Ultrasound detects astronaut's blood clot in space

January 7, 2020 -- An astronaut on the International Space Station using an onboard ultrasound scanner to research the effects of space flight instead detected their own venous thrombosis, according to an article published in the January 2 issue of the New England Journal of Medicine. Discuss

Breast density laws don't boost ultrasound rates

January 7, 2020 -- State laws designed to notify women with dense breast tissue about their options for supplemental imaging may not actually boost the use of ultrasound. A study in the January edition of the Journal of the American College of Radiology found density notification laws did not increase ultrasound rates. Discuss

Flortaucipir-PET shows moderate promise for CTE

January 7, 2020 -- PET imaging with flortaucipir revealed uptake patterns indicative of chronic traumatic encephalopathy (CTE) in a new study published online January 6 in JAMA Neurology, but the tau-binding radiotracer is not quite ready to be declared a reliable biomarker for the condition, the authors noted. Discuss

Ultrasound of infants exposed to Zika predicts long-term risk

January 6, 2020 -- Some infants who were exposed to the Zika virus in utero but who appeared normal at birth later demonstrated delays in development as toddlers, according to a study published online January 6 in JAMA Pediatrics. But imaging tools such as ultrasound and MRI can help indicate which children might be at increased risk. Discuss

Imaging criteria for congenital heart disease released

January 6, 2020 -- A coalition of academic organizations has released a set of appropriate use criteria covering when multimodality imaging should be used to follow up patients with congenital heart disease. The guidelines were published online January 6 in the Journal of the American College of Cardiology. Discuss

MRI sheds light on adolescent brain pathways

January 6, 2020 -- Why does your teenager drive you crazy? A new study used MRI tools such as functional MRI and diffusion-weighted imaging to shed light on structural pathways in the brain during adolescence -- a time of rapid brain development in humans. Discuss

CT bucks trend of flat imaging use rates

January 3, 2020 -- Diagnostic imaging usage rates in the U.S. have begun to decrease or stabilize in recent years for all imaging modalities with the exception of CT, for which the rate has increased in the last few years, according to an article published online December 31 in Radiology. Discuss

PET shows tau better predicts brain atrophy than amyloid

January 3, 2020 -- PET scans comparing the location and magnitude of tau protein accumulation have shown that tau better predicts future brain atrophy in patients with Alzheimer's disease compared with amyloid deposition -- and a year or more in advance, according to a study published online January 1 in Science Translational Medicine. Discuss

AI performs well in large-scale breast screening study

January 2, 2020 -- In a large-scale study that replicated real-world breast screening conditions, an artificial intelligence (AI) algorithm performed well in interpreting mammograms, reducing both false positives and false negatives. The findings were published January 1 in Nature. Discuss

Cinematic rendering enhances view of vascular anomalies

January 2, 2020 -- Radiologists from Johns Hopkins University applied cinematic rendering to the clinical management of congenital vascular anomalies and uncovered critical features of patient anatomy and pathology that were not evident using traditional volume rendering techniques or conventional CT.
