CT CAC predicts risk of death in smokers
February 28, 2020 -- The presence of coronary artery calcium (CAC) on CT scans was associated with an increased risk of death from cardiovascular diseases, cancer, and all causes combined -- including for a subset of smokers eligible for CT lung cancer screening -- in a study published in the February issue of Atherosclerosis.  Discuss
Older endurance athletes have risk of enlarged aorta
February 28, 2020 -- Older endurance athletes may be prone to heart conditions with a relatively high risk of death. Echocardiographic imaging helped identify an enlarged aorta in 25% of older athletes in a new study, published on February 26 in JAMA Cardiology.  Discuss
MRI finds gender differences even in healthy hearts
February 27, 2020 -- An investigational 4D flow MRI sequence has helped researchers confirm different blood flow characteristics in the hearts of young, healthy men and women. The findings could help clinicians set benchmarks for comparisons with unhealthy patients, according to a study published February 27 in Radiology: Cardiothoracic Imaging.  Discuss
Ultrasound performance mixed in breast cancer survivors
February 27, 2020 -- Supplemental screening ultrasound shows a mixed performance in women with a personal history of breast cancer, with lower sensitivity and a higher interval cancer rate. But the modality also had higher specificity, according to a study published online February 25 in Radiology.  Discuss
What issues are hindering AI's utility in radiology?
February 26, 2020 -- Artificial intelligence (AI) technology has much potential in radiology, but several key issues are limiting its current clinical utility, according to a presentation on Tuesday at a public workshop held by the U.S. Food and Drug Administration on the evolving role of AI in radiology.  Discuss
CT again tops DNA tests for early coronavirus detection
February 26, 2020 -- In a study covering more than 1,000 confirmed cases of the novel coronavirus disease, chest CT proved to be more accurate than the standard method of DNA testing for early diagnosis of the disease in high-risk individuals.

MRI suggests main reason for psychotic relapses
February 26, 2020 -- MR images have revealed decreased cortical thickness in people on antipsychotic drugs compared with those on placebo. But in both cases, their relapse back into psychosis may be due more to structural brain change than a lack of medication, according to a study published February 26 in JAMA Psychiatry.  Discuss
