Providing Ultrasound Information to Enhance Patient Care and Safety
Contrast-enhanced subharmonic imaging revealed prostate cancers not detected by MRI, according to researchers at Thomas Jefferson University. The technique involves imaging of microbubble ultrasound contrast agents and reportedly helps suppress background tissues in images.
Mean interpretation time of automated breast ultrasound images by novice radiologists decreased by 3.1 seconds for every 10 ABUS examinations interpreted, suggesting that the ABUS learning curve is similar to that of other breast imaging technologies, researchers reported in Academic Radiology. Overall, novice radiologists' average interpretation time was 2 minutes, intermediate radiologists had a mean time of 2.6 minutes and advanced radiologists took an average of 2.1 minutes to interpret ABUS images.

A portable, smartphone-connected ultrasound device expanded access to diagnostic imaging in a pilot program at hospitals in rural Kenya. The device is based on a microchip containing 9,000 tiny metal transducers and has an artificial intelligence component that might eventually allow self-exams in areas with minimal access to health care professionals.
A study in a radiology journal found that 55.3% of US radiologists are generalists, meaning they allotted less than 36% of their work to a specific subspecialty. The findings, based on an analysis of 2012-2014 insurance claims data involving 33,090 radiologists, also showed that neuroradiology, nuclear medicine, interventional radiology and abdominal, breast, musculoskeletal and vascular imaging were the top radiology subspecialties.

Patients with triglyceride levels higher than 2,000 mg/dL were more than four times as likely to have pancreatitis as patients whose triglyceride levels were between 1,000 mg/dL and 1,999 mg/dL, according to a study published in Endocrine Practice. Younger age and the presence of gallstone disease were also found to be risk factors.
A study presented at the European Association for the Study of the Liver's annual meeting found autoimmune hepatitis during pregnancy was associated with higher risks of adverse birth outcomes, including preterm birth and having an infant who was small for gestational age. The findings, based on data for 1,947 Danish women with autoimmune hepatitis and 19,470 matched controls, did not show any clear association between adverse birth outcomes and immunosuppression.
A high-power longitudinal kidney study involving 3,205 participants, led by researchers at Oxford University, is planned to launch in UK general practices this month. Researchers will be observing the progression of chronic kidney disease in people aged 60 or older.
A study presented at the International Liver Congress 2018 revealed that 14% of patients with nonalcoholic fatty liver disease who participated in a web-based lifestyle counseling program achieved the weight loss target of 10%, and were more likely to achieve normal alanine aminotransferase levels than those in the group-based program. Italian researchers said the web-based program was not less effective and not inferior to the group-based program and showed long-term efficacy.
PwC's Health Research Institute estimates that about 1.7 million people in 10 states could be affected by waiver requests to impose work requirements on Medicaid beneficiaries. Almost $8 billion in annual medical expenditures would be affected by the requirements, according to the report.
