AI helps characterize breast masses on ultrasound
February 4, 2020 -- A breast ultrasound artificial intelligence (AI) algorithm was able to differentiate breast masses at a high level of accuracy by combining analysis of B-mode and color Doppler images, according to research published online January 31 in European Radiology. It even yielded comparable performance to experienced radiologists.  Discuss
Ultrasound followed by CT effective for appendicitis
January 30, 2020 -- Ultrasound scans followed by CT if necessary may be the most cost-effective imaging option for patients with suspected appendicitis, according to research published online on January 21 in Pediatrics. The staged intervention approach also resulted in some of the best quality-of-life outcomes for patients.  Discuss
Elastography shows high reproducibility in breast lesions
January 24, 2020 -- Two different ultrasound elastography techniques -- strain elastography and shear-wave elastography -- showed high interoperator reproducibility when scanning breast lesions in a new study, published on January 21 in Ultrasound in Medicine and Biology.  Discuss
2 ultrasound features predict cancer recurrence risk
January 23, 2020 -- Machine learning might one day be able to tell which breast cancer patients will benefit from additional genetic testing. In a recent study, researchers used natural language processing to identify key features from ultrasound reports associated with cancer recurrence risk.  Discuss
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
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
Model predicts metastases in endometrial cancer patients
December 24, 2019 -- Using ultrasound in combination with endometrial biopsy results and clinical characteristics allows clinicians to reliably predict the risk of lymph node metastases in endometrial cancer patients before surgery. Researchers found the model to be superior to risk stratification alone in a study published online December 16 in Ultrasound in Obstetrics and Gynecology.  Discuss
Does thyroid cancer screening lead to overdiagnosis?
December 23, 2019 -- Two studies from the U.S. and South Korea are raising questions about the role of ultrasound screening and thyroid cancer incidence. Researchers specifically address the issue of overdiagnosis in studies published in the December 24/31 issue of the Journal of the American Medical Association.  Discuss
USPSTF reaffirms take on ultrasound AAA screening
December 10, 2019 -- The U.S. Preventive Services Task Force (USPSTF) has reaffirmed with no major changes its 2014 recommendations on using ultrasound to screen for asymptomatic abdominal aortic aneurysm (AAA), in a new statement published online December 10 in the Journal of the American Medical Association.  Discuss
