMA Network Open.  Discuss
Biennial follow-up exams prove safe for CT lung screening
August 8, 2019 -- Biennial CT lung cancer screening is a safe alternative to annual screening, say researchers from Italy. They found that both approaches led to similar reductions in cancer and all-cause mortality in a new analysis of the Multicentric Italian Lung Detection trial published in the September issue of the European Journal of Cancer.  Discuss
USPSTF again dismisses pancreatic cancer screening
August 6, 2019 -- The U.S. Preventive Services Task Force (USPSTF) has reaffirmed its prior decision to recommend against imaging-based screening for pancreatic cancer in asymptomatic individuals, in a recommendation statement published online August 6 in the Journal of the American Medical Association.  Discuss
Brain abnormalities on CT, MRI indicate severe Zika
August 1, 2019 -- Structural abnormalities visible on the brain MRI and CT scans of infants with the Zika virus had a significant association with severe clinical outcomes, especially in those initially affected by the virus during the first trimester of pregnancy, according to a study published online July 31 in JAMA Network Open.  Discuss
CT for hematuria may increase cancer risk, costs
July 30, 2019 -- The diagnostic advantages of using CT to evaluate patients with blood in the urine, or hematuria, may be offset by a bevy of downsides, including increases in patient costs and risk of cancer from radiation exposure, according to a study published July 29 in JAMA Internal Medicine.  Discuss
Why are some CCTA scans ineligible for FFR-CT analysis?
July 29, 2019 -- A significant proportion of coronary CT angiography (CCTA) scans has been deemed ineligible for analysis with fractional flow reserve CT (FFR-CT) in recent studies. An international team of researchers investigated the underlying causes behind this issue in an article published online July 23 in Radiology.  Discuss
AI algorithm helps prioritize urinary stones on CT
July 26, 2019 -- An artificial intelligence (AI) model was highly accurate for detecting urinary tract stones on unenhanced CT studies, enabling priority review of these cases by radiologists and referring physicians in a new study, published online July 24 in Radiology: Artificial Intelligence.  Discuss
More pregnant women are undergoing imaging
July 24, 2019 -- The use of medical imaging during pregnancy has grown in the U.S. and Canada over the past 20 years, with CT and MRI seeing the greatest increases, according to a study published online July 24 in JAMA Network Open.  Discuss
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.  Discuss
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.  Discuss
